APERÇU

After completion of this course, the participant will be able to:

• Model electrical power system using Easy Power
• Run the power flow calculation to identify the undersized equipment and bus under-voltage
• Run short circuit calculation and equipment duty to identify if there is equipment which cannot withstand the maximum short circuit power
• Run protection coordination and provide the optimum setting of the protection relays to achieve the best protection and coordination
• Run arc flash calculation, using NFPA 70E or IEEE1584 to identify the arc energy when working on power on an electrical system and the required PPE

Description
Today's society relies heavily on electrical energy. Generation, transmission and distribution are forming the BULK electrical system.

The electrical power system is vital for all industrial segments and residential consumers. In this course, the participant will learn how to build an electrical model for an existing system or use the generic model for the study of a new system. All possible normal operation and abnormal operation configurations can be evaluated to provide fundamental support for the optimization of the electrical power system configuration.
