Overvoltage protection of capacitor banks
2011 International Symposium on Lightning Protection, 2011The application and effectiveness of MO surge arresters to capacitor banks is discussed. Principle application rules for different configurations are given. The influence of MO arresters with different ratings on voltage and current at the capacitors and at a re-striking circuit breaker respectively is shown and quantified.

THE ASDEX OVERVOLTAGE PROTECTION SYSTEM
1981The ASDEX overvoltage protection system completes the favourable properties of the ASDEX coils and rectifiers. It uses properly matched standard elements and meets the requirements for operational and fault conditions in a very economic and reliable way.

Thyristors with overvoltage self-protection
1981 International Electron Devices Meeting, 1981Power thyristors which are immune to destructive triggering by overvoltage transients have been designed, fabricated, and tested. A 10- mil deep well was etched in the gate region prior to the final p-type diffusion. This modified the forward blocking junction so that it avalanched at 2800V.

Protection of Section Parts from Overvoltage
2021 IEEE 2nd KhPI Week on Advanced Technology (KhPIWeek), 2021World practice of operating electric networks shows that reclosers are used to partition them, as a rule. National regulatory documents governing the use of reclosers do not yet exist, which raises questions related to their operation. One such issue is surge protection for the recloser.

The increased occurrence of temporary overvoltages caused by commingling in over-built systems is a growing concern to electric utilities and end-users. These events are usually caused by transmission or sub-transmission lines dropping and contacting distribution lines during storms and traffic accidents that damage power poles.

Power distribution system equipment overvoltage protection
IEEE Transactions on Industry Applications, 1994Application of surge overvoltage protection devices in general is based upon rule of thumb without the benefit of understanding basic parameters, system components and configuration, and energy content of the surge. This may result in the selection of an inadequate device.
