Digital Transformer Ratio Meter Brief Introduction

Introduction Model HYBC-901 Transformer ratio meter

HYBC-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 functions

v The voltage ratio measurement of three or singe phase transformer

v The group vector measurement of three phase transformer.

v The polarity measurement of single phase transformer or CT/PT

v (CT that knee-point voltage should be more than 80V)

v Voltage ratio error calculation

v Voltage ratio range calculation of three phase transformer

v Current transformer ratio measurement

v Excitation current measurement in ratio testing

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

v Save the test results in the memory internal the tester

v Print the test results by micro printer

v Reverse connection detect unit to prevent the high voltage injected to the operate

v Over current protection in test voltage

v Upload the test results to make word report by RS232 interface
