In 1992, Black & Decker began a major effort to rebrand its professional quality and high-end power tools to DeWalt. In 1994, DeWalt took over the German woodworking power tool producer ELU, and used ELU's technology to expand their tool line. As of 2001, they manufacture and sell more than 200 hand power tools and 800 accessories. [2]
A 115 kV high-voltage fuse in a substation near a hydroelectric power plant Older medium-voltage fuse for a 20 kV network. These type of fuses may have an impact pin to operate a switch mechanism, so that all three phases are interrupted if any one fuse blows. High-power fuse means that these fuses
In electrical distribution, a fuse cutout or cut-out fuse (often referred to as a cutout) is a combination of a fuse and a switch, used in primary overhead feeder lines and taps to protect distribution transformers from current surges and overloads. An overcurrent caused by a fault in the transformer or customer circuit will cause the fuse to ...
The AC output voltage of a power inverter is often regulated to be the same as the grid line voltage, typically 120 or 240 VAC at the distribution level, even when there are changes in the load that the inverter is driving. This allows the inverter to power numerous devices designed for standard line power.
A distribution board (also known as panelboard, circuit breaker panel, breaker panel, electric panel, fuse box or DB box) is a component of an electricity supply system that divides an electrical power feed into subsidiary circuits while providing a protective fuse or circuit breaker for each circuit in a common enclosure.
Inverter generators are best to power sensitive electronic devices such as computers and lights that use a ballast, as they have a low total harmonic distortion. Since the load on the electric generator causes the speed of the engine to fall, this has an adverse effect on the frequency and voltage of the electrical output.
An antifuse is an electrical device that performs the opposite function to a fuse.Whereas a fuse starts with a low resistance and is designed to permanently break or open an electrically conductive path (typically when the current through the path exceeds a specified limit), an antifuse starts with a high resistance—an open circuit—and programming it converts it into a permanent ...
The One Watt Initiative is an energy-saving initiative by the International Energy Agency (IEA) to reduce standby power-use by any appliance to no more than one watt in 2010, and 0.5 watts in 2013. The initiative has given rise to regulations in many countries and regions.
