Important Electrical Power System Terms
Electrical power systems are an essential part of residences and businesses. If your electrical system requires maintenance, a skilled contractor can get things up and running efficiently. The following are some helpful terms to be familiar with when hiring a professional to work on your electrical system:
Generator: A generator is a machine used in an electrical system to convert mechanical energy into electricity. Generators are an essential component in power plants used to supply the network of buildings on the power grid. Independent backup generators are often installed in hospitals, homes, and businesses in case of a power failure.
AC Power: AC stands for alternating current, referring to the direction the electrical current flows. AC power currents reverse direction periodically. This type of current is the one transmitted to home outlets throughout the electrical network.
DC Power: DC, or direct current, power flows continuously in one direction. A battery provides a supply of DC power. Also, AC power can be converted to DC inside appliances like computers with the right electrical components.
Electrical Conductors: An electrical conductor is a material that can carry an electrical current. Many materials can carry electrical currents. One of the most commonly used conductors in electrical systems is copper wire.
Load: Loads are electrically powered devices that receive energy from an electrical system to perform their function. Loads can be commercial and industrial machinery as well as common household appliances, like microwaves and vacuum cleaners.
Photovoltaic Cell: A photovoltaic cell, also known as a solar cell, is a device that converts sunlight into electrical energy. These cells are used to build solar panels for homes, businesses, and utility providers. They provide renewable energy and, unless damaged, require very little maintenance.
Electrical power systems maintenance companies provide commissioning, start up, and maintenance testing for a variety of industries and applications, including utility, industrial, governmental, transit, commercial, residential, and high-tech. Such companies are made up of engineering and other professionals, who test and maintain transformers, circuits, wiring, grounding, voltage, breakers, generators, switches, and plugs. Electrical power systems maintenance companies may also provide installation, relay and meter calibration, distribution, system protection, oil and gas reclamation, cable and fault location, power circuit breaker testing, AC and DC hi-potential testing, and generator load and systems testing. Some professionals work for large electrical power systems maintenance corporations, while others work as private consultants. Target your search to companies that offer exactly what you need, whether for residential, commercial, or industrial applications. You can find electrical power systems maintenance companies by looking in your local phone book or by searching online directory listings. You may also want to get word-of-mouth recommendations by others in your line of business as to which electrical power systems maintenance consultants they use and trust. Consider what your need is, whether it involves grounding, equipment testing, or transformers. Transformers are devices designed to transfer electric energy from one circuit to another, leading to a change in voltage or current. Transformers can be found in power grids, autos and other such machinery. Consider your budget and stick to it. Research the various types of quality electrical power systems maintenance services out there and which ones best suit your needs. Research rates as well, so you know what to include in your budget.
