Gr MAKE L.T.AUTOMATIC VOLTAGE REGULATOR / CONTROLLER

“Gr” make voltage stabilizers are manufactured by M/s. GLOBE RECTIFIERS, Faridabad, whose name is well known for reliability and continuous improvement in the field of Rolling Contact-type Automatic Voltage Controllers (Stabilizers), Silicon Power Rectifier Equipment and special purpose transformers.
“Gr” Make Rolling contact type Automatic Voltage controller are guaranteed for ‘FIVE YEARS UNCONDITIONAL’ and life at full load is 15-20 years.

Voltage fluctuation is a common phenomenon in every part of the country. Inspite of the best efforts, no state electricity board can ensure constant voltage to the customer because of long and inadequate distribution lines and irregular load pattern on Distribution Transformers. Automatic Voltage Regulator/ Controller is an equipment to obtain constant voltage from fluctuating supply System. The industrial units running round the clock usually face the problem of low and high voltage. 90% of industrial load is of motors. Electric motors draw considerably high current at low &high voltage. This higher current affects the electric motors in these ways:

• Higher current produce higher losses in Electric motors which cause premature failure of winding
• These higher current of electric motors also increase the losses of Cables, Switches, Transformer & other associated equipments.
• This Higher current of Electric motors require 15-20% higher setting of over load relay to avoid frequent tripping of motor’s starter. Higher setting of over load relays have very little safety margin against single Phasing and over loading conditions.

With the installation of the AVR/AVC and maintaining 390/400 Volts, the motor will operate smoothly drawing 15-20% lesser current and corresponding the relay setting can be reduced by 15-20%.In Case single phasing occurs, the relay will trip in 40-50 second. The motor can withstand the high current for this period and will be safe. Also, the relays, contractors, switchgears, etc. incorporated with the motor will be safe.
