Some Fundamental Aspects or Recovery Voltages

Whether any load-interrupter switch successfully, interrrrupts when called upon to do so depends solely upon how the recovery voltage builds up across the switch as a function of time in comparison with the switch contacts. This paper deals with recovery voltages in a graphical manner, so that a visual concept of recovery voltage versus time across a switch is provided in resistive loads, inductive loads, and capacitive loads. As a special case, the recovery voltage across a switch in a loop-sectionalizing application is also treated in this paper.
