OVERHEAD FAULT INDICATORS

(Clip-On Fault Passage Indicators)

COMMUNICATION / LED INDICATION TYPE

FPSC - SI 1

FPSC-WFI-COM1

FPSC-WFI-COM2

FEATURES

● Both Flag and LED indication

The fault can be indicated by both flag and LED lamps.

 

● Communication

The overhead type fault indicator can transfer the fault information wirelessly, and communicate with the sub transmitter by sending and receiving signals.

 

● Trip current self-adjustment.

The fault indicator can adjust the phase to phase and phase to earth trip current as per different load current, the minimum current surge should be 120A.

 

● Entirely sealed structure.

The fault indicator is sealed using epoxy resin, the whole structure can withstand aging effects for a long time, like high temperature, and high humidity. The outside shell is made of UV resistant material, it can sustain exposure to high ultraviolet environment for a long time.

 

● Eliminate misact phenomenon.

Eliminate the reverse feeding misact based on the difference in features of reverse feeding current and normal fault current.

 

● Convenient operation means.

The fault indicator can be installed to the overhead line or underground line directly by a hot-stick with tool.

 

● Advantage trip criteria.

The current surge ΔI and the fault current duration time Δt is accordance with the Time inverse curve.

 

● Long life batteries.

The industry battery is used for power supplying and battery monitoring. The battery life is 8 to 10 years.

 

● High earthing fault detection ratio.

The signal source will reject a current to the earthing fault circuit, it can increase the earthing fault detection ratio to 90%.
