Dead tank circuit breaker surge arrester

A method for limiting transient over-voltages occurring across a respective first high voltage terminal or second high voltage terminal of a circuit breaker comprising:

• providing a middle tank portion;
• providing a first portion coupled to a first side of the middle tank portion, and a second portion coupled to a second side of the middle tank portion;
• providing a first high voltage terminal coupled to the first portion, and a second high voltage terminal coupled to the second portion;
• providing a post insulator supported and extending from the middle tank portion;
• and
• providing a first surge arrester connecting the first high voltage terminal to a first connector extending from the post insulator, and a second surge arrester connecting the second high voltage terminal to a second connector extending from the post insulator;
• wherein either the first surge arrester or the second surge arrestor limit transient over-voltages occurring across the respective first high voltage terminal or second high voltage terminal when the circuit breaker is open.
