Power and ElectricalElectrical Power Distribution and Protection Coordination
A three day course on designing an industrial distribution network and setting the protection that makes it selective. Delegates work through medium and low voltage system design, fault current and short circuit calculation, and the selection of relays, fuses and circuit breakers for each part of a network. Coordination is the heart of the course: delegates build and interpret time current grading curves, so that a fault clears at the device nearest to it rather than tripping half the plant. Earthing, bonding and system grounding are covered as design decisions with direct safety consequences, and the course closes on switchgear selection and protection testing, addressing the switchgear and coordination problems commonly found on industrial sites across the region.
