208V vs. 480V & 208V Distribution System Analysis

Purpose

 Analysis of alternative power distribution system based on first cost and efficiency  In conjunction with the Construction Management Breadth

Existing System

 (2) transformers, 2500 kVA-480V Multifunction floors, 1000 kVA-208V Residential

Redesigned System

 (1) 3750 kVA-208V Transformer

Analysis Method

 Reconfiguration and resizing of electrical equipment and system paths  Relocation of equipment (not included)  Cost analysis
