in the EPBTC ?
General Information:
EPBTC Transformer Power Analyzer is a new type of tester specially designed and developed for the purpose of sneaking basic electricity charges and private capacity increase for poor power users. It is used for high precision measurement of characteristic parameters such as transformer capacity, no load and load. tester. EPBTC is a multi-function measuring tester, which is equivalent to two kinds of test testers: the 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, and impedance voltage of various transformers.
This product has many advantages such as small size, light weight, high measurement accuracy, good stability and simple operation. It can completely replace the method of measuring transformer loss and capacity by using multi-meter method in the past. The wiring is simpler, the test and recording are more convenient, and your work efficiency has been greatly improved.

Also called: Transformer Iron & Copper Loss Tester, Transformer load/no-load Tester, Transformer Capacitance and Load No Load Tester

Standard: IEC270

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 tester automatically switches the range within the instrument, allowing the measurement voltage and current range to be wide and the wiring to be simple..
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 a vector diagram of the three-phase voltage and current.
5. One can measure the load test below 1000kVA distribution transformer at full current, measuring the load test in 1/3 rated current can be completed under 3150kVA distribution transformers (in the 1/3 of the rated current under the tester can be converted to the load loss parameters under the rated current).
6. All test results are automatically corrected. The tester can carry out many kinds of correction, such as waveform correction, temperature correction, non-rated voltage correction, non-rated current correction and so on.
7. 320 * 240 large screen, high brightness LCD display, touch button makes the operation more convenient, wide temperature LCD with brightness adjustment, can adapt to the winter and summer season.
8. The tester can be preset by the user 40 sets of sample parameters, and these parameters can be deleted at any time as required, and the use is very convenient.
9. With real-time electronic clock, 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, can quickly print the results of the field test.
11. Data (test set, measurement results, test time, etc.) with the power down storage and browsing capabilities, can store 500 sets of test results, and the computer can send data online.
12. Allow external voltage transformer and current transformer to expand the range measurement, can measure any parameters of the subject matter.
