NRZBJ Turns Ratio Tester Calibrator
NRZBJ Turns Ratio Tester Calibrator (also known as Turns Ratio Tester Calibration Device), it is used to calibrate the transformation ratio accuracy, resolution and group (including Z-type group) of transformer turns ratio tester with accuracy of 0.05 and below. This device is divided into two parts: standard three-phase PT and seven-plate inductive voltage divider. The standard three-phase PT is used to verify the group test function of the transformer turns ratio tester, including the Z-shaped group, and there are three voltage ratio options at the same time; the seven-plate inductive voltage divider is used to verify the transformation ratio accuracy and resolution of the transformation turns ratio tester, can also be used as an inductive voltage divider alone.
