Current Transformer Tester Introduction

The current transformer on-site calibrator is simple to operate, with intuitive readings and rapid measurements. It can reduce power consumption and labor intensity. It is small in size and light in weight, easy to carry and test on-site. The current transformer calibrator can be tested at 5% of the rated working current (voltage). Reference standards: JJG313-94, JJG314-94.

In addition, the company is also required to produce current transformer calibrators for testing S-class current transformers and current transformer calibrators with a secondary voltage of 100/3V. At this time, the current transformer tester can measure the error of the current transformer at 1% of the rated working current; during the testing process, the instrument can conveniently perform self-calibration at any time to ensure the accuracy of the instrument; key components use imported components with stable and reliable quality, which are widely used in measurement, power supply and other departments and transformer manufacturers, and are ideal instruments for transformer testing.
