AVR Generator Mecc Alte SR7-2G

Description

Mecc Alte SR-7-2G AVR Generator

This AVR is compatible with Mecc Alte three-phase generators.

The SR7 AVR for the Mecc Alte generator is a thyristor-type automatic voltage regulator, controlled by half-wave phase control, and forms part of the excitation system for a brushless generator. In addition to regulating the generator voltage, the AVR circuits include underspeed protection and loss-of-detection protection to ensure safe and reliable control of the generator. The build-up of positive voltage from residual levels is ensured by the use of high-performance semiconductors in the AVR’s power circuits. It is connected to the main stator windings and the field windings of the exciter to provide closed-loop control of the output voltage with load regulation of +/- 1.5 per cent.
