Abstract

This contribution quantifies the accumulated arcing stress inside high-voltage circuit breakers during a 25 year period of operation. Ageing mechanisms due to this arcing stress are discussed briefly. The aim is to design a suitable test program to verify endurance against this accumulated arcing stress: electrical endurance. Passing this test program should assure a period of 25 years without major maintenance. Data of fault- and network characteristics collected worldwide are used in a statistical computer model in order to quantify a realistic electrical endurance test program in a recently (2008) revised IEC standard. The actual standardisation status is outlined and discussed, and includes the situation for medium voltage breakers
