Polymer Insulated Fault Interrupters for 2 5 .8kV Overhead Line
1. Introduction
This is installed on feeder, wire or service entrance of consumer, in the branch point of below 16MVA
load capacity. When over load or fault is occurred, it minimizes the damage and prevents the fault
expansion by opening only the fault section with the cooperation of upstream protection equipment
(CB, Recloser). Easy operation status monitoring is available by built-in load current indicator and
live line status indication.

Polymer Insulated Fault Interrupters for 2 5 .8kV Overhead Line
3. Function and Characteristic
When the fault current higher than Min. pickup current flows, automatic breaking is available
according to the T-C Curve and if the upstream protection equipment is opened first it is spring
charged regardless the T-C Curve. This is used for frequent lightning place, industrial line. the
following functions are provided.
3.1. Over-current Trip function
This interrupter detects over-current and separates the fault section from the system when the
upstream device protection equipment is opening the line. Besides, detects over-current and
cooperates with the upstream protection equipment. OCR Trip, OCGR Trip function is provided.
3.2. Cold Load Pickup function
Restrain the over-current Trip function and charge Trip function to prevent the malfunction by
inrush current produced during the closing or when becomes live line by upstream protection
equipment closing from dead line status.
After the interrupter is opened, if the interrupter is closed exceeding the 'Outage Time', this
function is not operated, if the interrupter is closed after the 'Outage Time' this functions operates
normally. Under the Interrupter closed condition, the line becomes dead line by upstream
protection equipment and if the line becomes live line by reclosing within 'Outage Time' the Cold
Load Pickup function does not operate.

3.3. Line current and Live line indication
Each phase currents (A,B,C,N) are displayed on LCD of control box and Lamp that indicates the
line status of source side (phase A) is provided.
3.4. Easy function setting
Min. pickup current, over-current lock current and other all setting can be set in LCD menu of
control box.
3.5. Battery discharge prevention

4. Control Setting
The setting method of Interruptor control is the same as following.
4.1. Minimum Pickup Current
Easy Min. pickup current setting is available through control LCD menu.
4.1.1. PHASE Min. Pickup Current Setting
PHASE Min. Pickup Current is 2~3 times of Max. Load Current.
Contract ( kW )
22 .9( kV ) × 3
× ( 2 ~ 3 times ) = PHASE Min . Pickup Current
4.1.2. GROUND Min. Pickup Current Setting
Malfunction can be caused if Unbalance rate of three phase is big and GROUND Min. Pickup
Current is smaller than Load Current. Therefore, GROUND Min. Pickup Current shall be set in
50% of PHASE Min. Pickup Current.
4.2. Cold Load Pickup Setting
Inrush Time and Outage Time can be set easily in LCD menu of control. Default value of Inrush
time is 0.5 sec. and Default value of Outage Time is 3.0sec.
5. Operation description, function test, operation method
5.1. Operation description
5.1.1. When the fault current is over than Min. pickup current the upstream protection device
does the delay operation, mostly the fault is removed directly by the interrupter because the
CONTROL RESPONSE TIME of interrupter is fast. Sometimes the upstream protection
equipment removes the fault depending on its setting.
5.2. Operation function test
This interrupter is set and tested completely before the delivery.
5.2.1. Min. Pickup Current test
The Min. Pickup Current test has ±10% accuracy.
5.2.2. Cold Load Pickup test (0.5sec SET status)
Apply current above the min. pickup current. If the current is interrupted within 0.45sec. it
doesn't TRIP.

-Does the connecting loop of opening side
receive too many strength?
-Is the min. pickup current set according to
the load capacity?
It can be opened
frequently if the fault
current flows
continuously.
-Is the battery terminal closed?
-Is the control cable connected?
-Is the battery discharged?
-Is the fuse in the control box is cut?
When the battery voltage
is under DC24V, it is
charged after 48hours of
AC220V power input.
[If the battery is
completely discharged it
shall be changed]
It does not close
automatically.
* Note: We don’t provide the rope.
Please contact us in case of other problems.
