Case Study: Motor Oil Hellas achieves greater power system reliability with SEL POWERMAX

Automated Power Management System An Economical Approach to Greater Operational Dependability

Motor Oil Hellas Corinth Refineries S.A. (MOH), the largest privately held industrial complex in Greece, needed a more reliable and economical way to manage its growing on-site power generation and electrical distribution systems. Its older electromechanical relay-based protection scheme was slow, hard to troubleshoot, not very selective, and difficult to maintain across many different devices and generations. MOH turned to Schweitzer Engineering Laboratories (SEL) and its POWERMAX Power Management and Control System.

SEL designed and installed the POWERMAX system to integrate protection, load shedding, generation control, monitoring, diagnostics, and data archiving across the refinery’s power network. The solution was fully simulated before commissioning, which helped avoid misoperations on the 70,000-tag system. According to MOH, the new system improved electrical reliability, standardized equipment and training, and repeatedly helped prevent losses of major transformers and motors while allowing the team to make modifications themselves.
