The non-linear behaviour of silicon carbide varistors can be used to prevent high voltages from damaging protection systems, used in electricity T&D networks. Such ''overvoltages'' may be created when high current transients are incident on high impedances within the protection systems. These may be due to the type of protection system used or created when current transformers are left in open
