1, can accurately measure the capacity of various distribution transformers, passive measurement, convenient and accurate.
2. The internal power supply automatically generates a three-phase high-power test power supply.
3. It can measure the no-load current, no-load loss, short-circuit voltage and short-circuit loss of various types of transformers.
4, can automatically perform waveform distortion correction, temperature correction (provide simple temperature correction and additional loss are corrected in two ways), voltage correction (no-load test under non-rated voltage), current correction (short circuit under non-rated current conditions The test) is very suitable for units that do not have to perform the short-circuit test condition of a slightly larger transformer.
5, can measure voltage and current harmonic content and total harmonic distortion.
6, can be a simple vector analysis, drawing vector.
7. Display the waveform of each electrical parameter and use it as an oscilloscope.
8, the voltage loop wide limit: the maximum voltage can be measured to 750V, without changing the gear to ensure accuracy. The instrument itself will not be damaged due to the wrong selection of voltage range.
9, capacity measurement range: 20KVA ~ 100000KVA.
10, the percentage of battery power indicator function, not a simple loss alarm.
11, large-screen, high-brightness color LCD display, full-Chinese menu and operating tips to achieve a friendly man-machine dialogue, conductive silicone touch keys to make the operation easier, longer button life.
12. The user can print out the test data through the micro printer at any time.
13. The test result storage function can store 200 sets of capacity test data.
