D.G Size Calculation (22.8.12)

This document contains technical specifications for equipment and calculations related to sizing an emergency diesel generator set. It lists the voltage ratings, connected loads including motor loads, and load factors. Calculations determine the starting and running load requirements, recommended generator size, and estimates of fuel consumption and operating costs. The generator is sized to 237kVA to meet the starting load of 237kVA and running load of 81kVA while maintaining an efficiency of 63% at full load operation.
