Cable Positive Sequence Impedance Measurements What Are The Requirements In The Process Of

Cable conductors of AC resistance and cable resistance of three phase shared the Phasor and referred to as positive sequence impedance.

Cable line of are sequence impedance General can in cable disc Shang directly measurement, measurement Shi General using lower of voltage, so, need with buck transformer for buck, Buck device used star shaped wiring, capacity General for 10kVA above, has more wide of voltage regulation range, measurement Shi Exchange power should compared stable, to guarantee measurement Shi current reached provides of requirements, actual voltage table of read numerical must is cable end of voltage, test current best close cable long-term allows contains flow, measuring read the table meter of numerical Shi, Current read on three tables of values.
