Abstract
A method and apparatus generates an enhanced trip time curve capable of capturing both the non-sinusoidal energy and series effects. Relevant data including time, current, and energy is plotted on a three-dimensional set of axes. The resultant three-dimensional representation is useful for representing trip times for a protection device accounting for energy effects, and for determining selectivity in a multi-tier electrical distribution system.
