Plug load is the energy used by products that are powered by means of an ordinary AC plug (e.g., 100, 115, or 230 V). [1] This term generally excludes building energy that is attributed to major end uses ( HVAC , lighting , water heating , etc.) [ 1 ]
The plotted line represents the variation of instantaneous voltage (or current) with respect to time. This cycle repeats with a frequency that depends on the power system. In electrical engineering, three-phase electric power systems have at least three conductors carrying alternating voltages that are offset in time by one-third of the period ...
Three-phase electric power (abbreviated 3ϕ [1]) is a common type of alternating current (AC) used in electricity generation, transmission, and distribution. [2] It is a type of polyphase system employing three wires (or four including an optional neutral return wire) and is the most common method used by electrical grids worldwide to transfer ...
Because the BS 1363 plug contains a fuse not exceeding 13A, the load at any one point on the ring is limited. The IET Wiring Regulations ( BS 7671 ) permit an unlimited number of 13A socket outlets (at any point unfused single or double, or any number fused) to be installed on a ring circuit, provided that the floor area served does not exceed ...
The term plug is in general and technical use in all forms of English, common alternatives being power plug, [1] electric plug, [2] and (in the UK) plug top. [3] The normal technical term (in both British and International English) for an AC power socket is socket-outlet, [4] but in non-technical common use a number of other terms are used.
MELs are produced by hard-wired and “plug-in” electrical devices that draw power, including office equipment such as desktop computers and monitors, mobile electronics (laptops, tablets, mobile phones, and their charging units), printers, fans, task lighting, and home equipment such as home entertainment centers, kitchen electronics ...
An electrical load is an electrical component or portion of a circuit that consumes (active) electric power, [1] [2] such as electrical appliances and lights inside the home. The term may also refer to the power consumed by a circuit. This is opposed to a power supply source, such as a battery or generator, which provides power. [2]
In power engineering, the power-flow study, or load-flow study, is a numerical analysis of the flow of electric power in an interconnected system. A power-flow study usually uses simplified notations such as a one-line diagram and per-unit system, and focuses on various aspects of AC power parameters, such as Voltage, voltage angles, real power and reactive power.
