RSJS-M Transformer Capacitance Meter /Tan-delta Tester
Dielectric Loss Measurement is very basic insulation testing method which can effectively found the deterioration damp deterioration of electrical equipment insulation, as well as local defects. In electrical manufacturing, electrical equipment installation, transfer and preventive tests are widely used. Measuring dielectric loss of transformers, CT/PT, reactors, capacitors, and bushings, surge arresters and other is the most basic measure of its insulating properties. RSJS-M tan delta tester breaks the traditional bridge measurement method, using variable frequency power supply technology, using SCM, and modern electronic technology for automatic frequency conversion, analog / digital conversion and data operations. With strong anti-jamming capability, fast test speed, high precision, automatic digitization, easy to operate; use switching power supply, 45Hz and 55Hz pure sine wave output, automatic apply voltage, providing a voltage up to 10 kV; automatically filter 50Hz interference, suit forsubstation and other strong electromagnetic interference field testing. Widely used in the power industry transformers, CT/PT, bushings, capacitors, surge arresters and other dielectric loss measurement equipment.
Product Features
1.The tester adopts complex current method, which measuring capacitance, dielectric loss, and other parameters. High accuracy of test results, easy to realize automated measurement.
2.The tester adopts frequency technology to eliminate the scene 50Hz frequency interference, even under the condition of strong electromagnetic interference, can get reliable data.
