Duty cycle of circuit breaker

WebDuty cycle is well defined as D C = T h i g h T p e r i o d Here T h i g h is the time your signal is high out of the total period of length T p e r i o d . In percents it will be D C % = 100 T h i g h T p e r i o d So D C % = 0 implies T h i g h = 0, i.e. the signal is always low.
