The anti-interference automatic dielectric loss tester is a high-precision instrument for fully automatic measurement of dielectric loss tangent and capacitance of various high-voltage power equipment at power plants, substations, and other sites.Dielectric loss insulation testing can effectively detect overall moisture, deterioration, and local defects in electrical equipment insulation, and is widely used in electrical manufacturing, electrical equipment installation, handover, and preventive testing.
II. Product Features:
1. Due to the use of frequency conversion technology, accurate measurement can be ensured under strong electric field interference.
2. This instrument uses a Chinese menu operation, and the microcomputer automatically completes the entire measurement process.
3. This instrument is also suitable for measuring tgδ and capacitance of high-voltage electrical equipment in workshops, laboratories, and scientific research institutions.
4. This instrument can measure ungrounded or directly grounded high-voltage electrical equipment using positive or reverse connection methods. It can also measure the tgδ of capacitive voltage transformers and the main capacitances C1 and C2.
5. This instrument is internally equipped with a high-voltage step-up transformer and adopts safety protection measures such as zero-crossing closing and lightning protection. During the test, it outputs high voltages of different levels from 0.5KV to 10kV, making operation simple and safe.
6. Can measure CVT type transformers.
