As an operator you know your job extremely well through training and experience. You know exactly what buttons to push, knobs to turn, and indicators to view to parallel the generator to the grid. In performing these tasks, is there a comprehension of why these tasks have to be done in a certain way and sequence? Is there a big picture of how all the components that make up the electrical side of the power plant are linked together such that power is generated and sent to the grid?

Once the generator is on line, what are the factors affecting the power output of the generator? Are these factors strictly mirroring the characteristics of the load? How are these factors being addressed either manually or automatically?

What electrical sensors are used in a variety of ways through instrumentation to monitor and protect the operation of the electrical equipment?
Do you know how to read an electrical schematic? What do the symbols on the schematic mean? Is there a way to understand the predictability of an electrical circuit?

These questions along with many more will be answered upon attending the Electrical Systems For Operators Seminar.
