Oil Dielectric Loss Tester RSJS-III Anti Interference Dielectric Loss

Anti-interference dielectric loss measuring instrument is a high accuracy instrument for power plants, transformer substations and so on to conduct full-automatic measurement of dielectric loss tangent value and electric capacity of various high voltage electrical equipment. Frequency conversion technology ensures accurate measurement under strong electric field interference. Chinese menu operation has been added to the instrument which has one-through operation. Microcomputer can automatically complete the measurement of the entire process. It is the most ideal dielectric loss measuring equipment now. The instrument is applicable to measure tgδ and capacity of high-voltage electrical equipment in workshop, laboratory, scientific research institution, etc.; It makes insulating oil loss test more convenient, simple and accurate.

It measures the capacitance and dielectric loss factor (tgδ) of high voltage electric device. It is integrated structure, built-in dielectric loss test bridge, variable frequency adjustable power supply, boosting transformer and SF6 standard capacitor. It is widely used to test the transformers, bushings, capacitors, arresters and other equipments in the power industry.

High voltage source is generated by internal inverter of the instrument, which is used for testing test object after transformer boost. If adding a insulation cup and temperature control device, dielectric loss of insulating oil can be tested.
