During the operation of the electrical power system (SEP), there are often protection failures that can result in shutdowns in the power supply, causing a reduction in quality of service. This is not common, but it happens ...

This work presents a study of electrical power systems protective functions, focusing on computer modeling of each of functions discussed on the course of the work. It is very important that the protection system operates ...

Electrical installations in industries involving high currents and voltages considered. On the other side is the common appearance of electrical failures, caused by human error, defects in electrical equipment or electrical ...

Large electric motors require greater care when driving, especially during continuous operation since they are part of day-to-day manufacturing sector, acting essentially to ensure that no damage occurs to the production ...
