We are very pleased to receive good feedback from our customers regarding the use of the GDVA-405 CT PT analyzer! GDVA-405 CT PT Anayzer is designed as per IEC60044-1,IEC60044-2,IEC60044-5,IEC60044-6 and IEC61869. It can measure all kinds of CT and PT. The accuracy is 0.02%(typical),0.1%(Guarantee).

The error of current transformers is divided into ratio error and phase angle error:The ratio error is the current value indirectly measured through the secondary circuit (KeI2 minus the percentage of the actual value of the primary current to the actual value of the primary current). That is, the p

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
