Investigation and Mitigation of Temporary Overvoltage Caused by De-Energization on an Offshore Wind Farm

open access: yesEnergies, 2020
The Ferranti effect could cause a rise in voltage along the cables on a wind farm if the circuit breakers at the receiving ends are switched off. Ferroresonance could also occur due to stuck pole(s) of the circuit breaker during de-energization.

Temporary overvoltage duty of surge arresters in noneffectively grounded systems

open access: yesElectrical Engineering in Japan, 1997
Important characteristics of metal oxide surge arresters depend on the specified temporary overvoltage duty requirement due to the volt–ampere characteristics. However, there are few reports on the duty of surge arresters in noneffectively grounded systems.

Development Of Algorithms For Measuring Nonsinusoidality Voltage And Temporary Overvoltage [PDF]

open access: yes, 2021
Today, operating electrical networks, low and high voltage devices, and engines cause incidents that are characterized by the deviation of parameters from the nominal values. Yet, due to switching of the load cause temporary overvoltages. Besides, emergency modes caused by power outages and sudden failure of equipment of consumers, additionally cause ...
