  •     Power transformer is a kind of electrical equipment in electric system, it has equipped with multiple relay protection devices to ensure the transformer’s reliable operation, such as gas protection, backup protection and differential protection etc. Gas relay is an important executive component of gas protection, but it buried many hidden troubles for the grid security due to backward testing equipment and neglected calibration of gas relay in a long time. “RELAYTESTAR- WS100” Gas relay calibrator is a kind of brand new designed testing and calibrating device of gas relay. This calibrator can simulate the gas relay’s action mechanism in transformer internal faults, adopting a new generation of embedded control and high precise sensor measuring technology, to accurately detect the gas relay’s action velocity value and gas volume value. It has the features of high testing speed, high accuracy and well testing repeatability.
