??What is the significance of measuring dielectric loss tangent tg? The dielectric loss tangent value is also known as the dielectric loss factor or simply dielectric loss. Measuring the dielectric loss factor is a high sensitivity test project, it can be found that the insulation overall moisture, electrical equipment insulation deterioration as well as small volume test equipments through and not through local defects. Due to measuring dielectric loss factor to reflect these defects with high sensitivity, the electrical manufacturing and electricity EIR and preventive tests have been widely used. Transformers, generators, circuit breakers and other electrical equipment, the dielectric loss test procedures have made provisions. ??The present status and technical difficulties of dielectric loss tester With the development of dielectric loss tester technology, dielectric loss tester intelligent being replaced in power systems are widely used QS1 Bridge. The new generation of dielectric loss tester built-in step-up device and standard capacitor, and simple operation, the data is accurate, easy to read test results etc. Although the dielectric loss test technology has developed rapidly, but compared with international standards, in many respects, there is still a big gap, the gap is mainly manifested in the following aspects: 1) Anti-interference ability 2) The opposition method of test accuracy Himalayal,always by your side.
