Course Introduction: Distribution Networks are designed to serve loads in a safe and reliable manner. One of the major considerations in the design of any power network is adequate control of. If short-circuits (faults) are not controlled they can cause unnecessary loss of electricity service with all of its many ramifications and damage to equipment. Faults on system elements are removed from networks by means of equipment referred to as Power System Protection. By popular request this 5-day course has been specifically designed with joint co-operation between CYME and ICTD to address protection co-ordination requirements for both power distribution utilities and industrial companies with distribution power networks in the Gulf States. This is the third of a series of four courses intended to provide important knowledge and study skills necessary for both designers and operators of power distribution networks. Course Objectives: Towards the end of the training, the participants will be able to: Learn the Principles of Protection Co-ordination Be able to apply appropriate software for the purposes of optimizing the design of protection schemes Learn up-to-date practices in the field of protection design and co-ordination to achieve maximum security at minimum cost. Be able to study their existing and future networks for possible improvements in protection Who Should Attend? Attendees should be able to handle personal computer interfaces in Microsoft Windows. Course Outline: Module (01) Faults and Fault Levels The reasons for faults Distinction between load current and fault current Sources of short-circuit current Symmetrical and asymmetrical currents X/R ratio and the DC component How to calculate fault currents in power networks Principles of Circuit Breakers, Reclosers and Fuses Measurement transformers (PT s and CT s) EE REVISION 001 PAGE 2 OF 6
