JYR Power Transformer Capacity Tester

Overview

JYR Power Transformer Capacity TesterSpecially designed for high-precision measurement of transformer capacity parameters and transformer loss parameters, this high-precision tester is developed and researched according to the power industry standard DL/T911-2004 for measuring transformer capacity and loss parameters. It can work with an external power supply and internally synthesizes three-phase standard sine wave signals (not simply inverter AC output, ensuring the accuracy of test data for various test items under non rated conditions). Through a power amplifier, it can provide a three-phase precision AC test source; When measuring the capacity and short-circuit loss of transformers, there is no need for external three-phase testing power supply, voltage regulator, current boosting and other auxiliary equipment, simplifying wiring and greatly improving work efficiency and test results.

This instrument is a combined power detection equipment, mainly consisting of an active transformer capacity tester and a transformer loss parameter tester. It can accurately measure a series of power frequency parameters such as capacity, no-load current, no-load loss, short-circuit loss, impedance voltage, etc. of various transformers. Its main features include small size, light weight, high measurement accuracy, good stability, and easy to learn operation. It completely replaces the traditional method of measuring transformer loss and capacity using multiple meters, with simple wiring, convenient testing and recording, greatly improving work efficiency.

Product features

It can measure the capacity of various distribution transformers and electrical transformers on site, and the transformer model discrimination includes national standard parameters such as S7, S9, S11, S13, S15, etc. No need for additional power supply, detection is more convenient and faster

The applied high current short-circuit wire is very convenient for on-site short circuiting of low-voltage terminals or aluminum bars, and the operation is * * and simple

Combined with external power supply and equipment for voltage regulation, voltage boosting, and current boosting, various transformer characteristic data such as no-load current, no-load loss, impedance voltage, and load loss can be measured

All test results have been automatically calibrated. You only need to input relevant parameters (such as temperature, no-load correction factor, etc.), and the instrument will automatically perform various corrections such as waveform distortion correction, temperature correction, non rated voltage correction, non rated current correction, etc., making the test results more accurate

In the measurement of transformer characteristics, the voltage * large range can reach 750V, the current * large range can reach 100A, and there is an internal protection circuit. When measuring, there is no need to switch gears to ensure measurement accuracy, and there is no need to worry about burning out the instrument due to incorrect gear selection

When testing the characteristics of transformers, the voltage and current ranges can be flexibly and easily expanded by simply connecting external voltage transformers and current transformers, greatly expanding the testing range of the instrument

Adopting a 5.7-inch large screen, high brightness color LCD display, full Chinese menu and operation prompts, a very friendly human-machine dialogue interface has been achieved; Wide temperature and adjustable brightness LCD screen, adaptable to different environmental temperatures

Adopting standard USB communication interface (many outdated manufacturers still use 232 serial port for their products), it facilitates data uploading and analysis with computers

Based on the test results of no-load and load losses, the performance level of three-phase oil immersed distribution transformers and electrical transformers can be automatically estimated for on-site reference by staff
