Portable Transformer Turns Ratio Testing Equipment 3 Phase TTR Tester

GDBC-901 Portable Transformer Turns Ratio Testing Equipment 3 Phase TTR Tester

Introduction:

The Portable 3 Phase TTR Tester is designed and made as per IEC 60076-1 Power transformers - Part 1: General and IEC 60044.

It's applied to measure the voltage ratio of three or single phase transformer.

What test items can be completed by GDBC-901 Portable Transformer Turns Ratio Testing Equipment 3 Phase TTR Tester?

1) The voltage ratio measurement of three or singe phase transformer.

2) The group vector measurement of three phase transformer..

3) The polarity measurement of single phase transformer or CT/PT (CT that knee-point voltage should be more than 80V).

4) Voltage ratio error calculation.

5) Voltage ratio range calculation of three phase transformer.

6) Current transformer ratio measurement.

7) Excitation current measurement in ratio testing.

Other Functions:

1) GDBC-901 3 phase TTR tester can save more than 200 group test results in the memory internal the tester.

2) After completed the measurement, you can print the test results by build-in micro printer.

3) Reverse connection detect unit to prevent the high voltage injected to the operate.

4) Over current protection in test voltage.

5) Upload the test results to make word report by RS232 interface.
