HJ standard voltage transformer is also called standard PT, precision voltage transformer, voltage transformer standard, calibration voltage transformer and voltage transformer standard, standard transformer and standard voltage transformer

It is mainly designed for the voltage transformer calibration standards of the basic power supply and production departments. Standard transformers are aimed at the calibration requirements of the measured transformers with secondary voltages of 100V, 100/V, and 100/3V.

Quasi-voltage transformer standard support: DL/T726-2013.

       HJ standard voltage transformer is used as the calibration standard of voltage transformer in the error test of the transformer. The standard voltage transformer is mainly for the basic power supply and

The actual needs of the production department are carefully designed and manufactured, and the technical requirements of high precision and high stability are completely extracted. The standard voltage transformer can be used for the secondary voltage of 100V, 100/V, and 100/3V.

According to the calibration requirements of the measured transformer, the standard voltage transformer can also produce the technical indicators of the inflatable standard voltage transformer and the dry-type standard voltage transformer according to the requirements.

     1. The standard voltage transformer is compact in structure, small in size and easy to carry;

       2. The standard voltage transformer does not require maintenance, wiring and operation are simple;

       3. The calibration requirements of the standard voltage transformer for the transformer under test with secondary voltage of 100V, 100/V, and 100/3V.
