Overview

The gas relay calibrator is a tester device that specializes in verification of gas gas relays. The gas relay calibrator is a detection check device for the detection of the Vaste Relay Flow Period Value, Cable Point Value, and Sealing Pressure Value. Gas Relay Calibrator is suitable for more than 90 of Gas Relay checks in

Gas relay is also known as gas gas relay, is a protective unit in an oil immersion transformer, mounted in an oil pipe under transformer oil pillow. The gas relay detector is a dedicated gas relay pressure release valve calibrator device for the gas relay value, a capacity value, and sealing pressure value, and the gas relay tester uses a microcomputer control technology, and the gas relay tester is detected by detecting a high-precision pressure sensor. When the gas relay tester simulates the internal failure of the transformer, the gas method of the gas relay tester is calculated to calculate the flow rate value to achieve the detection of gas relatives, the Gas protection action value, the gas relay calibrator adopts the fine container combined with the US MCC's micro Press the precision sensor, detect the inside of the gas relay to exclude the liquid volume method to calculate the light gas capacity value

Product description

Earth ground resistance tester is a high-precision testing instrument used in various fields such as substations to test grounding resistance and related parameters.The instrument is of an integrated structure, with a built-in frequency conversion power supply module, and the output power supply is continuously variable in frequency. The frequency can be changed to 45Hz or 55Hz, the high-speed processor core is built in, and the high-end digital filtering technology is adopted, thus effectively avoiding the interference of power frequency electric field to the test and fundamentally solving the difficult problem of accurate measurement under strong electric field interference.
