The digital controlled KCVA17x range provides precision (1.0%) reverse reactive power and overload protection and monitoring of three phase generators. The unit measures the voltage and current true r.m.s. value, and accuracy is independent of any wave form distortion. The auxiliary voltage is supplied from the unit voltage input. A DC auxiliary voltage input is optionally available. Special features: -Precision Generator kVAr Load Protection, not affected by heavily distorted waveforms -Total processing time less than 50mS -3 or 4-wire systems. Definite time trip delays -2-level overload protection (F version) -Fast response analogue kVAr-signal output, <50mS -Wide range setting of overload contact hysteresis -Optional DIN96 Slave Indicator with status LEDs Bornika is the exclusive representative of megacon company, in purchasing , sales, consulting and distribution of industrial equipment including generators Controllers and Guards.

More Details
  • KCVA171C 3-wire configuration. Reverse power relay (R3) is used to trip the generator breaker. KCVA174C Similar to KCW171C, but for 4-wire configuration. KCVA171F 3-wire configuration. The unit is similar to KCVA171C, but R1 is not used for reverse power notification, but as Overload 2 trip relay. R2 and R3 are non-latching and have a 10% fixed hysteresis. KCVA174F Similar to KCVA171F, but for 4-wire configuration. KCVA176A 3-wire configuration. The unit is similar to KCVA171C, but also includes an analogue output proportional to the generator kVAr-load. KCVA177A Similar to KCVA176A, but for 4-wire configuration. KCVA176F 3-wire configuration. The unit is similar to KCVA171F but also includes an analogue output proportional to the generator kVAr-load. KCVA177F Similar to KCVA176F, but for 4-wire configuration.
