Product Description

Heterodyne Anti-Interference Dielectric Loss Tester

Darui Electric recommends:

The heterodyne fully automatic dielectric loss tester is a high-precision testing instrument used in power plants, substations, and other field or laboratory settings to measure the dielectric loss tangent and capacitance of various high-voltage power equipment. The instrument features an integrated structure, incorporating a dielectric loss test bridge, a variable frequency voltage regulating power supply, a step-up transformer, and an SF6 high-stability standard capacitor. The test high-voltage source is generated by the internal inverter and stepped up by the transformer for testing the test object. The frequency can be changed to 45Hz or 55Hz, 55Hz or 65Hz, using digital notch technology to avoid interference from the power frequency electric field, fundamentally solving the problem of accurate measurement under strong electric field interference. It is also suitable for testing with generator power supply after a complete power outage. The instrument can be equipped with an insulating oil cup to test the dielectric loss of insulating oil.

Tester Features

◆ Simple operation, Chinese display, printing

◆ Convenient to use, no conversion needed

◆ The heterodyne dielectric loss tester comes with built-in high voltage, strong anti-interference capability, and short test time

Tester Characteristics

1.	Due to the adoption of frequency conversion technology, accurate measurement under strong electric field interference is ensured.
2.	The instrument uses a Chinese menu operation, and the microcomputer automatically completes the entire measurement process.
3.	The instrument is also suitable for measuring the tgδ and capacitance of high-voltage electrical equipment in workshops, laboratories, and scientific research institutions; it is more convenient, simple, and accurate for testing the dielectric loss of insulating oil.
4.	The instrument can use positive or reverse connection methods to measure high-voltage electrical equipment that is ungrounded or directly grounded. It can also measure the tgδ of capacitive voltage transformers and the capacitance of main capacitors C1 and C2.
5.	The instrument is equipped with a high-voltage step-up transformer and incorporates 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.
