Substation Design

MEI’s substation design team comprises engineers and designers with varying backgrounds in the electric utility and consulting engineering industries. This collective experience includes design, construction, operations, maintenance, system protection, and apparatus expertise. MEI takes the utilities perspective into account during the substation design process and factors into account the field operations and maintenance of the substation facilities. MEI uses IEEE, ASCE, and NEMA standards to provide a proven design basis for every substation design project. Other industry accepted practices by organizations such as the RUS Substation Design Guide are applied. With more than thirty-five years of experience directly related to power transformer procurement, quality assurance, maintenance practices, condition assessments, and forensic analysis, our services are available to assist clients with matters related to their power transformers. We use AutoCAD on substation design projects to verify clearances, working space, and drawing accuracy. All drawings are reviewed and approved by a licensed professional engineer prior to issuing for construction.
