SEL Relay Settings Database Conversion – Provided MID consulting engineering services for the conversion of SEL protective relay settings from 5010 database to 5030 database. Scope of services include download of nearly 1000 SEL relays at over 35 substations and power plants with settings comparisons made to MID engineering documentation (relay settings) and as-found settings. Settings differences were analyzed and recommendations made to MID discrepancies arose.
