Power plant operators, dispatchers, and distributors control the systems that generate and distribute electric power.

Power plant operators, distributors, and dispatchers typically do the following:

• Control power-generating equipment, such as boilers, turbines, generators, and reactors
• Read charts, meters, and gauges to monitor voltage and electricity flows
• Check equipment and indicators to detect evidence of operating problems
• Adjust controls to regulate the flow of power
• Start or stop generators, turbines, and other equipment as necessary

Electricity is one of our nation's most vital resources. Power plant operators, distributors, and dispatchers control power plants and the flow of electricity from plants to substations, which distribute electricity to businesses, homes, and factories. Electricity is generated from many sources, including coal, gas, nuclear energy, hydroelectric energy (from water sources), and wind and solar power.

The following are types of power plant operators, distributors, and dispatchers:

Nuclear power reactor operators control nuclear reactors. They adjust control rods, which affect how much electricity a reactor generates. They monitor reactors, turbines, generators, and cooling systems, adjusting controls as necessary. Operators also start and stop equipment and record the data. They may need to respond to abnormalities, determine the cause, and take corrective action.

Power distributors and dispatchers, also known as systems operators, control the flow of electricity as it travels from generating stations to substations and users over a network of transmission and distribution lines. They prepare and issue switching orders to route electrical currents around areas that need maintenance or repair. Distributors and dispatchers also monitor and operate current converters, voltage transformers, and circuit breakers. They must detect and respond to emergencies, such as transformer or transmission line failures.

Power plant operators control, operate, and maintain machinery to generate electric power. They use control boards to distribute power among generators and regulate the output from several generators. They regulate the flow of power between generating stations and substations, and they monitor instruments to maintain voltage and electricity flows from the plant.

Electrical and electronics installers and repairers install, repair, or replace a variety of electrical equipment in telecommunications, transportation, utilities, and other industries.

Electrical and electronics installers and repairers typically do the following:

• Prepare cost estimates for clients
• Refer to service guides, schematics, and manufacturer specifications
• Repair or replace defective parts, such as motors, fuses, or gaskets
• Reassemble and test equipment after repairs
• Maintain records of parts used, labor time, and final charges

Electrical and electronics installers and repairers work on complex pieces of electronic equipment.

Automated electronic control systems are becoming increasingly complex. As a result, repairers use software programs and testing equipment to diagnose malfunctions. Among their diagnostic tools are multimeters--which measure voltage, current, and resistance--and advanced multimeters, which measure the capacitance, inductance, and current gain of transistors.

Repairers also use signal generators, which provide test signals, and oscilloscopes, which display signals graphically. In addition, repairers use handtools such as pliers, screwdrivers, soldering irons, and wrenches to replace faulty parts and adjust equipment.

Commercial and industrial equipment electrical and electronics repairers repair, test, adjust, or install electronic equipment, such as industrial controls, transmitters, and antennas.

Electrical and electronics installers and repairers of transportation equipment install, adjust, or maintain mobile communication equipment, including sound, sonar, security, navigation, and surveillance systems on trains, watercraft, or other vehicles.

Powerhouse, substation, and relay electrical and electronics repairers inspect, test, maintain, or repair electrical equipment used in generating stations, substations, and inservice relays. These workers may be known as powerhouse electricians, relay technicians, or power transformer repairers.

Electric motor, power tool, and related repairers--such as armature winders, generator mechanics, and electric golf cart repairers--specialize in installing, maintaining, and repairing electric motors, wiring, or switches.

Electronic equipment installers and repairers of motor vehicles install, diagnose, and repair sound, security, and navigation equipment in motor vehicles. Motor vehicle installers and repairers work with an increasingly complex range of electronic equipment, including DVD players, navigation systems, and passive and active security systems.

Electrical and electronic installers and repairers may specialize, according to how and where they work:

Field technicians often travel to factories or other locations to repair equipment. When equipment breaks down, field technicians go to a customer's site to repair the equipment. Because repairing components is a complex activity, workers on the factory floor usually remove and replace defective units, such as circuit boards, instead of fixing them. Defective units are discarded or returned to the manufacturer or a specialized shop for repair.

Bench technicians work in repair shops in factories and service centers, fixing components that cannot be repaired on the factory floor. These workers also locate and repair circuit defects, such as poorly soldered joints, blown fuses, or malfunctioning transistors.

Electricians install and maintain electrical systems in homes, businesses, and factories.

Electricians typically do the following:

• Read blueprints or technical diagrams before doing work
• Install and maintain wiring and lighting systems
• Inspect electrical components, such as transformers and circuit breakers
• Identify electrical problems with a variety of testing devices
• Repair or replace wiring, equipment, or fixtures using hand tools and power tools
• Follow state and local building regulations based on the National Electric Code
• Direct and train workers to install, maintain, or repair electrical wiring or equipment

Almost every building has an electrical system that is installed during construction and maintained after that. Electricians do both the installing and maintaining of electrical systems.

Installing electrical systems is less complicated than maintaining older equipment. This is because it is easier to get to electrical wiring during construction. Maintaining older equipment, however, involves identifying problems and repairing malfunctioning equipment that is sometimes difficult to reach. Electricians doing maintenance work may need to fix or replace outlets, circuit breakers, motors, or robotic control systems.

