Abstract
Coordination of the overcurrent/time trip characteristics of a hierarchy of overcurrent protection devices is accomplished through a central tester which establishes a pattern of test currents for the individual overcurrent protection devices which simulates a fault at a specified location in the power system. The individual assigned test currents are transmitted over a communications link to the separate overcurrent protection devices where they are stored in memory. The central tester then broadcasts a test signal which simultaneously initiates testing of all of the overcurrent protection devices using the assigned test currents stored in memory. The trip times are recorded and reported back to the central tester for analysis.
