Product Description

GDBC-901 High Quality 3 Phase Transformer Turns Ratio Vector Group Tester TTR Tester


Introduction:1. GDBC-901 Three Phase Transformer Turns Ratio TTR Tester is designed according IEC76-1 and IEC60044. 
2. GDBC-901 Three Phase Transformer Turns Ratio TTR Tester could be applied to test the turns ratio and group vector of single or three phase transformer. 
3. Also the connection group of GDBC-901 Three Phase Transformer Turns Ratio TTR Tester could be calculated with the ratio. 
4. All parameters are measured in one test for three phase transformer.

Functions:

• The voltage ratio measurement for three or singe phase transformer 

• The group vector measurement for three phase transformer.

• The polarity measurement for single phase transformer or CT/PT

• Voltage ratio error calculation

• Current transformer ratio measurement

• Excitation current measurement in ratio testing

• Reproduction the AC test voltage from power source to reduce the effects of bad power source

• Save the test results in the memory internal the tester

• Print the test results by micro printer

• Reverse connection detect unit to prevent the high voltage injected to operator

• Over current protection unit integrated in software and hardware

• Upload the test results to PC by RS232 and make word report by software
