Transformer short-circuit impedance test system main functions and features:
1. Short circuit impedance measurement:
The low-voltage short-circuit impedance test for transformers can display three-phase or single-phase display voltage, current, active power, impedance, impedance voltage percentage, reactance, and leakage inductance in the same screen.
2. Measurement of no-load loss:
The instrument shows three-phase voltage, three-phase current, and three-phase power. The instrument displays the distortion rate of the applied power waveform and calculates the transformer's no-load current percentage and no-load loss.
3 transformer short-circuit impedance test system load loss measurement:
Display three-phase voltage, three-phase current, three-phase power, automatically calculate the transformer impedance voltage percentage, converted to the rated temperature, rated current load loss, the instrument has a frequency conversion function, can accurately measure in a wide frequency range .
4. Phase measurement:
Used to check for defects in single-phase windings of three-phase transformers or where no three-phase power is available on site. The phase separation test uses a single-phase power supply. After measuring each single-phase data, it can be automatically converted into three-phase parameters.
Exceeding the measurement range of this instrument, it can increase the function of an external voltage or current transformer according to customer needs. This requires special instructions from the customer when ordering.
5. Transformer short-circuit impedance test system zero-sequence impedance measurement:
Zero-sequence impedance measurement is applicable to transformers with high-voltage side star point neutral point. The instrument can record zero-sequence impedance, zero-sequence reactance, zero-sequence inductance, impedance angle and zero-sequence resistance.
6. Large-screen liquid crystal display of the instrument can display three-phase voltage, three-phase current, three-phase power, three-phase impedance value, three-phase impedance voltage percentage, three-phase reactance value, three-phase leakage inductance value, and three-phase average on the same screen. Voltage, average current, total three-phase power, and related data. The instrument uses a Chinese menu, Chinese tips, and simple operation.
7. The transformer short-circuit impedance test system is equipped with a U-disk interface, which can import the data stored in the instrument at any time into the U disk. When the instrument is tested, it can be directly stored in the U disk.
8. Built-in memory, no loss of power, the instrument can store 200 sets of data.
9. The system comes with a printer that can print test data and print memory browsing data.
10. The transformer short-circuit impedance test system has a permanent calendar and clock function for time calibration.
