@SkyWhisperer - We sell database software and electrical utilities are among our customers. What they do is take all of the substation information, along with the relays, transformers, and circuit breakers – basically any device that they want – and import it into the software.
They also use the database to store results from electrical safety testing that they’ve performed on substation equipment; primarily this would be relay equipment but it includes tests on other devices such as transformers and circuit breakers.
The reason that it’s so important is that government auditors will come from time to time and have them verify that the equipment is in proper working order. Our software will produce reports of the last test times, and test results. If they were to fail the audit, they could be hit with million dollar fines.
