Product Description
Application
Transformer Load and no-load loss characteristics tester ,Portable capacity and no-load tester is a high-precision instrument for measuring transformer capacity, no-load, load and other characteristic parameters. This instrument is a multi-function measuring instrument, which is equivalent to the usual two kinds of test instruments: transformer capacity tester + transformer characteristic parameter tester. It can accurately measure a series of power frequency parameters such as capacity, type, no-load current, no-load loss, short-circuit (load) loss, impedance voltage and so on of various transformers.
Features
1.It can accurately measure the capacity of various distribution transformers, which is convenient and accurate.
2.It can measure the no-load current, no-load loss, short-circuit voltage and short-circuit (load) loss of the transformer.
3.The instrument automatically performs range switching, allowing the measurement of a wide range of voltage and current, and simple wiring.
4.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.
5. A single machine can complete the measurement of the load test of the distribution transformer under the full current of 1000KVA; under one third of the rated current, it can complete the measurement of the load test of the distribution transformer under 3150KVA (under one third of the rated current) , the instrument can be converted to the load loss parameter under the rated current).
6. All test results are automatically corrected. The instrument can automatically perform various corrections such as waveform correction, temperature correction, non-rated voltage correction, non-rated current correction, etc., making the test results more accurate.
7. Large color touch screen, high-brightness LCD display, full English character menu and operation prompts to achieve friendly man-machine dialogue, touch buttons to make operation easier, wide-temperature LCD with brightness adjustment, suitable for winter and summer seasons.
8.The instrument can preset 40 groups of test parameters by the user, and these parameters can be deleted and added at any time as needed, which is very convenient to use.
9.With its own real-time electronic clock, it can automatically record the date and time of the test, which is conducive to the preservation and management of the test results.
10.Panel-type thermal printer, which can quickly print test results on site.
11.Data (test product settings, measurement results, test time, etc.) have power-down storage and browsing functions, can store 500 sets of experimental results, and can transmit data online with a computer.
12.Allows external voltage transformers and current transformers to perform extended range measurement, and can measure the test object of any parameter.
