PROJECT EXECUTIVE SUMMARY
Engineering Overview
Turnkey design and installation of the complete power distribution network for a 250,000 sq. ft. continuous manufacturing facility. The installation included dual 2.5 MVA dry-type transformers, 5000A Form 4b MDBs, and heavy-duty overhead busbar trunking.
The Challenge
The client required a resilient power system capable of handling extreme non-linear harmonic loads generated by multiple high-tonnage electric arc furnaces and variable speed drive motors without causing equipment overheating.
The Engineering Solution
WIN-TEC engineered custom harmonic-mitigated capacitor banks with 7% detuned reactors, K-factor rated dry transformers, and an intelligent automated power-monitoring SCADA that dynamically tracks THD levels across all sub-circuits.
Key Scope & Technical Deliverables
- 2 x 2500kVA cast resin dry-type transformers and enclosures
- 5000A Form 4b fully segregated Main Distribution Board (MDB)
- Overhead compact sandwich copper busbar trunking (3200A & 1600A)
- Motor Control Centers (MCC) for 45 heavy induction motors
- Emergency automatic synchronizing system for dual 1500kVA diesel generators
Project Results & Impact
