This week we completed the production for GDVA-405 Automamtic CT PT Analyzer and already arranged the shipment to our customer yesterday.GDVA-405 Automatic CT PT Analyzer is used to measure CT PT(220V-500KV,>2.5VA). The test standards are IEC60044-1,IEC60044-2,IEC60044-5,IEC60044-6,IEC61869,IEEE C57

What's the principle of low-frequency method for measuring the excitation characteristics of current transformers?Excitation characteristic test is the most commonly used and effective method for detecting the performance of protective current transformers.The composite error of current transformers

GDVA-402 CT PT Tester is a full automatic transformer comprehensive tester.The tester can finish: CT/PT volt-ampere characteristic curve test, CT/PT Polarity test, CT/PT Transformation ratio test, automatically calculate error curve of any CT point.If you are interested in it,kindly contact us!Conta
