NRBZC-Ⅲ Transformer Turns Ratio Tester

According to the IEC and related national standards during the production the user acceptance and maintenance test process of power transformers transformer turns ratio test must be done to effectively monitor the quality of the transformer so as to prevent short circuits open circuits and wiring error of the transformer internal failure or poor contact of the voltage switch. For this reason our company develops and produces a fully automatic turns ratio tester on the original basis according to the user's application requirements which makes the operation more convenient complete functions stable and reliable data and greatly improved testing speed. Adapt to the change of the test requirements of various sizes of transformer.

Characteristics and functions

● English menu prompt the operation is simple and convenient.
● Wide ratio measuring range: 1-9999.9
● Powerful function: not only can be used for single phase measurement and can realize three-phase winding automatic test connected groups can be chosen arbitrarily a complete measurement of AB BC CA three-phase variable ratio error line group parameters.
● High test speed: it only takes a few seconds to complete the three-phase measurement at the same time.
● After completing measurement the test power is automatically cut off.
● Set the data the measurement results are automatically saved can view the previous data.
● To test the on-load transformer only enter turns ratio once.
● Convenient to carry suitable for field operations.
