  • The digital controlled KPVA17x range provides precision (1.0%) reverse reactive power and reactive 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. As standard the auxiliary voltage is taken from the unit monitored voltage input. A separate AC or DC auxiliary voltage is optionally available. Special features: -Precision Generator Reactive Power 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 Bornika is the exclusive representative of megacon company, in purchasing , sales, consulting and distribution of industrial equipment including generators Controllers and Guards.

More details
  • :
  • KPVA171C 3-wire configuration. Reverse power relay (R1) is used to trip the generator breaker. The overload relay (R2) can be used for non-essential load release or as start signal to standby generator etc. A wide range overload hysteresis can be set to enable R2 to be used for non-essential load to be reconnected or as standby generator stop signal. Relay R3 is intended for notification of a reverse power condition, or can be used for local indication, as input to an alarm system etc. R1and R3 will latch after trip. KPVA174C Similar to KPVA171C, but for 4-wire configuration. KPVA171F 3-wire configuration. The unit is similar to KPVA171C, but R3 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. KPVA174F Similar to KPVA171F, but for 4-wire configuration. KPVA176A 3-wire configuration. The unit is similar to KPVA171C, but also includes an analogue output proportional to the generator kVAr-load. KPVA177A Similar to KPVA176A, but for 4-wire configuration. KPVA176F 3-wire configuration. The unit is similar to KPVA171F but also includes an analogue output proportional to the generator kVAr-load. KPVA177F Similar to KPVA176F, but for 4-wire configuration.
