Effects of Rogowski Coil and Covered-conductor Parameters on the Performance of Pd Measurements in Overhead Distribution Networks
نویسندگان
چکیده
An on-line single-phase partial discharge (PD) measuring system using Rogowski coil is simulated in EMTP/ATP for the monitoring of falling trees on coveredconductor (CC) overhead distribution lines. The simulation results are compared with those obtained from the laboratory measurements. The effect of Rogowski coil terminating impedance is analysed for the performance of PD measuring system. The proposed model can be used to estimate the length of the practical CC lines at which PDs due to falling trees can be detected; thus, deciding the number and positioning of the sensors over a particular length of the CC lines.
