XHBB128B tests the turns ratio or voltage ratio of the operating transformer, and can check the correctness of the turns ratio of the transformer, the condition of the tap changer, whether the transformer is short-circuited between turns, and whether the transformer can operate in parallel. The operation is simple and intuitive, using three-phase precision inverter power supply, the test is fast and the accuracy is high.
Features:
1. It is suitable for a wide range of transformers, especially suitable for the measurement of Z-type transformers, rectifier transformers, grounding transformers, electric furnace transformers, phase-shifting transformers, balanced transformers, etc., with the most comprehensive measurement parameters.
2. Automatically measure the transformer ratio, error value and tap position of the tap changer.
3. Adopt 7-inch high-definition color touch screen LCD, modular display,
4. The instrument has both printout and U disk interface, and can also be equipped with RS232 interface to facilitate paperless office.
5. Use a multi-functional engineering plastic box that is cold and temperature resistant, sealed and waterproof, anti-fall and shock-proof, to facilitate field testing.
