TDT Automatic Three Phase Transformer Insulation Power Factor Tester
Product Description
TDT Automatic Three Phase Transformer Insulation Power Factor Tester is used to measure electrical loss tangent ( ) and capacitance of all kinds of high voltage electrical equipment in power plants, substations, laboratory, etc.
TDT Transformer Insulation Power Factor Tester is composed of a dielectric loss test bridge, a variable frequency power supply, a step-up transformer and a SF6 high stability standard capacitor, it is integrated structure.
It can also supply high voltage source for testing.
Frequency can be changed to 50Hz, 47.5Hz\52.5Hz, 45Hz\55Hz, 60Hz, 57.5Hz\62.5Hz, 55Hz\65Hz; thus, it can avoid interference of power frequency.
