VAr Load Sharer for Conventional and Electronic AVR’s

  • Reactive load sharing
  • System voltage control
  • Relay based voltage control
  • Soft unload with breaker trip
  • 50 hour burn-in before test
  • Certified for marine use
The T4900 VAr Load Sharer is designed to control a generator operating in parallel with the grid, or a generator operating in parallel with other generators (which are also controlled by T4900 units).
The T4900 will continuously measure and compare the reactive current on the generator to an external DC reference signal connected to the “parallel line” input. The T4900 will increase or decrease the voltage of the generator (through the AVR) if it finds the reactive current level to be either too low or too high. Two built-in relays provide the increase and decrease pulses for the automatic voltage regulator (AVR). The strength (width) of the pulses is proportional to the voltage deviation. The E7800 Motorised Potentiometer can be used to adapt the contact pulses to a signal suitable for most AVR’s.
