AC CURRENT IMBALANCE PROTECTION

  • 2-level AC Current Imbalance Protection
  • True RMS measurement not affected by heavily distorted wave forms
  • 3 or 4-wire systems. Definite time trip delays
  • Total processing time less than 60mS
  • For use with 1A or 5A current transformers
  • DIN96 Slave Indicator (Scaled 0-40%In) with status LED’s (Optional)
  • Up to two individual very fast analog output signals (<50mS)< (Optional)
Description
KCC110E, KCC110G, KCC110Fx or KCC110GFx digitally controlled monitor and convert the three current transformer (CT) inputs into a signal proportional to the difference between the HIGHEST and the LOWEST input level.
The difference (imbalance) is displayed as a percentage of the CT rating. The standard scale range is 0 to 40%CT. The warning and alarm trip relays are settable over the same range.
Relay R1 is used for early warning. R2 (fail safe) can be used for generator breaker trip. R3 can be used for local indication, input to PMS, alarm system etc. Alarm trip must be sufficiently high to ensure that generator magnetization current does not cause tripping.
The alarm delay is to be set so that the initial inrush current have returned to normal level before the delay period elapses. The warning trip level and delay can be set as required to give early warning.
Fast response analogue output signal proportional to a range (KCC110Fx & KCC110GFx).
User settable trip levels and delays. Color of LED’s indicate alarm status. LED’s flash during count-down.
The “Pathfinder” (only on latching models) indicates the phase causing the trip by flashing pattern of the relevant LED.
