High Voltage Regulating Transformer

● High Voltage Regulating Transformer Main features

▶The overall device has a large capacity, low loss, small size, and is easy to install and maintain;

▶Automatically adjust the gear of the three-phase on load tap changer by tracking voltage changes, with reliable operation and high voltage adjustment accuracy

▶The voltage reference, action delay, allowable range, and frequency limit can be adjusted as needed, and the parameter settings are flexible and convenient;

▶Display the number of gear actions and current gear of the SVR on load tap changer, with indications for the highest and lowest gear

▶Equipped with gear upper and lower limit protection, action time limit function, effectively improving the reliability of the product

▶The controller has over voltage and under voltage protection functions. When the line is in an over voltage or under voltage state.the controller automatically locks; Ensure safe operation of on load tap changers

▶The controller adopts industrial grade control chips, which have high reliability, strong anti-interference ability, and can adapt to harsh outdoor environments;

▶The  High Voltage Regulating Transformer Main features Equipped with RS485 communication interface, the controller's parameters can be viewed and modified within 30 meters from the installation point through wireless communication module.

▶Cloud or SM card remote control can also be added.
