ZC-202A can mainly do two kinds of transformer test:         1:   No-load test is carried out on the low-voltage side of the transformer. During the test, the high-voltage side (13.8kV) terminal of the transformer is opened, and the voltage is added on the…

       1. What is automatic anti-interference dielectric loss tester        Automatic anti-interference dielectric loss tester is a high-precision instrument for measuring the dielectric loss tangent value and capacitance of various high-voltage power equipment in power plant and substation.The frequency conversion technology can ensure the accurate measurement under…

        About the new tester, I'd like to introduce the capacitive voltage transformer tester PTA-2000C for your reference.          PTA-2000C  can be used for VT,CVT,CCVT tests and our company is the only one manufacturer in local market.          It meets the following…

        One Malaysia customer come to our company yesterday and order the CT PT analyzer CTA-1000C.           Our engineer help the customer compare CTA-1000C CT tester with Omicron device and get very good results. This customer is professional and meticulous.     

       I'd like to share a piece of good news with you:         Today, my colleague went to the airport to pick up a foreign customer to visit our company's products. This customer came to our company to see the ct tester . We know…

      The main purpose of the intelligent transformer calibrator is to verify the technical performance of voltage transformers and current transformers used in the field or in the laboratory. In order to achieve this, the intelligent transformer calibrator must form a complete transformer calibration device with the relevant…

CTA-1000 variable frequency transformer integrated tester is a test for transformer: CT volt-ampere characteristics, error curve, ratio, polarity, demagnetization, secondary load, angular difference, ratio difference, transient PT excitation, Multi-functional field test instrument designed with parameters such as ratio, polarity and secondary load function. The frequency conversion transformer tester is based on…

      The CT analyzer automatically and accurately determines all relevant current transformer values and compares the results to selected standards.       With the push of a button, the current transformer can be evaluated in seconds based on IEC, IEEE or national/custom criteria.       It is a…
