This senior design project consists of a table top model that replicates an industrial three- phase electrical distribution system, capable of detecting ground faults and measuring load fluctuations in a delta-delta ungrounded transformer configuration. This project seeks to mimic an electrical distribution system operating at 12 kV on the primary and 480 V on the secondary. The model uses smaller nominal voltages consisting of 240 V on the primary and 24 V on the secondary. Current and voltage signals derived from the system connect to a Schweitzer 751-A protective relay which provides the load monitoring and ground fault detection scheme.
