WebApr 1, 2006 · The duty cycle imposed on switchgear batteries usually consists of momentary high ampere loading during charging of the respective tripping or closing springs, in addition to the small continuous load of powering protective relays and lights. 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.
