Automated Heavy Manufacturing Power Distribution

Biyagama Export Processing Zone • Completed 2023

Automated Heavy Manufacturing Power Distribution

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.
