1. Product Introduction
1.1. Introduction RTU
RT-200P is embedded in Distribution Automation SF6 gas insulated load break switch
(Pole mount) control box.
It receives measurement information (3 phases current &
voltages) and status information from Switch, and meters current and voltage, detects FI,
Line cut, Live line/Dead line, Unbalance, Sectionalizer optimized for remote control and
automation systems.
RT-200P monitors not only electric quality of distribution line but also, provides Section
operation in case of fault occurring and minimize its fault area.
All events occurring in the distribution line, are saved and provides fault analysis. With
using DNP3.0 Protocol, provides monitored status to SCADA for switch operation. Not
only DNP3.0 Protocol, other communication protocols can be provided by user’s request.
As well as, controlling a switch by receiving Control Signal from SCADA, provides
Distribution Automation and minimize a fault area.

IEC 60870-5-104 (also known as IEC 870-5-104) is an international standard,
released in 2000 by the IEC (International Electro technical Commission). As can
be seen from the standard's full designation 'Network access for IEC 60870-5-101
using standard transport profiles', its application layer is based on IEC 60870-5101. IEC 60870-5-104 enables communication between control station and
substation via a standard TCP/IP network. The TCP protocol is used for
connection-oriented secure data transmission.

Event Record
The event recorder feature allows the time tagging of any change of state (Event) in the relay. As an event
occurs, the actual event condition is logged as a record along with a time and date stamp to a resolution
of 1 millisecond. There is capacity for a maximum of
1500 event records that can be stored in the relay
and when the event buffer is full any new record will over-write the oldest.
All events can be uploaded over the data communications channel(s) and can be displayed in the ‘RManager’ SW package in chronological order, allowing the sequence of events to be viewed.
Events are also made available spontaneously to an Modbus RTU or DPN 3.0 compliant control system.

6. Fault Indication
The controller has many different detection features, described in this section. In summary it operates
as follows:
⚫
The fault Detection Elements are Phase, Earth, and Sensitive Earth Fault (SEF). Each individual
element can be programmed to log a fault detection depending on the relevant setting.
⚫
In addition to the Detection Settings there are Operator Settings. This group of settings is
Independent of the Detection Settings and it changes the main functionality of the Load
Break Switch.
The phase, earth and SEF fault detection elements are monitored with independent definite time
and fault current settings.
A pickup event is generated for each element if the current exceeds the fault current setting for that
element.
A pickup normally initiates a timer which runs for the definite time setting for that element.
When
this timer expires a fault is said to have occurred and is reported in the Event Log.
The current level at which the definite time timer starts can be modified by a multiplier in the case
of Cold Load Pickup Condition and definite time timer start is restrained in the case of Inrush
Condition.
When all pickups have reset, a peak current event is generated for each element that have picked
up.
A peak current event is a record of the maximum current measured between fault pickup and fault
reset.
6.1. Fault Indication
Distribution power system is usually Radial Network. Recloser controller or protection relay will
detect the failure of the line, and trip the circuit breaker or Recloser in a main point of power
system. The installation location of the LBS located between the protections switches. LBS is
resolved, the fault section and isolation from the fault section and the remaining sections of the
power system can be restored. Negative Phase Sequence detection is an additional over current
element and allows more reliable detection of certain types of faults.
RT-200P(FRTU) is the LBS controller, and rapid section isolation of fault line and restoration of
normal line by distribution automation system(DAS) which has the function of fault detection and
remote communication.
The following figure shows the fault detection and restoration of sequence. RT-200P(FRTU) is
detected the “failure” when the line voltage is dropped below the voltage Off-Level that the
measured the phase current, N-phase current over than the pickup set and maintains longer than

indication from the LBS controller L1 ~ L5 and Recloser R failure be detected to know through
communication.
Recloser lockout after a fault section, DAS indicates the fault section and isolates it by sending
Open command to the controllers of LBS L3, L4. Wherein L5 is to supply power from the back of
a loop Tie breaker.

At the temporary fault, distribution lines are restored automatically by a reclosing. The fault
indication of RT-200P(FRTU) can be reset by push button on the front panel or by remote reset
command. Also, it can be reset automatically when the line is energized.

using this function, the fault indication can respond only to fault currents from main source, not
from dispersed sources in consumer area of the distribution line. As a result, the faulted section in
45

the line can be discriminated precisely.

6.2. Cold load PickUp
Cold load pickup is the phenomenon that takes place when a distribution circuit is reenergized
following an extended outage of that circuit. This is called Cold Load and Cold Load Pickup function
is to prevent and distinguish Cold Load from the real fault current.
Cold load mode, the fault detection, pickup level is changed by the times of Cold load Multiplier
(1~10) and this is in the instantaneous element. . If the transient current goes down and retains
below the pickup level within Cold Load Duration, then the normal sequence mode is restored. This
setting phase fault and earth fault detection function is applied to. Cold Load Multiplier set to ‘0’,
the function is disable to the Cold Load Pickup.

