1.0 Product Introduction
The RD-30 Portable Three-phase Electricity Standard utilizes a lightweight, compact package
while providing a high level of accuracy through design innovations. The RD-30 has a typical
accuracy of 0.01% and a maximum worst case accuracy specification of 0.04%. This specification
includes variables of stability, temperature, power factor, traceability uncertainty, and test system
errors. In addition, this accuracy applies across the entire voltage and current operating range of
the product for an entire year.
The RD-30 utilizes Radian’s new Dytronic measurement technology consisting of a Radian
designed Integrating Analog to Digital Signal Converter. The RD-30’s Dytronic A/D Converter
is combined with Radian’s renowned electronically compensated voltage and current input
transformers and a hermetically sealed reference set to provide the highest degree of accuracy,
stability and versatility offered in a portable three-phase electricity standard.
The RD-30 provides four quadrant three-phase simultaneous measurements for active, reactive,
and apparent energy and power with forward and reverse energy flow also measured. The
potential input, current input and auxiliary power input are totally autoranging. This autoranging
feature was pioneered by Radian Research and makes it impossible to damage the unit by applying
a signal to the wrong tap. The potential input range is 30 to 630 volts, the current input range is
available as either 120 amps or 200 amps per phase. The auxiliary power ranges from 60 to 630
volts.
In the field, the RD-30 can be used with a controlled current load, or it can be used with clamp-on
current transformers available from Radian Research to perform customer load tests. In this field
application, the optional power analysis capability can analyze customer load through the 204th
harmonic order. In addition, for improved efficiency, the RD-30 optionally can automatically
calculate and display the error of the meter under test.

The RD-30 also provides a serial communications port which allows direct connection to the RS232 serial port of a personal computer. RD-30s with the Built-in Computer option come with RRMobileSuite software.
The RD-30 is available in a variety of models offering measurement functions and options to suit
specific needs.
1.1 Enhanced Design Features
Many design features have been added or improved through the engineering process of designing
the RD-30 Dytronic. The addition of A/D and DSP technology, increased PC support and an
enhanced version of Radian’s revolutionary voltage and current transformer input design make
the RD-30 the benchmark of portable standards, second only to the RD-31 portable threephase
reference standard. The RD-30 utilizes Radian Research designed Analog/Digital circuitry
coupled with Digital Signal Processing techniques. These advancements provide a high degree
of flexibility including simultaneous multifunction measurements and harmonics analysis
capabilities.
A/D and DSP Technology
In order to accelerate the testing process, Radian Research has designed and incorporated a
custom integrating Analog to Digital Converter into the RD-30. There are separate A/D circuits
for both the voltage and current axes. Couple this enhancement with the utilization of DSP
technology and the RD-30’s abilities are greatly enhanced. The RD-30 can effortlessly collect
the converted digital signals from the A/D converters and process the data to display every
measurement function supported during a single collection of voltage and current data.

where a high level of accuracy is desired. The optional built-in comparator allows for automatic
test result calculations of the meter being tested. 1.5 Power Analysis
Unlike off-the-shelf A/D Converters used in other instruments, Radian’s Dytronic
A/D Converter is specifically designed and optimized for power and energy measurement. This
unique design allows the RD-30 to accurately measure non- sinusoidal waveforms up to and
including the 204th harmonic order. Measurement parameters include the phase and amplitude of
each harmonic as well as the total harmonic distortion. The unprecedented accuracy of measuring
distorted waveforms combines with this optional powerc analysis capability to clearly distinguish
the RD-30 as the definitive portable three-phase electricity standard for both meter testing and
power quality applications. This power analysis option is also useful when testing meters using
customer load.
1.6 Customer Load Testing
For those applications where meter testing with customer load is desired, the RD-30 is an
obvious choice because of its ability to accurately measure energy and power even with distorted
waveforms. The optional clamp-on current transformer inputs on each phase allows for testing
the meter using customer load without the need of interrupting service.

