Product Description

Transformer Characteristic Comprehensive Tester

DARUI Electric recommends

Product Introduction

The Transformer Characteristic Comprehensive Tester is designed for testing transformer volt-ampere characteristics, ratio testing, and polarity discrimination. It is a multifunctional test instrument. This instrument uses high-efficiency, low-consumption quality materials and a specially wound booster, with a microcontroller microprocessor for data acquisition, analysis, and storage. It has a built-in micro printer that can print test data and curves. When measuring CT ratio, it can automatically calculate the ratio value. One person can complete all testing work. This transformer comprehensive characteristic tester has the characteristics of light weight and easy operation.

Functional Features

1. This transformer characteristic comprehensive tester has comprehensive functions, can test CT/PT volt-ampere characteristics, ratio and polarity, 10% error curve, angle difference, and ratio difference.

2. Only need to set the test voltage, current, and step size. The device will automatically boost and automatically plot the volt-ampere characteristic test curve, saving the tedious work of manual voltage regulation, manual recording, and curve plotting. Fast, simple, and convenient.

3. Can connect an external booster to expand the output voltage range.

4. For volt-ampere characteristic test, the single machine output voltage is 0-2500V, current 0-20A; with external booster, output voltage 0-4000V, current 0-1.5A, can do 500kV class 1A transformer volt-ampere characteristic test.

5. 220V single power input, avoiding the danger of using 380V.

6. Large screen LCD display, directly shows the volt-ampere curve during testing, intuitive and convenient. Built-in micro printer for convenient printing of test data.

7. Uses digital keyboard for convenient number input.

8. With large capacity memory, can store 100 sets of test data, data will not be lost when power is off.

9. RS232 communication interface, can connect to a computer for testing, and test data can also be uploaded to the computer for editing and saving.
