Abstract
In an arrester comprising a characteristic element made up of a stack of a plurality of metal oxide resistors, parallelly connected capacitor and a linear resistor are connected between the characteristic element and ground, and voltage drop across the linear resistor is used to light a neon lamp or to operate an alarm device for detecting deterioration of the characteristic element. To protect the capacitor and the linear resistor at the time when the arrester operates, a nonlinear resistor may be connected in parallel with the capacitor and the linear resistor.