RD-30 Operations Manual
Operations Overview
4.0 Operations Overview
4.1 Measurement Principle
The measurement principle is based upon the fundamentals of a high-speed charge-balance
integrating analog to digital signal converter. This is a Radian innovation, but it is based upon
accepted metrology parameters. Radian Research implemented its own analog to digital converter
in the Dytronic family of standards which are specifically designed for power measurement. In order
to measure power and energy with extreme accuracy and wide bandwidth, extensive requirements
must be imposed on the converter.
The RD-30 Dytronic utilizes two separate A/D converters. One accepts a current signal and is
linked with two current references. The other accepts a voltage signal and is linked with two voltage
references. These of course are for the analog voltage and current inputs of the RD-30. Both
operate independently to provide the digital signal processor with signals accurate enough to meet
the requirements of a true portable electricity standard.
By designing an analog to digital converter specifically for power and energy measurements,
Radian is able to reduce many errors associated with commercial A/D circuits. Gain error,
charge timer resolution, signal to noise ratio and signal distortion were major areas dealt with and
improved in development.
4.2 Internal Reference Set
The RD-30’s internal reference set is hermetically sealed in order to protect it from environmental
variables. The internal reference set consists of a voltage reference, a resistive reference and a crystal
time reference.
4.3 Output Stage
The RD-30’s output stage displays the measurements and provides pulse outputs for the selected
measurements. Computer control, with Radian software, allows for customization of output
information, such as programmable pulse output constants.
17
RD-30 Operations Manual
Operations Overview
4.4 Voltage and Current Inputs*
The voltage and current inputs are completely autoranging – a design feature that was pioneered
by Radian Research with the RM-10 in 1985. The voltage and current inputs consist of a toroidal
autoranging electronically compensated transformer. The Radian toroid transformer provides
superior immunity to stray fields and the electronic compensation eliminates practically all of the
transformer error.
4.5 Auxiliary Power Inputs
Auxiliary power is required to power the internal workings of the RD-30. It may be derived from
the same signal as the potential input providing that there are sufficient volt-amperes available.
Auxiliary power may also be supplied independent from the potential input source. The power
supply for the RD-30 is a very advanced switching power supply which is inherently capable of
converting the available input power to regulated power over the entire operating range. The converter is so effective at this that the input may be changed freely between the ranges of 60 and 630
VAC during operation without a measurable effect upon operation.
The connections have been updated to an insulated socket design. The Potential Input and Auxiliary Power Input are 4mm connections and the Current Inputs are 6mm connections (bolt-on
design for 200 amp models). It is now virtually impossible to touch any live connection while the
unit is in operation.

RD-30 Operations Manual
Operations Overview
4.6 Clamp-On CT Input
The RD-30 features a clamp-on current transformer input. This input can only be utilized with
Radian approved current transformers, as others do not have the inherent accuracy needed to
optimize the RD-30’s accuracy and stability. The input is a seven-pin connector that provides
power, serial communications, and an input for specific clamp-on current transformers.
4.7 Pulse Inputs
The RD-30 Pulse Inputs consist of BNC connectors labeled 1, 2, 3. These inputs are open collector. Phase A input is labeled as 1, Phase B input is labeled as 2 and Phase C input is labeled as
3. While doing a meter test a RM-1S Remote Reset Switch may be connected to input 3 (Phase C
input) and can be used to gate (start/stop/reset) all three inputs simultaneously. Or, instead of the
RM-1S, any of the Radian pickups may be connected to input 3 (Phase C input). The pickups consist of the RM-1H, RM-DS, and RM-KYZ, all which can be used to test various electricity meters.
While doing a standards test all three inputs can be used individually or simultaneously.

RD-30 Operations Manual
Operations Overview
4.8 Pulse Outputs
The RD-30 Pulse Outputs consist of BNC connectors labeled 1, 2, 3. These outputs are open
collector. The factory default setting is Output 1 = Total Watthours, Output 2 = Total VARhours,
Output 3 = Total VAhours. However all three outputs are programmable by the customer for per
phase energy or total energy.
4.9 Analog Sense Input
The optional Analog Sense functionality allows the RD-30 to effectively test transducers as well
as first generation electronic meters that have an analog output for calibration. The RD-30 will not
only test these instruments, but it will also automatically calculate and display the error.

