Induction Voltage Divider HJF3

1. Usage

HJF3 type induction voltage divider is used for testing and calibration of voltage transformer

whose ratio is different from standard voltage transformer.

In general, the secondary load of standard VT is 0.2VA(100V) or 0.07VA(100/√3V); total exciting

power of primary and secondary is only 0.05VA (100V), so it will not give influence on accuracy when

connecting secondary of standard VT.

2. Technical Parameters

Customization is available.

Notice Points

1. Waveform of power source should be sine wave, and distortion should be less than 5%, and

frequency variation should be ±0.5HZ

2. Don’t have noxious gas or other dielectric in the worksite which will give influence on insulation

of voltage transformer

3. Don’t have heavy shaking at site

4. Should not have external strong magnetic field in the test site.
