It often faces unforeseen overvoltages in the system. But what does overvoltage mean? Overvoltage is associated with the electric field strength, namely with its increase. Overvoltage happens when the electric field strength reaches a value that is dangerous for the insulation state. What consequences might overvoltage cause? Factories are losing tens of millions per year due to power interruptions. Moreover, the cost of replacing equipments damaged because of voltage spikes is very high. Power industry experiences huge losses of production. The effect of transient overvoltage on substation equipment and the conforming protection against it are likely to be the most important elements of this problem. popup.nrat_date 2025-05-12 Close
