Product Introduction:

     Frequency conversion series resonance test equipment adopts 16-bit fine frequency and voltage regulation software, 10KHz carrier frequency, SPWM technology, and imported original IPM integrated modules and other components. It consists of a variable frequency voltage regulating power supply, excitation transformer, high-voltage reactor, high-precision capacitive voltage divider, and compensation capacitor.

    With the widespread application of cross-linked ethylene cables, the length and capacity are continuously increasing. Due to the large test capacity of such cables, traditional test equipment cannot meet the requirements of handover tests and preventive tests. Frequency conversion series resonance test equipment can well meet the test requirements of cable handover tests and preventive tests with a smaller test capacity.
