Fault Passage( sensor)Indicator. FPI. ||Uses and Working

Fault Passage Indicator.

In other words it is also called as:-

Fault sensor indicator.

Line fault Indicator.

A fault indicator is a divice which provides visual or remote indication of a fault on the electrical power system.It is also called a faulted circuit indicator.(FCI).

It is used to detect fault and its location by the use of RSU of overhead and underground electrical lines fault.

RANGE:-

Short~Circuit Trip Current (Phase to Phase): Adjustable: 100/200/300/400/500/600/700/800/900/1000/1100/1200 A (110%) **

Earth-Fault Trip Current (Phase to Ground) : Adjustable: 10/20/30/40/60/80/100 A (¢10%) **

Short-circuit Response Time: Adjustable: 40/60/80/100/120/160/200/240 ms (+-100mSec)

Earth Fault Response Time: Adjustable: 40/60/80/100/120/160/200/240 ms (+-100mSec)

FEATURES:-

Programmable Earth fault pickup level (wide range 10A to 100A)

Indication of earth-fault by blinking of Earth-fault LED

Programmable response delay for Earth-fault

Up-to Two potential free contacts to indicate earth»fault. (remote indication for SCADA)

INSTALLATION EQUIPMENT:-

By the help of spring clamping rod the FPI Fault Passage Indicator can be installed in the live conductor..

RSU (Remote Switching Unit):-

See in the figure below 3 indicators can be installed in 3 phases if there is no fault then in the SCADA workstation and the indication should we shows green colour or no Fault.

If there is Fault in the line ,then Fault current flows in the conductor ,which occours the FPI gives signal to the RF GSM RTU and circuit breaker (CT) trips and the RF GSM RTU gives signal to SCDA workstation then through massage and calls the Fault information and location should be send to predifined lineman or substation..

The Falult Passage Indication can be installed in overhead lines as well as underground cables.

Why we can use FSI?

# With the help of fault passage indicator the exact fault location should we traced.

#It saves times.

#It saves manpower.

# It saves manpower so it can also save money.
