The workshop commences by defining power quality and exploring different indicators and common issues related to power quality. Each of these problems is thoroughly examined, analyzing the underlying causes and proposing corrective measures to address them. Special attention is given to the problem of surges, as supply surges can result in significant damage to power systems and sensitive equipment. The principles of surge protection are extensively discussed to mitigate the risks associated with surges.
