Voltage surge is one is the most common power quality problems most facility faces. Voltage surge is a surge in voltage or power in an electrical circuit. A voltage surge can either be generated internally inside a facility during switching of devices or came from external source due to lightning and utility grid switching. According to IEEE Standards, the standard protection is to have Surge Protection Device (SPD) or Transient Voltage Surge Suppressor (TVSS) installed according to different categories for complete protection.
