The European Low Voltage Directive governs the manufacture or importation of electrical appliances. Compliance with these standards has to be declared and indicated by the display of the CE mark on the product. The responsibility for testing lies with the manufacturer or the importer and is policed by Trading Standards. [1]
A generator using permanent magnets (PMs) is sometimes called a magneto, or a permanent magnet synchronous generator (PMSG). Armature: The power-producing component of an electrical machine. In a generator, alternator, or dynamo, the armature windings generate the electric current, which provides power to an external circuit.
The PSE law (PSE法, PSE hō) is the law that governs electrical appliance safety in Japan. PSE stands for Product Safety Electrical Appliance & Material. The formal name is Denki Yōhin Anzenhō (電気用品安全法). The most recent revision comes April 1, 2001. The PSE symbol can be found on appliances that are approved for use in Japan.
A refrigerating appliance is required to maintain temperatures inside its compartments within specified limits, and to operate (including defrosting) in a specified ambient temperature while using at most a specified amount of electricity; the energy use allowed varies according to volume, number of doors, the function of the various compartments and other parameters.
A standby generator is a back-up electrical system that operates automatically. [1] Within seconds of a utility outage an automatic transfer switch senses the power loss, commands the generator to start and then transfers the electrical load to the generator. The standby generator begins supplying power to the circuits. [2]
A load bank is a piece of electrical test equipment used to simulate an electrical load, to test an electric power source without connecting it to its normal operating load. [ 1 ] [ 2 ] During testing, adjustment, calibration, or verification procedures, a load bank is connected to the output of a power source, such as an electric generator ...
Micro-CHP is defined by the EU as less than 50 kW electrical power output, [1] however, others have more restrictive definitions, all the way down to <5 kWe. [3] A micro-CHP generator may primarily follow heat demand, delivering electricity as the by-product, or may follow electrical demand to generate electricity, with heat as the by-product ...
