I. General Information

GDB-D Transformer turn ratio tester is designed for single and three phase 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.

II. Features

• 1. Applicable to Z type winding transformer.
• 2. Two output voltage can be optional and able to test transformers with relatively large no-load current.
• 3. With wide range , the highest turn ratio may reach 10000.
• 4.Automatically calculate the tap position.
• 5.Fast testing speed which is only 18s for three phases
• 6.Favorable repeatablity.
• 7.Automatically record 99 data at most .
• 8.Flexible data processing which can search , print , transfer to U disk , delete and upload PC for testing .
• 9.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 .
• 10.Computer can completely controls the whole process, record data and print test report.
• 11.Built-in manual that can be consult occasionally.
• 12.With small size and light weight .
