CableTroll® 2310Fault Passage Indicators for underground cables (6-36kv)

Functional Description

CableTroll®2310 series fault Indicators is a complete system for indication of phase to ground faults in underground 6-36 kV MV cable networks The earth fault sensor, which is a CT (current transformer), will measure the imbalance in the feeder in the case of an earth fault. All indicators located between the feeding transformer and the fault location will indicate.

The system consists of : �� Indicator housing with electronics and battery �� CT, Summing transformer

Trip level for earth fault detection is adjustable in the range from 5-220A.

The programming is done by altering the dipswitches located inside the main indicator hous-ing. Timer reset of indication is programmable to 2, 6, 12 or 24 hours.

Battery lifetime is estimated to 10 years of standby or 1500 hours of indication.
