  • Methods and apparatus for analyzing high voltage circuit breakers
    Patent number: 6965238
    Abstract: Methods, computer program segment and apparatus for analyzing high voltage circuit breakers are provided. The method includes determining a circuit breaker contact closing time, determining a circuit breaker contact opening time, and determining a circuit breaker pre-insertion resistor resistance value using at least three voltage samples and three current samples to facilitate reducing an induced current measurement error. The computer program segment is embodied on a computer readable media and is programmed to determine a circuit breaker contact closing time, determine a circuit breaker contact opening time, and determine a circuit breaker pre-insertion resistor resistance value using at least three voltage samples and three current samples that facilitate minimizing an induced current measurement error.
    Type: Grant
