LC-2KV Automatic Transformer Oil Tan Delta Tester
The LC-2KV automatic transformer oil tan delta tester designed and manufactured according to GB/ T5654-2007 "measurement of relative capacitance, tan delta and dc resistivity of liquid insulation materials". Used for measuring tan delta and dc resistivity of insulating liquid dielectric such as insulating oil. Integrated structure. Internal integration of tan delta oil cup, temperature controller, temperature sensor, tan delta test bridge, ac test power source, standard capacitor, high resistance meter, dc high voltage source and other main components. The LC-2KV oil tan delta tester is equipped with a 5.7 inch TFT pure color LCD touch screen and a English menu. The test results can be stored and printed out automatically. The operator can use it skillfully without professional training.
