Surge Arresters are an essential component for increasing the reliability of the electricity network as they serve as the primary protection against overvoltage's, whether they're atmospheric and or caused by switching. MV Technology Solutions are the exclusive partner for Siemens Energy Arresters Portfolio for all MV and HV Surge Arresters in the Australian Market.
When selecting a Surge Arrester, there are several options and considerations, but the basic requirements of a Surge Arrester still remain the same;
The Surge Arrester should provide adequate protection with a sufficient safety margin, which means that overvoltage's at the device to be protected must always remain below its withstand voltage
The Surge Arrester should be dimensioned for stable continuous operation, which means that the arrester must remain electrically and thermally stable under all conditions while handling all long-term, temporary, and transient stress resulting from network operation.
It is important to remember that these two requirements cannot be fulfilled independently. A reduction of the protective level automatically means a higher degree of specific electrical stress during continuous operation, and equally, the continuous operating voltage of an arrester cannot be increased arbitrarily without raising its protective level as well.
