Benefits of Auto-Calibration
• Accuracy over Temperature. Meters drift over temperature.
Moreover, hysteresis in drift may compromise accuracy permanently
and require the meter to be returned for re-calibration. GE’s autocalibration insures that normal drift caused by ambient temperature
movement does not affect accuracy.
• Accuracy over Time. Since the majority of components within the
meter are being re-calibrated on a regular interval, the meter will hold
accuracy longer than non-calibrating meters.
• Better Out of Box Test Results. Components from new meters
sometimes need up to 1000 hours to stabilize. Using auto-calibration,
the components will be recalibrated over the life of the meter.
• Less Maintenance / Lower Ownership Cost. Since the meter autocalibrates, less meters will be removed from the field for calibration.

EPM 9900 – Precise Time Synchronization
•
IRIG-B: The EPM 9900 meter’s time can be synchronized to the signal from a GPS IRIG-B satellite. IRIG-B has a
pulse rate of 100 pulses-per-second with an index count of 10 msecs over its one second time frame. IRIG-B
sync has a time accuracy of better than 100 microseconds.
• Network Time Protocol server: You can set up the meter’s Ethernet port to synchronize time using a
Network Time Protocol (NTP) server. Typical accuracy is achieved to at least 1 msec, depending on network
configuration.
• Line Frequency clock synchronization: The EPM 9900 meter’s time can be synchronized to the AC
frequency.
• Internal clock crystal: The EPM 9900 meter’s internal clock crystal is accurate to 20ppm. It can be used if
IRIG-B is not connected and/or other synchronization methods are not being used.
• DNP time synchronization: Using Communicator EXTTM software, you can set the meter to request time
synchronization from the DNP Master. Requests can be made from once per minute to once per day.
65
EPM 9900 - Power Quality and System
Reliability Recording
• Measure power quality indices such as voltage
anomalies, harmonics, flicker, imbalances and
many other conditions
• Record waveform event on sags and swells,
including peak and duration of the event, with
microsecond resolution
• Analyze damaging high speed positive and
negative transients in the MHz range,
which can damage equipment
• Report on events using industry certified IEC
61000-4-30 Class A standards and EN50160
reports
66
EPM 9900 - System Reliability
Improvements
•
Monitor voltage reliability system wide to insure
proper voltage distribution
•
Analyze critical feeds to determine if power
distribution is optimized, i.e.; Is PF too high? Is
voltage reliable? Are there too many drops on
the line?
•
Conduct forensic analysis on feeds and
equipment to provide proactive awareness of
problems before they occur
•
Audit power system for weakness or
troubleshoot within the power system
•
Alert engineers by email or on a display when a
critical alarm occurs!

IEC 61000-4-30 Class A
Certified Compliance Reporting
What Is IEC 61000-4-30 Class A?
•
It is the definitive Industry Standard on Voltage Reliability Monitoring
•
It provides a comprehensive measurement of power quality including:
1.
Voltage Interruptions
2.
Harmonics (As per EN61000-4-7)
3.
Inter-harmonics
4.
Frequency
5.
Flicker (As per EN61000-4-15)
6.
Imbalances (Unbalances)
72
IEC 61000-4-30 Class A
Certified Compliance Reporting
Why is IEC 61000-4-30 Class A so Important?
•
It is designed to address the issue of multiple recorders using
differing DSP techniques producing differing results.
•
This Standard normalizes the digital signal processing so that all
monitors report the same results for the same occurrence
•
This eliminates confusion in the industry
•
False Claims -- There are multitudes of instruments making
false claims to be compliant with the class A standard. There is
only one Lab known to GE that can certify a monitor, Power
Standard Labs in Northern California
•
It is imperative to ask the monitoring company to providing it
certification documents.

EPM 9900 - RTU Master Capability
RTU Master Makes EPM 9900
into an RTU
Mastering - Set Up Modbus registers to allow the Nexus
meters to poll registers from slave devices
Logging - Once the profile is set up and the meter is
polling data from the slave devices, then the data can be
logged in the historical log profiles for later retrieval
Modbus RTU Serial
 Alarming – The modus registers can also have limits
set points that could be used trigger alarms set-points,
send emails or log events in internal memory
Communication – All Data is available via multiple
communication paths including RS485 and Ethernet
 Perfect for Distribution Automation – Utilizing EPM
meters, distribution feeders can be automated WITHOUT
changing protective equipment.
