Product Description

IEC76-1 Automatic Three Phase Transformer Turns Ratio TTR Tester 

              

Introduction

GDBC-901 is applied to measure the voltage ratio of three or single phase transformer. All the data and test results are showed on a 320*240 LCD. All the test results could be printed by the micro printer or saved on the storage of the tester. The tester has a good performance on auto protection and anti-disturb.

Main application

• GDBC-901 Three Phase Transformer Turns Ratio TTR Tester is designed according IEC76-1 and IEC60044. 
• 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.
