LV and MV Distribution Design
Medium-voltage and low-voltage distribution design determines the efficiency, safety, and reliability of power delivery to industrial plants, commercial centers, university campuses, and residential developments. MEPCO engineers robust distribution networks, package substations, motor control centers (MCC), cable raceways, and emergency backup generation.

Technical Scope & Engineering Capabilities
MEPCO Engineering Projects brings specialized domain knowledge, rigorous modeling standards, and practical site experience to every assignment. Our scope covers:
- Medium-Voltage Ring Network Design: Designing 11 kV, 22 kV, and 33 kV open-loop and closed-ring distribution topologies with Ring Main Units (RMU) for high supply reliability.
- Distribution Substation Sizing: Sizing and specifying indoor and outdoor package substations, step-down transformers, and MV switchgear cubicles.
- Low-Voltage Distribution Boards: Designing Main Low-Voltage Distribution Boards (MLVDB), sub-distribution boards, Motor Control Centers (MCC), and panelboard schedules.
- Cable Containment & Raceway Layouts: Detailed 3D routing of cable trays, ladders, trenches, and underground duct banks with full separation of power and control circuits.
- Emergency Standby Power Systems: Sizing diesel generators, Uninterruptible Power Supply (UPS) systems, Automatic Transfer Switches (ATS), and central battery systems.
- Power Factor Correction & Efficiency: Sizing automatic capacitor banks with detuned reactors to maintain power factor above 0.95 and reduce utility penalty charges.
Software Platforms & Computational Tools
Design Platforms: AutoCAD, Autodesk Revit MEP, ETAP for distribution calculations.
Applicable Standards & Grid Codes
Distribution Codes: IEC 60364 series (Low-voltage electrical installations), IEC 61439, local electricity distribution company regulations.
Methodology & Project Delivery Workflow
Our engineering delivery aligns with MEPCO’s structured 6-stage project execution framework, ensuring quality throughout input verification, design modeling, and client handover:
- Stage 01 — Scope & Criteria Definition: Establish study boundaries, utility tie-in data, single-line diagrams, and client objectives.
- Stage 02 — Data Audit & Modeling Assumptions: Collect, verify, and validate manufacturer datasheets, impedance tolerances, and site operating configurations.
- Stage 03 — Simulation Model Development: Build detailed, validated mathematical digital models in specialized power software.
- Stage 04 — Computational Analysis & Verification: Execute base-case and contingency scenarios, conducting rigorous internal peer reviews.
- Stage 05 — Client Review & Approval: Present study findings, address technical comments, and participate in technical clarification sessions.
- Stage 06 — Final Handover: Deliver formal certified engineering reports, executive summaries, and native simulation model files.
