What causes a re-strike in a lightning arrester?
Surge voltages associated with the discharge of lightning arresters at other locations within the facility. When capacitors are switched in and out of the circuit, it is possible to get a re-strike when interrupting the capacitor circuit current. A steep-front voltage excursion may be created from each re-strike.
Can a surge arrester protect a capacitor?
Generally speaking, capacitor protection by surge arresters has been a difficult task before Z n O arresters became available. The high discharge currents and possible energies associated with an arrester operation at a capacitor bank heavily stressed the spark gaps in a S i C gapped arrester.
Do capacitor banks need surge arresters?
Many capacitor banks are operated without surge arresters. However, there are a variety of reasons to instal arresters: To prevent capacitor failures at a breaker restrike or failure. To limit the risk of repeated breaker restrikes. To prolong the service life of the capacitors by limiting high overvoltages.
What are the dimensioning parameters of a lightning arrester?
For higher system voltages, the dimensioning parameters of the arrester tend to be lightning impulse withstand of partial arcing distances and switching impulse withstand of the complete arcing distance. As discussed herein, an arrester must have sufficient insulation withstand across its own housing.
How do lightning arresters work?
Lightning arresters are coordinated with standard electrical equipment insulation levels so that they will protect the insulation against lightning over voltages. This coordination is obtained by having an arrester that will discharge at a lower voltage level than the voltage required to break down the electrical equipment insulation.
Do switching surges affect arrester design?
Due to the nonlinear relationship between withstand voltage and arcing distance, switching surges will influence the arrester design more on system voltages above 362 kV than lightning impulse withstand and the specifics of the design can play a role as well.
