The electrical power field is concerned with the generation, transmission, and
distribution of electrical energy. Electrical power engineers design and develop
equipment and systems to provide electricity in homes, offices, stores, and factories.
The equipment includes devices to regulate the frequency and voltage of the power
delivered to consumers, to correct its power factor, and to protect the network and its
customers from lightning strikes, surges, and outages. Many power engineers design
power systems for aircraft and spacecraft; others provide computer-controlled energy
management systems that conserve energy in manufacturing facilities; and still others
design electrical motors for applications ranging from appliances to processing plants.