6.3. Operation of Inrush
When closing onto a typical load there is always a short lived inrush current caused by, for example,
transformer magnetization currents, low resistance lamp filaments and motors starting. Inrush
Restraint inhibits fault detection when inrush current occurs.
Inrush restraint works by raising the phase and earth Threshold Currents for a short period of time
to allow the inrush to flow.
The inrush time and multiplier settings are specified on:

6.4. SEF (Sensitive Earth Fault) Detection
On the non-grounded network, it is hard to detect fault current because ground current of nongrounded network is so small. Therefore, FTU-P200 is designed to measure zero-sequence values
from either external core Balanced Current Transformer (or ZCT) or Residual Connection of 3 Phase
Current Transformers to detect earth fault in the non-grounded network. This function is generally
called SEF detection.
In case of earth fault in the non-grounded network, since very small fault current due to line
capacitance component flows into the fault point from both sides, SEF detection also considers the
fault direction even in the radial network. Maximum Torque Angle is for setting the phase difference
between zero-sequence voltage and zero-sequence current, and the protection zone is between 90° and +90° on the basis of Maximum Torque Angle. And it can be used for alarm.
[Fig. 6-9] Phase diagram of SEF
6.5. Role of the Sectionalizer(Auto Sectionalizing)
The Load Break Switch (LBS) is equipped with automatic sectionalizing logic. The sectionalizing logic
opens the LBS during the dead time of an upstream Recloser after it has tripped and closed a
number of times as configured by the user.
It’s the function to open LBS and disconnect the faulty section from the distribution Feeder
automatically before the Recloser or reclosing relay of CB lockouts. The condition to open
48
Load Break Switch Control
RT-200P
automatically is the fault count. FTU detects and counts the fault and opens LBS if the count reaches
the setting value. The default count setting is two. It means that FTU allows the 1st reclosing success
of the upstream Recloser or reclosing relay of CB without sectionalizing in case of temporary fault.
[Fig. 6-10] Typical time sequence of sectionalizing
Caution: Pay attention to the sectionalizer setting according to the Operation Open Time and Recloser
setting of Mechanism.
Sectionalizer works normally during Recloser Reclosing time
Incorrect example: Recloser Reclosing Time shorter than LBS operation time.
In this case, the LBS cuts off the fault current, which can cause a serious problem.
Note) After Sectionalizer Trip operation, FI Reset must be done for "close" operation.
49

6.6. Phase Loss Detection
It’s the definite time under-voltage function only when at least one phase has normal voltage. It has
hysteresis characteristics. Voltage On level, Off level, and Delay time settings are needed for this
function.
6.7. Phase Sync. Check
RT-200P monitors the phase angle difference between source and load side voltages of LBS. If the
angle difference is larger than the setting and maintains longer than the set time, an alarm is
generated. The alarm is useful to close LBS which is installed at the tie point of two feeders from
the separated substation. FTU doesn’t include the result of sync. Check in the close interlock
conditions. Be cautious of closing tie switch.
6.8. Sectionalizer Inhibit
In the basic FI operation, when no voltage is detected by the Recloser operation of the previous
stage in the current state above the pickup current, a fault indicator occurs.
When Inhibit is activated, the no-voltage condition is excluded and when the current exceeds the
pickup, the fault indicator is activated. At this time, the Fault Indicator condition turns off the
indicator after Auto FI Reset Time.

Power Quality
Menu to set parameters for detecting the short and long term voltage variations.
The alarm level and detection delay time of voltage sag, voltage swell, and outage can be set. The
distribution line’s rated voltage set at system parameter becomes the base of the alarm level for
voltage sag, voltage swell, and outage.
- Sag
A sag (also known as dip) is a reduction to between 30% and 95% in RMS voltage or current at the
power frequency for a short period of time from 0.5 to 10 cycles.
Voltage sags are widely recognized as among the most common and important aspects of power
quality problems affecting industrial and commercial customers. They are particularly troublesome.
Since they occur randomly and are difficult to predict.
Voltage sags are normally associated with system faults on the distribution system, sudden increase
in system loads, lightning strikes or starting of large load like induction motors. It is not possible to
eliminate faults on a system. One of the most common causes of faults occurring on high-voltage
transmission systems is a lightning strike. When there is a fault caused by a lightning strike, the
voltage can sag to 50% of the standard range and can last from four to seven cycles. Most loads will
be tripped off when encounter this type of voltage level.

- Swell
A swell (also known as momentary overvoltage) is an increase in RMS Voltage to between 105% and 150%
for duration from 0.5 to 10 cycles. Swells are commonly caused by system conditions, switching off a large
load or energizing a large capacitor bank. A swell can occur during a single line-to-ground fault (SLGF)
with a temporary voltage rise on the unfaulted phases. They are not as common as voltage sags and are
characterized also by both the magnitude and duration. During a fault condition, the severity of a voltage
swell is very much dependent on the system impedance, location of the fault and grounding. The effect
of the type of disturbance would be hardware failure in the equipment due to overheating.

– Interruption
An interruption occurs when there is a reduction of the supply voltage or load current to between
10% and 49% for duration from 0.5 to 10 cycles. Possible causes would be circuit breakers responding
to over load, lightning and faults. Interruption are the result of equipment failures, power system
faults and control malfunction. They are characterized by their duration as the voltage magnitude is
always less than 10% of the nominal. The duration of an interruption can be irregular when due to
equipment malfunction or loose connections. The duration of and interruption due to a fault on the
utility system is determined by the utility protective devices operating time.
Voltage interruption is a large decrease in RMS voltage to less than a small percentile of the nominal
voltage, or a complete loss of voltage.
Momentary interruptions can cause absolute voltage loss, and they are normally the result by utilities
to clear transient faults on systems. Sustained interruptions during over one minute are normally
caused by permanent faults or scheduled downtime
