Experimental Validation of Multiconductor Cell Analysis by Overhead Line Field Measurements

Multiconductor Cell Analysis (MCA) is a matrix algorithm computing the electrical steady-state regime of any asymmetrical multiconductor system. This paper presents an experimental validation of MCA, which is carried out by a measurement campaign performed on the Extra High Voltage (EHV) Dolo-Venezia Nord 18 km long double-circuit OverHead Line (OHL). By considering the double-circuit configuration of this line, it has been assessed the impact of one inducing circuit, kept in service, on the other circuit, kept out of service, for the evaluation of induced voltages and currents. One more time, comparisons between computations and measurements confirm the good agreement between MCA and the physical behavior of multiconductor systems.
