Abstrakt: Application of capacitor bank to an electric power system provides well known benefit, including power factor correction, better voltage regulation and freeing up capacity to enable maximum power transfer. However, a major concern arising from the use of capacitors in power system is the possibility of system resonance. In this paper, frequent capacitor bank tripping and failures in two Electricity Company of Ghana (ECG) distribution substations have been investigated. The study was based on EMTP RV simulation. It was found that the failures were related to harmonic resonance. Purposefully selected series connected inductors were recommended to help move the resonant frequencies of the network below characteristics harmonic frequencies. The paper presents and discusses the techniques applied in the investigation and reports the results achieved. [ABSTRACT FROM AUTHOR]
