The Field Test of High Voltage Cable Impedance Parameters

Abstract:

The cables in 66 kV and 220 kV systems are used in single-phase style, and it must be grounded between the cables. The connection ways between different lengths of cables are in different ways, thus, it may occur influence to circuit parameters, especially to zero sequence impedance. In order to clarify the situation from theory analysis to calculate impedance under all kinds of connection modes, the paper gives an actual cable measured value, and introduces the correct measuring method, together, points out the matters needing attention in the measurement.
