Product Description

The EDQT-608B portable gas relay tester is a protective unit in an oil-immersed transformer. The gas relay tester is a specialized device for verifying the flow rate, volume, and sealing pressure values of gas relays. The EDQT-608B portable gas relay tester employs advanced domestic microcomputer control technology, calculates the flow rate by simulating internal transformer faults with high-precision pressure sensors and the instantaneous explosion pulse pressure method, to detect the heavy gas protection action value of the gas relay.

The EDQT-608B portable gas relay tester employs a precise container combined with a micro-pressure precision sensor from the U.S. MCC Company to measure the volume of liquid removed from the gas relay internally, thereby calculating the volume of light gas.
