KIPO were appointed by AECOM to provide a full Discrimination Study and report completed using Amtech, with the aim of proposing settings where applicable and any relevant commentary.
Our services and solutions:
Provided a general description of calculation methods, assumptions and base per unit quantities selected
Impedance diagrams, typical calculations, tabulations of calculation quantities and results, conclusions and recommendations
Calculated three phase symmetrical fault currents at each switchboard. Motor control panel and distribution board
Calculated earth fault currents including the associated zero sequence impedance diagram
Detailed MV & LV protection study of all IDMT relays, breakers and fused switches upstream and downstream
Cable sizing optimisation to optimise breaker sizes and trip unit types, having the benefit of further value engineering
After reviewing the sub-main cable sizes, we were able to achieve around 30% reductions in size and potential consequential savings. Our reports covered ‘BS7671 compliance’ with ‘Total Discrimination’ underwritten
