AVR

This AVR is suitable for brushless generators upto 320kVA of all makes like Kirloskar, Leroysomer, Marathon, Trident, Stamford. This AVR is a compact high performance encapsulated unit with latest technology and efficient Semiconductors to achieve a high degree of miniaturisation. This AVR contains a solid state buildup circuitry to ensure positive voltage buildup from very low residual voltages.

This AVR employs true average sensing circuit, dv/dt, snubbers and special filter circuits to cope with Non-Linear loading like Batter Chargers, DC drives etc. The AVR regulates the Line to Neutral of generator voltage and in addition to this it includes under speed protection to prevent the generator rotating parts from over heating due to over fluxing.

The recovery time on sudden loading is likely to be around 0.5 sec to recover 98% of the rated voltage.
