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
