Application:

SES-12 type Voltage Regulator is a compact, medium power, panel mounted a Automatic Voltage Regulator. The regulator when applied within its input and output ratings is designed to give excellent performance with LT & HT AC generators upto 25 MVA rating. The voltage regulator derives its input from the terminals of the AC generator and through appropriate potential transformer (in the case of HT AC Generators) and controls the exciter field excitation.

Features:

SES-12 has built in features to enable SOLO and PARALLEL operation of the AC Generator. The ‘ACCESSORY INPUT’ terminals, when interfaced with V Ar/pf controller, Auto Synchoroniser & GCUs based on PLCs enable the generator parallel itself automatically with the bus and later on maintain either pf or VAr constant.

SES-12 has built in settable protective features for under speed running and over excitation.
