Variable frequency dielectric loss tester is a very basic method in insulation test. It can be found that the whole insulation of electrical equipment is deteriorated by damp, as well as local defects and so on. It is widely used in electrical manufacturing, electrical equipment installation, handover and preventive test. The measurement of dielectric loss of transformer, transformer, reactor, capacitor, bushing and lightning rod is the basic method to measure their insulation performance. The dielectric loss tester breaks through the traditional bridge test method, uses the frequency conversion power supply technology, uses the single chip microcomputer and the modern electronic technology to carry on the automatic frequency.
The dielectric loss tester breaks through the traditional bridge test mode, adopts the frequency conversion power technology, uses the single-chip microcomputer and the modern electronic technology to carry on the automatic frequency conversion, the analog-to-digital conversion and the data calculation; achieves the anti-interference ability to be strong, the test speed is fast, the precision is high, the full-automatic digitization, the operation is simple; the power supply uses the high-power switch power supply, outputs the 45Hz and the 55Hz pure Xuan wave, adds automatically Voltage, can provide a maximum voltage of 10kV.
It can automatically filter out the interference of 50 Hz. It is suitable for the field test of large electromagnetic interference, such as transformer, transformer, bushing, capacitor, arrester and other equipment in the power industry.
