Company Profile:
An electrical installation containing power conversion (and sometimes generation) equipment, such as transformers, compensators, and circuit breakers.
Industry:Energy
An electrical inverter that inverts direct current electricity to alternating current electricity, and that uses another alternating current source, such as an electric power transmission and distribution network (grid), for voltage and frequency reference to provide power in phase and at the same frequency as the external power source.
Industry:Energy
An electrical load used to safely use excess generated power when not needed for its primary uses. A shunt load in a residential photovoltaic system might be domestic water heating, such that when power is not needed for typical building loads, such as operating lights or running HVAC system fans and pumps, it still provides value and is used in a constructive, safe manner.
Industry:Energy
ion
An electrically charged atom or group of atoms that has lost or gained electrons; a loss makes the resulting particle positively charged; a gain makes the particle negatively charged.
Industry:Energy
An electricity generating facility that uses geothermal energy.
Industry:Energy
An electricity powered device that extracts available heat from one area (the heat source) and transfers it to another (the heat sink) to either heat or cool an interior space or to extract heat energy from a fluid.
Industry:Energy
An electricity supplier rate structure in which the per unit price of electricity decreases as the amount of energy increases. Normally only available to very large consumers.
Industry:Energy
An electrochemical battery that uses lead and lead oxide for electrodes and sulfuric acid for the electrolyte.
Industry:Energy
An electrochemical device that converts chemical energy directly into electricity.
Industry:Energy
An electromagnetic ballast that disconnects a lamp's electrode heating circuit once is has started; often called "low frequency electronic" ballasts.
