Electrical Design Calculations and Consideration Unit 3: Three-phase circuit with power factor - Pre-order Only
This unit explores some additional design principles, including power factor and three-phase circuits plus the use of steel-wire armoured cable.
All prices shown are exclusive of VAT which will be added at checkout.
This course is available for pre-order. The course will be made available soon.
The course has been written by Simon Ogborn FIET MSET LCGI, owner and lecturer at Erudite Training Ltd.
Simon has been an electrical engineer for over thirty years, primarily working on critical power supplies within petrochemical plants. After attending college in 2004 to take his Design and Verification qualification, in which he attained a Distinction, he was asked to join the teaching team at Tameside College. Simon started Erudite Training in 2009 with the primary ethos being to teach the subject properly, not just coach for exams. This, in turn lead Simon to be head hunted by City and Guilds, in 2013, to become one of their Technical Consultants.
Simon has been involved in many of the electrical qualifications since then, including working on the 2396 Level 4 Design and Verification. He is therefore ideally placed with technical understanding, teaching skills and the valuable insight into what errors candidates make in their exams.
• Access and understand the relevant regulations pertaining to this design element.
• Understand the principles of power factor as applied to cable current carrying capacity.
• Be able to apply power factor to voltage drop calculations dependent on cable size.
• Calculate the earth fault loop impedance of circuits using steel wire armoring as a protective conductor.
• Confirm earth fault thermal constraints where steel wire armoring is used a s protective conductor.
• Understand fixing requirements for cables for mechanical and fire durability.
