AVRAutomatic Voltage Regulator is an instrument which is installed in electrical substations in order to control the output voltages of the transformers. It controls a motor driven on load tap changer and displays voltage, tap, and current and power factor on seven segments LCD.
Some of the AVR Main features are as follow:
Voltage Regulating Relay KT30 Series Micro processor Controlled
Line drop and Z compensation
Voltage setting remotely controllable (3 load shedding inputs and 4-20 mA input signal)
Internal computation to minimize circulation current of parallel transformers (parallel card is not required, only in KT30P series)
Basic controls such as auto/manual, individual/master/parallel, manual tap rising, and manual tap lowering etc. (only in KT30T series)
