Leroy-Somer Alternator R150 AVR of Generator Set

1 - GENERAL DESCRIPTION The Automatic voltage regulator (AVR) is a compact, high performance encapsulated unit. The AVR incorporates latest technology and efficient semiconductor to achieve a high degree of miniaturization when applied to 3Ø and 1Ø AC brushless generator within its input and output limits, the unit offers excellent reliability. The AVR supplies DC excitation to the exciter field of a   brushless generator   to keep the terminal voltage within close limits from NO-LOAD to FULL LOAD. The recovery time on sudden loading is likely to be around 0.5 sec. to recover 98% of the rated voltage. Please note that the transient performance like voltage dip and recovery time are mainly decided by the generator and exciter design parameters. Best performance from the regulator can be obtained by keeping full load excitation around 60V DC. The generator employs true average sensing circuit, dV/dt snubber and special filters circuits to cope with NON-LINEAR loading li...
