ABSTRACT:
The utilization of clusters of two or more metal oxide varistors (MOVs) connected in parallel for suppressing surges and transients. Particular embodiments are disclosed for both grounded and ungrounded power systems. Also disclosed are two-stage and multi-stage uni-directional and bi-directional suppressors. Uni-directional means that the suppressor is intended to be placed between a source and a load for the purpose-of preventing voltage surges and transients from being propagated from the source into the load. Bi-directional suppressors are intended to be placed between a source and a load and provide suppression in both directions simultaneously.
