How does the over voltage surge affect the power system?
1 Like
Overvoltage surges in a power system can have serious consequences, including immediate & long-term damage to electrical equipment & system stability. These surges are frequently triggered by lightning strikes, switching activities, insulation breakdown, or rapid load shifts.
Overvoltage stresses the insulation of transformers, motors, and other electrical components, which can result in insulation breakdown, short circuits, or flashovers.
Prolonged exposure to high voltage can deteriorate insulation material, shortening the life of equipment and increasing the chance of failure.
Voltage spikes can cause sensitive components like as protection relays, meters, & control circuits to malfunction or be damaged, resulting in inappropriate protective scheme operation and outages or cascading failures.
Furthermore, overvoltage surges can generate large voltage imbalances, resulting in overheating in rotating machines such as motors and generators, lowering their efficiency & reliability. In severe circumstances, these surges can cause widespread blackouts (or) equipment failures, resulting in costly repairs and prolonged downtime.
