According to the relevant IEC standards, in the process of power transformer production and maintenance, the transformer ratio test is a must-do item, which can effectively supervise the quality of the transformer during delivery and use, and prevent the transformer from short circuit, open circuit, connection error, Internal fault or contact fault of the pressure switch.
TTR-I Single Phase or Three Phase Current Transformer Turns Ratio TTR Meter is designed according IEC76-1 and IEC60044, it is a multi-functional, easy operation turns ratio tester.
