OEM Best Surge Voltage Test Factories – GDB-D Transformer Turn Ratio Tester – HV Hipot

General Information

GDB-D Transformer turn ratio tester is designed for three phases transformer in power system and especially for Z type winding transformer and other transformers with relatively large no-load current. The instrument is with wide range, fast testing speed, favorable repeatability, flexible date processing, convenient connection, perfect protection, easy learning and convenient operation.

Features

● Applicable to Z type winding transformer.
● Two output voltage can be optional and able to test transformers with relatively large no-load current.
● With wide range, the highest turn ratio may reach 10000.
● Automatically calculate the tap position.
● Fast testing speed which is only 18s for three phases
● Favorable repeatability.
● Automatically record 99 data at most.
● Flexible data processing which can search, print, transfer to U disk, delete and upload PC for testing.
● Having the protection function of transformer short circuit and turn-to-turn short circuit.
● The corresponding word will be displayed on the LED once there is short circuit .
● Computer can completely controls the whole process, record data and print test report.
● Built-in manual that can be consult occasionally.
● With small size and light weight.
