Product Description

Class 0.2 Transformer Load and No-Load Tester

Introduction:

Class 0.2 Transformer Load and No-Load Tester can measure the voltage, short circuit current, no-load loss, and short circuit (load) loss of a transformer. It is possible to conduct harmonic tests and analyze the 31 harmonics. The instrument shifts ranges automatically, enabling voltage measurement, a large current range, and straightforward wiring. Test the three-phase transformer under load and at no load to see if the wiring is proper. The instrument will also show the three-phase voltage and current vector.

One tester is all that is required to measure the load experiment under a 1600 kVA distribution transformer at full current; however, under 2500 kVA distribution transformers, the measurement can be completed in 1/3 of the rated current (in this case, the instrument can be used to calculate the load loss parameters under the rated current). Automatic corrections are made to all test results. Automatic corrections are made to all test results. The instrument has a wide range of correction capabilities, including waveform correction, temperature correction, non-rated voltage correction, non-rated current correction, and others.

Feature:

♦ It can assess the transformer's short circuit voltage, short circuit (load) loss, no-load current, and no-load loss;

♦ It is possible to conduct a harmonic test and analyze the 31 harmonic;

♦ The instrument shifts the range automatically, enabling voltage measurement, broad current range, and straightforward wiring;

♦ Perform a three-phase transformer no-load, load test; the instrument will show the three-phase voltage and current vector and will automatically decide whether the wiring is proper;

♦ Under 1000 KVA distribution transformers, the load experiment can be measured at full current; under 3150 KVA distribution transformers, it can be measured at 1/3 of the rated current (the instrument can be converted to the load loss parameters at the rated current);

♦ Automatic corrections are made to all test results. The device has a wide range of correction capabilities, including waveform correction, temperature correction, non-rated voltage correction, non-rated current correction, and more;

♦ LCD with a big screen of 320 * 240 pixels, high brightness display, comprehensive menu, and quick operation in English characters to actualize man-machine conversation; touch button for easier operation; LCD with a broad temperature range and brightness adjustment;
