The falling trees on covered-conductor (CC) overhead distribution lines produce partial discharges (PDs). The measurements have been taken in the laboratory and PD signal characteristics under various circumstances have been described. In this paper, an on-line single-phase PD monitoring system using Rogowski coil is simulated in EMTP-ATP. The simulation results are compared with those obtained from...
In a Bayesian selectivity technique has been introduced to identify the faulty feeder in compensated medium voltage (MV) networks. The proposed technique has been based on a conditional probabilistic method applied on transient features extracted from the residual currents only using the Discrete Wavelet Transform (DWT). In this paper, the performance of this selectivity technique is evaluated when...
In this paper, ATP-EMTP simulation environment is used to compare the performance of on-line three-phase partial discharge (PD) monitoring system for overhead covered-conductor (CC) distribution lines. The PD measuring system has been developed using two different types of CC line models, i.e. Clarke's and JMarti models. Rogowski coil is used as the sensor to detect and localize PDs caused by falling...