RD-30 Operations Manual
Operations Overview
4.10 Serial Port Communications Terminal
The communications terminal is interfaced via a DB-9 connector. Through the use of this
terminal, a myriad of capabilities present themselves. Not only can each RD-30 software package
be utilized, the RD-30 can actually be re-calibrated through this terminal. Additionally, the flash
memory storage for both the DSP and Xilinx programs is accessible through this terminal making
the RD-30 field upgradable.
4.11 Pickup Terminal
The sensor input terminal on the RD-30 comes in the form of a 4 Pin Lemo connector. Radian
Disk sensors, infrared and visible LED optical pickups can be utilized to sense disk rotation
or equivalent revolutions. See Section 2.1 Generating RD-30 Model Numbers for further
information.
4.12 Chasis Ground, Guard, Neutral
Chassis Ground – ideally tied to the best available earth ground. If the RD-30 is mounted in a
rack, no connection is required. The Chassis grounds main purpose is for safety.
21
RD-30 Operations Manual
Operations Overview
Guard – should be tied to the common of the Wye source for Wye usage and left to float in Delta
use applications. Because the Analog Sense is common with the Guard ground, care must be
taken to avoid ground loop problems.
V1, 2, 3 / VN – the three VN connections should be tied together, via twisted wire pair, with their associated Potential Inputs (V1, V2, V3). At the Device Under Test (DUT), each VN should be broken
out from its associated twisted wire pair and each tied to the DUT Neutral with the three Potentials
(V1, V2, V3) tied to the three Potential connections of the DUT. The three Potentials (V1, V2, V3) of
the DUT should be tied to the associated three Potentials of the source. If using a Wye source, the
Neutral from the DUT, containing the three VNs, should be tied to the Wye source neutral. If using
a Delta source, the DUT Neutral, containing the three VNs, should be allowed to float.

RD-30 Operations Manual
Service & Routine Maintenance
5.0 Service & Routine Maintenance
The RD-30 Dytronic portable electricity Standard is virtually maintenance free. The elimination
of all contacts, switches and tap selections on the primary side of the input transformers
significantly improves reliability by eliminating both service components and the opportunity for
operator error. Other than cleaning of the outside surface and the yearly recalibration, no routine
maintenance is required.
5.1 Cleaning
Cleaning of the RD-30 may be performed with a clean, dry lint-free cloth dampened slightly with
a mild window cleaner. The areas around the top terminals should be buffed dry with another
cloth, which is completely clean and totally dry.
5.2 Repair
It is recommended that Radian Research perform all repairs. We have excellent automated testers
with which every internal module can be tested quickly to original factory specifications. A final
calibration and quality control inspection to original factory specifications is performed quickly
and thoroughly. If the RD-30 is in need of repair then contact Radian Research or your local
Radian Research Representative and request a Return Material Authorization (RMA) number.
You will need to provide the model number and serial number as well as a detailed description of
the problem.
5.3 Recalibration
Recalibration is recommended yearly. A periodic cross check against a Radian RD-21 or RD22 or RD-31 is recommended to preclude the possibility of a failure in either. Prudence would
dictate having a dedicated RD-21 or RD-22 or RD-31 for cross check purposes. With the RD21 or RD-22 or RD-31 it is feasible to sample test units at various points as a “backup” test.
In addition, it is recommended that one take advantage of Radian’s recalibration service as a
very cost effective method to maintain traceability Radian Research’s Calibration Laboratory
maintains primary transfer standards that are directly traceable to NIST. Radian Research’s
Calibration Laboratory also maintains several RS-703A Automated Calibration Systems as
working secondary standards.
25
RD-30 Operations Manual
Service & Routine Maintenance
The RS-703A Automated Calibration System collects a data point on a RD Radian standard
every 5 (five) seconds on up to sixteen standards simultaneously, collecting literally thousands
of data points on an overnight run. In addition each RS-703A provides computer control over
an environmental chamber to ensure proper temperature range operation of the standard being
tested. Please contact Radian Research for further information on recalibration and recertification
services.
5.4 Fuse Replacement
Fuse replacement is not very likely because of the elimination of the primary side switching.
However, fuses are included and are accessible without disassembly. There are four fuses: three
potential input and one auxiliary power. All fuses are located under the red potential and auxiliary
power inputs. Fuse replacement is performed as follows:
o
1. Remove the red terminal of the circuit with bad fuse by rotating 90
counter-clockwise and then lift out the unit.
2. Remove the fuse by rotating it clockwise in the retaining screw.
3. Replace the fuse by rotating it clockwise in the retaining fuse.
o
4. Replace the terminal in the same orientation it was removed and rotate it 90
clockwise to lock in place.

Warranty
6.0 Warranty
Radian Research warrants each of our products to be free from defects in material and
workmanship. Our obligation under this warranty is to repair or replace any instrument
or component therein which, within two years after shipment, proved to be defective upon
examination. Radian will pay local domestic surface freight costs for return shipment of the
product back to the customer.
In addition, all Radian Dytronic Multi-measurement Standards are warranted to be substantially
stable in calibration over time. If within one year after factory calibration the standard does not
meet its specifications, we will repair and recalibrate the unit at our cost. Our calibration records
retain the value of each of the three reference elements to six decimal positions.
For a period of ten years, we warranty any fully autoranging reference standard from catastrophic
failure caused by failure to range properly. This warranty is voided by disassembly of the units
beyond removal of the case for recalibration.
If warranty service is required then contact Radian Research or your local Radian Research
Representative and request a Return Material Authorization (RMA) number. You will need to
provide the model number and serial number as well as a detailed description of the problem.

