used in transmission lines at energy systems and prevent rising the voltage level of line |
Surge arresters are the devices that used in transmission lines at energy systems and prevent rising the voltage level of line with their short circuit property in the cases of excessive voltage waving Surge arresters are sensible to voltage and activate with voltage rising changes at current levels on lines do not cause its activity.
