Zero Surge Inc.

Zero Surge was incorporated in March 1989 by J. Rudy Harford, President and Chief Engineer. As an independent consultant who designed and manufactured computer networks, Mr. Harford was given the challenge of reinventing the surge suppressor after a customer lost two television sets to power surges despite an investment in surge protection.,/p>

When Mr. Harford examined the failed surge suppressors, he found that the basis for the protection was metal oxide varistors (MOVs), inexpensive components which failed in normal service, leaving no indication that the television sets were totally unprotected. He began thinking about circuit design alternatives to the unpredictable and failure-prone MOV type.

Using computer-aided circuit design, Mr. Harford developed and patented a series-mode surge suppression circuit which protects against worst-case surges, unlike the suppressors on the market which often fail after minor surges.
