Fault Current Indicator. Faulted circuit indicators eaton s cooper power series faulted circuit indicators offer multiple types of fcis ranging from basic circuitry models in the delayed reset style to the more sophisticated circuitry of the test point reset and electrostatic reset types. Industry analysis of the fault current indicator chaobo automation technology co ltd.
The fault current indicator are connected to high voltage and low voltage cables and comprise of auto switchgear circuit breakers protection equipment and motor magnet switch. Industry analysis of the fault current indicator chaobo automation technology co ltd. To be independent from the load current some fi s look at the e field to check the voltage directly.
Faulted circuit indicators eaton s cooper power series faulted circuit indicators offer multiple types of fcis ranging from basic circuitry models in the delayed reset style to the more sophisticated circuitry of the test point reset and electrostatic reset types.
To be independent from the load current some fi s look at the e field to check the voltage directly. The main purpose of these fault current indicator is to control distribute break as well as convert the power supply by entering the high voltage cable and then to the low voltage ones. Some fault indicators can block inrush current. To monitor the live line some fault indicators look only at the magnetic field caused by the load current.
