• RD40 Density Transmitter The RD40 density transmitter is used to monitor the temperature, pressure and density of the gas in sealed tanks, and the functional parameters meet the requirements of the National Grid "QGDW123554-2023 Smart substation technical specification Part 4: Digital remote transmission meter" standard. It can be used in the new substation and the renovation and upgrading of existing substation. More+
• TR-80-R Intelligent Buchholz Relay Intelligent gas relay is a basic device applied to oil immersed transformer. It can monitor the accumulation of gas generated by leakage current, arc, flashover and other faults in the transformer in real time, and send out alarm signals when the gas reaches a certain amount; In case of serious internal fault of transformer (such as interturn short circuit, etc.), use the oil flow surge phenomenon generated at this time to trigger contact connection, and quickly lock the main circuit of transformer to protect the transformer.

• VDA-03 Gas Density Relay Calibrator The VDA-03 Gas Density Monitor Calibrator is an intelligent, fully automatic calibration instrument that uses advanced embedded microprocessors to test the performance of Gas Density Monitors for SF6, SF6/N2 hybrid and SF6/CF4 hybrid gases. The device has two working modes: zero-pressure mode and working pressure modes. Working pressure calibration mode tests the accuracy of GDM from the rated filling pressure to zero, while zero pressure mode starts from zero and rises to the rated pressure. This portable calibration instrument provides great convenience for the operation, testing, calibration and maintenance of electrical products. More+
