| 1. A method of determining the source equivalent inductance of an energized electrical distribution system at a point of measurement
comprising the steps of:
applying a predetermined resistive load to the point of measurement at which time the sinusoidal voltage of the energized
electrical distribution system is near the maximum or minimum peak value;
during applying the predetermined resistive load, measuring the current flowing on the predetermined resistive load, measuring the time required for the measured current to
reach its stabilized peak value;correlating the relationship of the DC resistance applied and source inductance response;
determining the source equivalent inductance of the energized electrical distribution system at the point of measurement based
on the measured current and time and the relationship of DC resistance and inductance transient circuits.
