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%.
