The accurate measurement method for frequency converters containing a large amount of harmonic, distorted, or non I-frequency electricity is to use instruments with FFT function. For testing high-voltage and high-capacity frequency converters, due to the large values of voltage and current, general instruments cannot meet the requirements. Therefore, voltage or current sensors should be used, and then instruments should be connected for measurement. The WP4000 variable frequency power analyzer can achieve input, output, and efficiency testing of a high-voltage inverter with a voltage of 10kV and a current of 7000A based on different combinations of variable frequency power sensors.

● Including:

● Input values: rated input voltage, rated input current, rated capacity, active power, power factor, input harmonics, input total harmonic distortion.

● Output value: maximum rated output voltage, rated continuous current, rated power, frequency range, overload capacity, output harmonic of each order, and output total harmonic distortion.

Efficiency: The efficiency at various frequencies within the designed frequency range.

The high-power variable frequency speed regulation device is widely used in various industries such as large-scale mining production plants, petrochemical industry, municipal water supply, metallurgical steel, power energy, etc., such as fans, water pump compressors, and steel rolling machines.
