UHV 320 transformer short circuit tester

Product Overview

Description

Brief Introduction

This equipment according the JB/T501-91 : power transformer test regulation and GB1094-96: power transformer , can test voltage, average voltage, power, frequency, and others parameters for the single and three phase transformer, accuracy is 0.1.With intelligent and professional designs, it applies to no-load, load, inductance tests for transformer. It is the ideal renewal equipment for traditional pointer type devices.

Products features

1.Can test the transformer on load current, no load losses, short circuit voltage, short circuit (load) losses
2. Can make harmonic test, can analyze 31 harmonic.

3. the device auto-switch the measurement range, wide range for voltage, current test, easy to connect wire.

4.the device can auto check if the wire was correctly connected, and display the vector diagram of three phase current, voltage when test the three phase transformer.

5.single machine can make the loading test for substation transformer under 1000KVA; can make the loading test with 1/3 of the rated current for substation transformer under 3150KVA (the device can convert to the loading losses parameters if the rated current under 1/3 of the rated current)

6.all test results can be auto calibrated. It can calibrate following: wave form, temperature, non-rated voltage, non-rated current, so improve the accuracy.
7. 320x240 LCD, friendly man-machine interface, brilliance control, adapts to all seasons. 8. The device can preset 40 groups parameters ,and these parameters can be added or deleted according users needs.

9. With electronic clock, auto record the data, time , it is good for saving and managing the test results.

10. panel type printer can print the test results on site.

11. data (specimen setting, test results, measurement time) can be saved on power failure and can be reviewed, it can store 500 groups test results, can connect with computers to transmit data.
12.allow external connecting CT and PT to make extension measurement, can test the specimen with any parameters.
