Power quality problems encompass a wide range of different phenomena. Each of these phenomena may have a variety of different causes and different solutions that can be used to improve upon the power quality and equipment performance. This paper analyses the malfunctioning of a capacitor bank at a quarry processing company (QPC) in the Western Region of Ghana. The QPC had held the Electricity Company of Ghana (ECG) responsible for the damage. According to QPC, the damage was due to frequent power fluctuations and outages experienced from the ECG distribution network. The paper presents and discusses techniques used to investigate the cause of the problem. The result of the analysis of the damage was conducted using the electromagnetic transient programme (EMTP) and relates the damage to harmonic resonance produced from the QPC power distribution network. It is recommended that, for reliable, safe and economic operation of capacitor banks, the harmonic content of an electrical installation is measured and analyzed before installation.

-Industrial power distribution system includes many kinds of non-linear loads, which produce the harmonics during energy conversion transition. The single-tuned passive filter is widely used to absorb the harmonics and attenuate its undesirable effect in the distribution system. However, the passive filter might be severely stressed, and sometimes even damaged, due to the absorption of harmonics. There is voltage rise on the capacitor when the single-turned harmonic filter is applied. When the capacitor voltage rose above the allowable limit, the expected life of the capacitor will considerably deteriorate. On the other hand, the reactor can experience the spike voltage even if the voltage and current of the capacitor are within the allowable limit, and this accumulated voltage stress of the reactor causes its premature fault. In this paper, we analyzed and compared the harmonic voltage and current of the reactor and capacitor in a single-tuned harmonic filter through the EMTP software and verified them with the experimental results.
