According to one aspect, embodiments described herein provide a system and a method for managing an electrical distribution system for a facility having at least one load. In one example, the method comprises receiving data related to transfer performance of a plurality of energy sources in the electrical distribution system, the plurality of energy sources including a first energy source and a second energy source, converting the data into transfer parameter values, receiving predefined transfer performance indicators related to the plurality of energy sources in the electrical distribution system, comparing the transfer parameter values with predefined transfer performance indicators to produce a comparison result assessing transfer performance of the plurality of energy sources, and managing transfer of the at least one load between the first energy source and the second energy source based on the comparison result.

Systems and methods of monitoring bridging time

An automated emergency power supply system (EPSS) and testing solution that records generator load values and engine exhaust temperature values to evaluate whether an EPSS test satisfies legislated test criteria. The EPSS test is carried out under software control, which initiates a test by instructing an automatic transfer switch (ATS) to change its status to a test status, causing the essential loads to be powered by a generator instead of a main utility power source. Power monitors record the ATS and generator status during the test as well as electrical parameter data from the ATS and generator and exhaust temperature data and other engine parameter data from the generator. When the test is concluded, the ATS is instructed to return the status to normal so that power delivery is resumed from the main power source. The electrical and engine parameter data is analyzed and compared against legislated test criteria to determine a pass/fail result of the EPSS test.
