Product Description

TTR testing equipment Portable Power Transformer Turn Ratio Meter

GDBC-901 TTR testing equipment Portable Power Transformer Turn Ratio Meter could be applied to test the turns ratio and group vector of single or three phase transformer. Also the connection group of transformer could be calculated with the ratio. All parameters are measured in one test for three phase transformer. 
 

Introduction

• 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.

Precautions:

1. Insurance 1 is 2A, insurance 2 is 0.5A. If the test lead is short-circuited, the high and low voltages are  reversed, and the fuse will be blown. After the fuse is blown out, if you take a measurement, it will stop after displaying "Measuring, please wait!". Please shut down, replace the insurance with the same capacity, and retest.
2. Keep good contact during wiring. The instrument should be well grounded.
3. The working place of the instrument should be far away from strong electric field, strong magnetic field and high-frequency equipment. The smaller the power supply interference, the better. The lighting cable should be used. If the power supply interference is still large, the instrument can be powered by the AC purification power supply. The capacity of the AC purification power supply can be greater than 200VA.
4. When the instrument is working, if the LCD display is disordered, all the keys have no response, or the measured value is far from the actual value, please press the reset key, or turn off the power, and then restart the operation.
5. The display has no characters, or the color is very light. Please adjust the brightness potentiometer to a suitable position. The brightness potentiometer is a multi-turn potentiometer with 10 turns.
6. The instrument should be stored in a dry and ventilated place. If it is not used for a long time or the environment is humid, the preheating time should be extended to remove moisture.
7. Used for communication port debugging.
