Transient and voltage surge protection system and method for preventing damage to electrical equipment

A method of preventing damage to electrical equipment due to voltage surges and voltage transients comprising:

• providing a first metal oxide varistor upstream of a transformer, said metal oxide varistor being connected in parallel with a primary voltage source and said transformer;
• providing a second metal oxide varistor downstream of said transformer, said second metal oxide varistor being connected in parallel with a secondary voltage source and said transformer;
• providing a circuit opener downstream of said transformer, said circuit opener being connected in series with said secondary voltage source, said circuit opener being a reset breaker for protecting said transformer from surges greater than the rated value of said second metal oxide varistor by opening to close off current flow;
• and
• utilizing said first metal oxide varistor, second metal oxide varistor and said circuit opener to protect electrical equipment from damage by clamping and breaking voltage surges and transients.
