Operating instructions

The inductive voltage divider is mainly used in two states: as a voltage divider and

as a voltage proportionerThe two usage states are described below.

1.Use inductive voltage divider to calibrate voltage transformer (used as voltage divider)

When using the inductive voltage divider to calibrate the voltage transformer, connect

the line according to the above figure. Generally, the standard error of the inductive

voltage divider relative to the accuracy of the tested voltage transformer can be ignored.

The indication value of the tested voltage transformer can be directly read out from the

voltage transformer calibrator, and the error of the tested transformer can be calculated

after conversion to one time.If the primary voltage of the tested voltage transformer
