A number of studies have shown that better DG PV integration impacts, on the network are obtained when the DG PV are operated at lower power factors. However, at lower power factors, losses tend to increase, whilst voltage improvement is rather realized in the sub — transmission network. In this study, with the help of the CYME distribution software, the optimal impacts of varying the DG PV power...
Within a period of two years, the Electricity Company of Ghana (ECG) lost a total of six grounding transformers in a particular substation. The situation created a lot of instability and resulted in huge productivity losses to both the company and its customers. The failures were believed to be related to wrong selection of grounding transformer rating. However, using the concept of capacitive charging...
