The detection of faults on electrical distribution systems has been one of the most persistent and difficult problems facing the electric utility industry.
The performance and characteristics of electrical system configurations are vital factor in reducing or increasing the effect of faults on the system as earthing
system, switch gear, protective relays, active and reactive power generation, etc.
WHAT ARE THE GOALS?By the end of the course, participants will be able to: ✓ Understand the various types of fault currents ✓ Determine the causes of overcurrent and short circuit current ✓ Explain differences between symmetrical and unsymmetrical faults ✓ Analyse the common faults in a power system ✓ Interpret manual calculation verses software aided fault current calculations
WHO IS THE COURSE FOR?This course is suitable to a wide range of professionals but will greatly benefit: ✓ Electrical Engineers ✓ Electrical Supervisors and Electrical operators engaged in the operation and planning of power
stations ✓ Electrical and Power Engineers ✓ Transmissions and distribution of Electrical Electric Power system . ✓ Engineers / Operators working in electrical control centers. ✓ Participants require a good understanding of electricity and operation and possess some
relevant experience
