Product Description
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.
Feature/Function
1.RSJS-D adopts the negative current method to measure the capacitance, dielectric loss and other parameters. The accuracy of the test results is high and the automatic measurement is realized.
2.It dopts frequency conversion technology to eliminate 50Hz power frequency interference on site. Even in the environment of strong electromagnetic field interference, reliable data can be measured.
3.The instrument is easy to operate and the measurement process is controlled by a microprocessor. As long as the appropriate measurement method is selected, the measurement of data can be completed automatically under the control of the microprocessor.
4.Integrated model with standard capacitor and high voltage power supply, easy to test on site and reduce field wiring.
5.It has low-voltage shielding function of reverse wiring, grounding protection and electric shock protection.
