“…At present, the traditional PD sensors are saturated, tremendous, bulky, low sensitivity, and high cost compared to Rogowski coils (RC), such as High-Frequency Current Transformer (HFCT) and Coupling Capacitor (CC) [22]. The PD behavior will be measured by the current pulse when the RC is clamped around the supply cable [6,23].…”

This paper presents the modelling of the online partial discharge (PD) measurement of the medium voltage (MV) power cable. Recently, PD monitoring trends are rapidly increasing due to high demand on reliable systems. Degradation are mainly due to the presence of PD in the high voltage power equipment used. PD measurement is therefore a highly recommended task to early detection of the degradation insulation for high voltage (HV) equipment in order to avoid breakdowns. Real network modelling is necessary to improvise system design in order to find the efficiency in a real power system network. In this paper, modelling focuses on a real distribution network by applying Rogowski coil (RC) as a detection sensor to trigger PD activity. The simulation is performed to determine the functionality and reliability of the system with the RC application in the network. The analysis is performed in the ATP-EMTP and MATLAB Simulink software environments. In addition, this paper contributed to justify the approach of a simplified PD sensor and measurement system. This PD measurement system provides a complete solution in the context of condition-oriented monitoring for the ability to apply the RC to trigger PD activity in the power distribution network.

“…This paper presents the wavelet based de-noising for on-site partial discharge measurement signal, where PD signals are recorded by using Rogowski Coil (RC) and then MATLAB coding are used to de-noise measured PD signal. In general, electrical partial discharge diagnostics uses pulse and high frequency current induced by PD in an electrical PD measurement circuit [20,21]. RC is a sensor which can detect a PD signal based on the magnetic field intensity of the measured signal [22].…”

<span>This paper presents, wavelet based de-noising technique for on-site partial discharge (PD) measurement signal. The signal is measured from medium voltage power cable at 11 kV distribution substation. The best mother wavelet, decomposition level and the type of threshold for the de-noising technique are selected based on the signal to noise ratio (SNR) aggregation. The SNR aggregation is determined based on the minimum, maximum, mean and standard deviation parameters. The same standard de-noising procedure is applied for two different PD signals and the selection parameters are done based on the accuracy of de-noising analysis. The analysis is performed in MATLAB software environment and Daubechies 2 (db2) is found as the best mother wavelet at tenth decomposition levels with soft threshold type. This study is specifically performed to develop the de-noising procedure for on-site PD measurement. Overall results indicate that the right selection of the de-noising procedure will help to improve the PD signal detection from on–site measurement.</span>

“…PD is electrical discharge that partially bridges the isolation between conductors, as result of electrical stress in or on the surface of insulation [6], [7]. PD occurs when locations voltage breakdown is smaller than localized electric field, with presence of void, crack, foreign material, or structural changes.…”

In this study, a review on categorization of partial discharge (PD) detection technique is presented. The PD detection is important in order to monitor and diagnosis the insulation health on high voltage (HV) power component. PD at high voltage transformer occurs due to the unscheduled maintenance, aging of equipment, breakdown of insulation, gas bubbles in insulation liquid, manufacturing error and etc. In order to maintain constant and high as possible of the transformer performance, it is essential to control, detect and measure the PD phenomena. There are many methods have been developed based on point of observation; optical, chemical, acoustic and electrical. However, the different methods have their own advantages and disadvantages.
