Power-system protection is a branch of electrical power engineering that deals with the protection of electrical power systems from faults through the isolation of faulted parts from the rest of the electrical network.

The objective of a protection scheme is to keep the power system stable by isolating only the components that are under fault, whilst leaving as much of the network as possible still in operation.

Thus, protection schemes must apply with very and pessimistic approach to clearing system faults.

The devices that are used to protect the power systems from faults are called protection devices.

Schweitzer Engineering Laboratories, Inc. (SEL) designs, manufactures, and supports products and services ranging from generator and transmission protection to distribution automation and control systems.

Founded in 1982 by Edmund O.

Schweitzer III, SEL shipped the world's first digital protective relay.

Presently, the company designs and manufactures embedded system products for protecting, monitoring, control, and metering of electric power systems.

Automation or automatic control, is the use of various control systems for operating equipment such as machinery, processes in factories, boilers and heat treating ovens, switching on telephone networks, steering and stabilization of ships, aircraft and other applications and vehicles with minimal or reduced human intervention.

Some processes have been completely automated.

A system is a set of interacting or interdependent component parts forming a complex or intricate whole.

Every system is delineated by its spatial and temporal boundaries, surrounded and influenced by its environment, described by its structure and purpose and expressed in its functioning.

Electric power is the rate, per unit time, at which electrical energy is transferred by an electric circuit.

The SI unit of power is the watt, one joule per second.
