Automatic voltage regulator

It is Automatic voltage regulator for driving OLTC (On Load Tap Changer). It maintains proper voltage using LDC (Line Drop Compensator) and Z-compensation function considering load characteristics. Tap adjustment device with built-in DVM (Digital Voltmeter) function allows effective voltage control upon sudden load change.

It is Automatic voltage regulator for driving OLTC (On Load Tap Changer). It maintains proper voltage using LDC (Line Drop Compensator) and Z-compensation function considering load characteristics. The OLTC can operate between up to eight transformers in parallel without additional equipment.

It is Automatic voltage regulator for OLTC (On Load Tap Changer,) drive, which allows voltage control according to load characteristics. Up to 8 transformers can be operated in parallel without additional equipment. With IEC 61850 communication function, it is suitable for digital substation.
