Overview

The TLHG-503CT volt ampere ratio polarity comprehensive tester is a multifunctional on-site testing instrument designed specifically for testing the volt ampere characteristics, ratio, polarity, error curve, calculation of inflection points, and secondary side circuit inspection of current transformers. During the experiment, only the test voltage/current value needs to be set, and the equipment can automatically boost/boost the current, and quickly display the voltage current characteristic curve or transformation ratio, polarity, and other experimental results of the transformer. It supports data saving and on-site printing, which not only saves the tedious labor of manual voltage regulation, manual recording, and curve drawing, but also achieves unlimited storage through a USB flash drive. Test data can be edited through a computer

Product Details

TLHG-503CT Voltage Current Ratio Polarity Comprehensive Tester

Main features:
1、 Safe and reliable:
Domestic MBC power control technology, single-phase AC220V input power supply, and the working power supply shares the same input port with the power supply, making the design more scientific and reasonable, and the use safer and more reliable.
2、 Complies with national maintenance regulations:
The power output of the device is all true voltage and current values, and the waveform is a standard sine wave with a frequency of 50-60Hz; Can truly and effectively simulate the true state of the transformer, in compliance with relevant national maintenance regulations.
3、 Large output capacity:
When single machine 220V input is usedz·uiHigh voltage output 0-1000V, single machinez·uiHigh current output 0-600A, very suitable for on-site maintenance and use.
4、 Fully functional:
It can detect the volt ampere characteristics, transformation ratio, polarity, 5% and 10% error curves, CT primary current and CT demagnetization, etc. of CT, making it easy to achieve multi-purpose use of one machine.
5、 Simple wiring method:
Adopting a single power input port; Only 6 test ports can complete all CT testing projects, with a safe and simple wiring method that is very suitable for on-site use. It can effectively reduce labor intensity and improve work efficiency;
6、 Large testing scope:
For CT variable ratio measurement ranges of 15000A/5A and 3000A/1A.
Note: Measurement range without the need for an external booster or an external current booster
7、 Quick printing:
Using a thermal printer to automatically screen and print typical report usage data, it is very suitable for on-site data comparison.
8、 Large capacity FLASH storage: can store 1000 sets of test data without loss after power failure.
9、 USB interface: convenient for connecting modern laptops.
10、 Small size and light weight: convenient for on-site use.
