  • Method of configuring a microprocessor-based relay for use in overcurrent protection
    Patent number: 5987393
    Abstract: A system for generating a time overcurrent curve from a set of time and current inputs. The overcurrent curve is generated by simultaneously finding four coefficients of a standard overcurrent equation. Two of the coefficients are found by successive approximation and two of the coefficients are found via a least squares fit approximation. After the coefficients are found, they are used in the standard overcurrent equation to produce a set of data points indicative of the overcurrent curve. The data points are transferred to an overcurrent relay for the detection of overcurrent conditions.
