Transformer Capacitance & Dissipation Factor Tan Delta tester
I. Summary
Tan Delta Test Set is a basic method in insulation test and effectively detect damp, degradation and partial defect of insulation of electrical equipment. This method is widely used in electric manufacturing, electric equipment installation, connection and preventive test. Measurement on dielectric loss of transformer, mutual inductor, reactor, capacitor, bushing and arrester is the most basic method to test their insulation property. It features strong anti-interference capacity, high test speed, high precision, automatic digitization and easy operation.
