The measurement error of the transformer is related to the impedance of the secondary circuit. The increase of the impedance will increase the error, and the accuracy will decrease. Therefore, the external impedance is a key factor in determining the exact level at which the current transformer oper

At the end of March, we received an export order for one set GDVA-405 CT PT analyzer. With the efforts of the production department, we have shipped GDVA-405 to the customer's freight forwarder yesterday.GDVA-405 Automatic CT PT Analyzer is used to test CT PT (220V-500KV,＞2.5VA,turns ratio＞1:1).
