RVR-1 type single phase Automatic voltage regulator

 

RVR-1 auto step voltage regulator for feeder distribution network

 

++++ General

 

The RVR-1 type feeder automatic voltage regulator is actually a single phase oil immersed auto-transformer with RVR controller and gathering sampling of voltage &current signal, on load tap charger controlling device to achieve gird more efficient from adjust the load character by increase and decrease the voltage.

 

So This RVR is a transformer equipped with on load tap charger with RVR controller sampling voltage and current data and on load tap charger steps from current transformer and voltage transformer and limit switches.

 

++++ Main Features

 

+The RVR-1 regulate distribution line voltages from 10% raise (boost) to 10% lower (buck) in thirty-two steps of approximately 5/8% each. Voltage ratings are available from 2400 volts (60 kV BIL) to 34,500 volts (200 kV BIL) for 60 Hz and 50 Hz systems.

+With RVR type Smart controller, a self-developed technology, GPRS/GSM, Blue-tooth.

+With self-protection LOCK-OUT functions: Line fault, Overload, OverCurrent, Under-voltage

+With adjustable voltage datum and step scope limit, step draw delay, data setting.

 

++++ Standard Features

 

• Position indicator with ADD-AMP adjustment
