1. Overview

This instrument is a multi-functional measuring instrument, which is equivalent to two usual test instruments: transformer capacity tester + transformer characteristic parameter tester. It can accurately measure a series of power frequency parameters such as capacity, energy efficiency grade, type, no-load current, no-load loss, short-circuit (load) loss, impedance voltage and so on.

This product has many advantages such as small size, light weight, high measurement accuracy, good stability and simple operation. It can completely replace the previous method of measuring transformer loss and capacity by multi-meter method, the wiring is simpler, the test and recording are more convenient, and your work efficiency has been greatly improved.

2. Functional characteristics

It can accurately measure the capacity of various distribution transformers, which is convenient and accurate.

It can measure the capacity, energy efficiency class, no-load current, no-load loss, short-circuit voltage, short-circuit (load) loss of the transformer.

The range is automatically switched inside the instrument, which allows a wide range of measured voltages and currents, and simple wiring.

When doing the no-load and load test of the three-phase transformer, the instrument can automatically judge whether the wiring is correct and display the vector diagram of the three-phase voltage and current.

The single machine can complete the measurement of the load experiment under the full current of the distribution transformer below 1000KVA; The load test measurement of the distribution transformer below 3150KVA can be completed at one-third of the rated current (at one-third of the rated current, the instrument can be converted to the load loss parameter under the rated current).

All test results are automatically corrected. The instrument can automatically perform a variety of corrections such as: waveform correction, temperature correction, non-rated voltage correction, non-rated current correction, etc., so that the test results are more accurate.

320x240 large screen, high-brightness LCD display, full Chinese character menu and operation tips to achieve friendly man-machine dialogue, touch buttons to make operation easier, wide temperature LCD with brightness adjustment, can adapt to winter and summer seasons.

The instrument can be preset by the user 40 sets of test parameters, and these parameters can be deleted and added at any time as needed, which is very convenient to use.

It comes with a real-time electronic clock, which automatically records the date and time of the experiment, which is conducive to the preservation and management of the experimental results.

Panel-mounted thermal printer for quick printing of test results on site.

The data (sample settings, measurement results, test time, etc.) has the function of power-off storage and browsing, which can store 500 sets of experimental results and transmit data online with the computer.

Allows external voltage transformers and current transformers to be extended range measurements, and can measure test samples of any parameters.
