Automatic Voltage Regulator AVR R450M for Leroysomer Generator
- Model Number: R450M
R450M AVR is powered by two auxiliary windings which are
independent of the voltage equal circuit. The power supply voltage
is rectified and filtered before being used by the AVR monitoring
transistor. With PMG excitation, a permanent magnet generator (PMG)
added to the alternator supplies the AVR with voltage.
On Application of load, the rotation speed of the generator set
decreases, when it passes below the preset frequency threshold the
LAM causes the voltage to drop by approximately13% or 25% and
consequently the quantity of active load applied is reduced by
approximately 25% to 45%, until the speed reaches its rated value
again. Hence the LAM can be used either to reduce the speed
variation (frequency) and its duration for a given applied load or
to increase the applied load probable for one-speed variation
