Why
Choose this Training Course?
This
Electrical Faults training course in Dubai teaches practical electrical troubleshooting and is concerned with
the calculation of fault currents in electrical power systems. Short-circuit currents are associated with large
amounts of very destructive energy and therefore calculations must be made to ensure that the short-circuit
ratings of equipment are adequate to cater for these high currents. Accurate assessment of these currents is
also essential for determining the settings of the system protection devices.
This
training course includes the preparation of the system for analysis, by manual calculation and by the use of
computer analysis. Participants will be introduced to the various fault analysis software programs. Also,
all protection device and how to configure the multifunction relay by using relay simulation program will be
included.
This
York Britishtraining course will feature:
Identification
of causes of electrical faults
Understanding
three phase short circuit currents
Recognition
of unsymmetrical faults in transformers
Partial
