Able to measure buchholz relay’s flow velocity value and action gas volume value RELAYSTAR-WS300 Buchholz Relay Test Bench is a newly designed test and calibration equipment for buchholz relay. This test bench can simulate buchholz relay action mechanism inside transformer when internal faults occur. Power transformer is very important in power system electrical equipment. In order to ensure the reliable operation of transformer, multiple fast protection devices are installed, such as buchholz relay, backup protection, differential protection. Buchholz relay is an important executive component of gas protection. But for a long time, due to the detection equipment fall behind and neglect of buchholz relay test, leaving serious hazards for power grid security. RELAYSTAR-WS300 Buchholz Relay Test Bench is a newly designed test and calibration equipment for buchholz relay. This test bench can simulate buchholz relay action mechanism inside transformer when internal faults occur. A new generation of high-precision sensors embedded control and measurement technology is adopted for RELAYSTAR-WS300 Buchholz Relay Test Bench, which tests the buchholz relay’s flow velocity value and action gas volume value accurately.
