Product

The Product is automatic voltage regulator to operate the On Load Tap Changer(OLTC) on main transformer. It can control the voltage according to each load characteristics and can supporting parallel operation up to 8 sets of transformer without any additional devices and also, it can IEC 61850 Communication. So, This product is suitable for the digital substation.

Features
