SAMPLE COURSES
The objective of this module is to review, for the benefit of relay personnel, the responsibilities of the power system operators and the activities that take place in the energy control center. The operation of protection schemes is of vital importance to the correct functioning of the power system. Complete cooperation between power system operators and relay personnel is essential, and communication must be maintained in both directions.
