Lightning Arrester Voltage Protection Level

lightning surge arrester Impact on the power system
Equipment safety protection: Sensitive equipment in the enterprise (such as computers, servers, industrial control systems) is very sensitive to voltage changes. If the surge voltage exceeds the rated tolerance of the equipment, it may cause equipment damage or data loss. Higher surge arrestersUp values ​​will subject the equipment in the power system to higher voltage shocks, increasing the risk of damage.
System stability: If the 11kv lightning arresterUp value is low, the power system will be less impacted by lightning strikes or surges, which is conducive to maintaining the stable operation of the power system, especially for precision equipment. The lower the 15kv lightning arresterUp, the higher the safety.
Select lightning arrester in transformer Recommendations
high voltage lightning arresterUp value selection: 33kv lightning arresterUp value should be selected according to the withstand voltage characteristics of the equipment used by the enterprise. General recommendation: The Up value of electrical equipment should be controlled within 1.2kV to 1.5kV.
For sensitive equipment (such as communications, data center equipment), the Up value should be lower than 1.2kV to ensure that the equipment is not damaged by high voltage during surges.
