EDQT-608B Portable Gas Relay

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 utilizes superior domestic microcomputer control technology, calculates flow rates by detecting high-precision pressure sensors, simulating internal transformer faults, and using 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 utilizes a precise container paired with a U.S. MCC Company's micro-pressure precision sensor to measure the volume of liquid excluded from the gas relay, thereby calculating the light gas volume value.
