Abstract : Metal oxide varistors are connected in parallel with grounded capacitors to load outlet terminals coupled to a power source through inductor coils forming a low pass filter with the capacitors to delay propagation of a voltage increasing transient pulse to the power source until ground shunting paths of low resistance are developed in the varistors. Electromagnetic shielding partitions the inductor from the capacitors and varistors within a power outlet box mounting the load outlet terminals to prevent interference with absorption of transient energy by the varistors during the delay in establishing the ground shunting paths.
