- Course 146.
- 1 Week.
- 2.4 CEU.
This coordination study is an essential element of an arc flash study and is intended for engineers, supervisors and relay technicians that are responsible for the protection of industrial power systems.

The goal of protective device coordination is to allow for normal equipment operation, ensure circuits open before equipment is damaged and limit outages to the smallest area through selectivity.
These studies are used to verify correct equipment ratings and settings as well as assist in the selection of new equipment. A properly coordinated power system can prevent equipment damage and lost productivity.
The course will be covering:
• Identify and explain the application of common power studies including short circuit, load flow, stability, motor starting, harmonic analysis, switching transient, cable ampacity, ground mat analysis, arc flash analysis and protective.
• device coordination.
• Explain the application of fuses, low-voltage breakers and motor overload and overcurrent relays.
• Utilize SKM PTW to create and modify one line drawings and time current.
• coordination curves (TCCs).
• Interpret TCCs and damage curves.
• Coordinate protective devices to prevent thermal and mechanical damage to transformers, cables, and motors utilizing SKM PTW software.
Who Should Attend
This coordination study is also an essential element of an arc flash study and is intended for engineers, supervisors and relay technicians that are responsible for the protection of industrial power systems. The class participant should have basic knowledge of power system equipment and mathematics.