Electricians read blueprints, which are technical diagrams of electrical systems that show the location of circuits, outlets, and other equipment. They use different types of hand and power tools, such as pipe benders, to run and protect wiring. Other commonly used hand and power tools include screwdrivers, wire strippers, drills, and saws. While troubleshooting, electricians also may use ammeters, voltmeters, and multimeters to find problems and ensure that components are working properly.

Many electricians work independently, but sometimes they collaborate with others. For example, experienced electricians may work with building engineers and architects to help design electrical systems in new construction. Some electricians also may consult with other construction specialists, such as elevator installers and heating and air conditioning workers, to help install or maintain electrical or power systems. At larger companies, electricians are more likely to work as part of a crew; they may direct helpers and apprentices to complete jobs.

The following are examples of occupational specialties:

Inside electricians maintain and repair large motors, equipment, and control systems in businesses and factories. They use their knowledge of electrical systems to help these facilities run safely and efficiently. Some also install the wiring for businesses and factories that are being built. To minimize equipment failure, inside electricians often perform scheduled maintenance.   

Residential electricians install wiring and troubleshoot electrical problems in peoples' homes. Those who work in new-home construction install outlets and provide access to power where needed. Those who work in maintenance and remodeling repair and replace faulty equipment. For example, if a circuit breaker is tripped, electricians determine the reason and fix it.

Electrical engineers design, develop, test, and supervise the manufacturing of electrical equipment such as electric motors, radar and navigation systems, communications systems, or power generation equipment. Electrical engineers also design the electrical systems of automobiles and aircraft.

Electronics engineers design and develop electronic equipment such as broadcast and communications systems, from portable music players to global positioning systems (GPS). Many also work in areas closely related to computer hardware.

Electrical engineers typically do the following:

• Design new ways to use electrical power to develop or improve products
• Do detailed calculations to compute manufacturing, construction, and installation standards and specifications
• Direct manufacturing, installing, and testing to ensure that the product as built meets specifications and codes
• Investigate complaints from customers or the public, evaluate problems, and recommend solutions
• Work with project managers on production efforts to ensure projects are completed satisfactorily, on time, and within budget

Electronics engineers typically do the following:

• Design electronic components, software, products, or systems for commercial, industrial, medical, military, or scientific applications
• Analyze electrical system requirements, capacity, cost, and customer needs and then develop a system plan
• Develop maintenance and testing procedures for electronic components and equipment
• Evaluate systems and recommend repair or design modifications
• Inspect electronic equipment, instruments, and systems to make sure they meet safety standards and applicable regulations
• Plan and develop applications and modifications for electronic properties used in parts and systems to improve technical performance

Electronics engineers who work for the federal government research, develop, and evaluate electronic devices used in diverse technologies, such as aviation, computing, transportation, and manufacturing. They work on federal electronic devices and systems, including satellites, flight systems, radar and sonar systems, and communications systems.

The work of electrical engineers and electronics engineers is often similar. Both use engineering and design software and equipment to do engineering tasks. Both types of engineers must also work with other engineers to discuss existing products and possibilities for engineering projects.

Engineers whose work is related exclusively to computer hardware are considered computer hardware engineers. For more information about this occupation, see the profile on computer hardware engineers.

Computer, ATM, and office machine repairers install, fix, and maintain many of the machines that businesses, households, and other consumers use.

Computer, ATM, and office machine repairers typically do the following:

• Travel to customers' locations in response to service requests
• Communicate with customers to determine the source of a problem
• Do administrative tasks, such as completing work order forms
• Use a variety of tools, such as a multimeter, to help diagnose the problem
• Install large equipment, such as mainframe computers and ATMs
• Explain the basic functions of machines and equipment to customers
• Replace malfunctioning machine parts, such as video cards in desktop computers or keypads on ATM machines
• Provide preventative maintenance, such as cleaning the internal parts of machines
• Test newly installed systems to make sure they work properly

In most cases, machines do not break down entirely. Often just one broken part can keep a machine from working properly. Repairers often fix machines by replacing these parts and other defective equipment because it is often less expensive than replacing the entire machine.

Although the work of computer, ATM, and office machine repairers is very similar, the exact tasks differ depending on the type of equipment. For example, computer repairers often must replace desktop parts, such as a motherboard, because of hardware failure. ATM repairers may replace a worn magnetic head on a card reader to allow an ATM to recognize customers' bank cards. Office machine repairers replace parts of office machines that break down from general wear and tear, such as the printheads of inkjet printers.

Some repairers have assigned areas where they do preventive maintenance on a regular basis.

Computer repairers service and repair computer parts, network connections, and computer equipment, such as an external hard drive or computer monitor. Computer repairers must be familiar with various operating systems and commonly used software packages. Some work from repair shops, while others travel to customers' locations.

ATM repairers install and repair automated teller machines and, increasingly, electronic kiosks. They often work with a network of ATMs and travel to ATM locations when they are alerted to a malfunction.

Office machine repairers fix machinery at customers' workplaces because these machines are often large and stationary, such as office printers or copiers. Office machines often need preventive maintenance, such as cleaning, or replacement of commonly used parts as they break down from general wear and tear.
