Transformer Turn Ratio Tester
Transformer Turn Ratio Tester HYBC-901B is an instrument used ratio and phase angle measurement of power transformer and voltage transformer. The tester inject three-phase voltage to the primary side of transformer and measure the inducted voltage from secondary of transformer and then calculate the turns ratio, voltage ratio, phase angle difference between primary side to secondary.