8.1).
Step 3
Using the stylus, single tap on the Run Meter Test icon. The meter test screen will now appear
(see Section 8.8)
Step 4
Use the onscreen keyboard (see Section 8.10) to enter the DUT serial number.
Step 5
Use the onscreen keyboard to enter DUT Kh value.
Note: If performing KYZ testing, the meter’s Ke factor should be entered in place of a
Kh value. Ke is the watthour pulse constant of each pulse from the pulse initiator (KYZ).
The value of the Ke is dependent upon the meter Kh and the type of test conducted. The
Ke factor of any meter may be calculated by using the following constants.
Kh = Watthour constant. The number of watthours represented by one revolution
of the disk. Also called the disk constant.
Mp = Number of revolutions per pulse
Example Calculation:
Ke = (Kh) x (Mp); if Kh = 1.8 watthours per revolution and Mp = 1 revolution per
12 pulses, then,
Ke = (1.8 Wh/1 rev) x (1 rev/12 pulses) = (1.8 Wh/12 pulses) = 0.15 Wh/pulse
Step 6
Use the stylus and the arrow keys on the Meter Test screen to enter/select the Pulses per Kh, #
Seconds or Pulses, DUT Elements, Test Type, Standard Elements, Phase and State. Repeat Step 6
for all applicable DUT(s).
Note: If performing KYZ testing, enter one pulse per Ke value.

RR-DS Meter Disk Sensor
The RR-DS is a reflective pickup assembly used to sense the disk rotation of an induction type meter. The pulses generated by the RM-DS are fed into the PICKUP port of the RD-30. Evaluation of
different types of meter designs is fully automated when the Built-in Computer option is utilized.
The RR-DS is available in two (2) different mounting options. The RR-DS/f Disk Sensor with Field
Mount features a Velcro strap that attaches around the meter cover. This allows the sensor to sense
disk rotation from the side of the meter. The RR-DS/sm Disk Sensor with Suction Mount features
an L-bracket with three (3) suction cups that attach to the front of the meter cover. This allows the
sensor to sense disk rotation from the front of the meter.
RR-1H Optical Pickup for Infrared LED
The RR-1H is used to sense the infrared pulses from the calibration LED of solid-state meters. The
pulses from the RR-1H are fed into the PICKUP port of the RD-30. Evaluation of different types of
meter designs is fully automated when the Built-in Computer option is utilized. The wide angular
displacement of this sensor allows for fast, non-critical alignment. Also, automatic gain control circuitry of the RR-1H assures operation in all ambient sunlight conditions. The RR-1H/v is available
for those solid-state meters with a visible calibration LED, and terminates in a BNC Connector instead
of a lemo connector. Therefore, the RR-1H/v attaches to port 1 instead of the pickup terminal.

RM-OA Optical Adapter
The RM-OA Optical Adapter is used with solid-state meters whose infrared calibration pulse is emitted from the optical communications port. The RM-OA magnetically couples to the communication
port of solid-state meters. The suction cup of the RD-1H is attached to the clear polycarbonate cover
of the RM-OA. The RM-OA incorporates a rare earth permanent magnet for exceptional holding
power over the life of the product.
RR-KYZ Pulse Input Adapter
The RR-KYZ Pulse Input Adapter is used to sense the KYZ output pulses of induction or solid-state
meters. The Pulses received from the meter’s KYZ output are conditioned and fed into the PICKUP
port on the RD-30. The testing of KYZ equipped meters is done automatically with the Built-in
Computer option of the RD-30.

RD Current Connector Locking Mechanisim
Appendix: RD Current Connector Locking Mechanism
The Radian RD-2X and RD-3X (120A) Dytronic Standards utilize 6mm locking style connectors
for the current inputs.
Note: These connectors are very specialized and feature beveled edges and a locking ring. Do
NOT use straight ¼” current connector studs. Radian offers various jumpers and adaptors to fit
most applications.
When connecting to the current inputs, insert the 6mm current plugs slowly into the current input
receptacles on the RD standard. Do not use excessive pressure when inserting. Only a minimal
amount of force is required to engage the locking mechanism.
RD-3x Shown
RD-2x Shown
NOTE: Pushing the current plug too hard may engage and then disengage the locking mechanism
in one move. To prevent this, gently push the plug into the receptacle and allow the lock to
engage.
Once the locking mechanism is engaged, pull on the current plug outward. You should NOT be
able to remove the plug.
