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 ...
Vehicle lights provided the only illumination during the 2009 Ecuador electricity crisis.. A power outage, also called a powercut, a power out, a power failure, a power blackout, a power loss, a blackout or a power drought — is the loss of the electrical power network supply to an end user.
On a 3-phase circuit, a recloser is more beneficial than three separate fuse cutouts. For example, on a wye to delta conversion, when cutouts are used on the wye side and only 1 out of 3 of the cutout fuses open, some customers on the delta side have a low voltage condition, due to voltage transfer through the transformer windings. Low voltage ...
The clearing I 2 t is proportional to the total energy let through by the fuse when clearing a fault. The energy is mainly dependent on current and time for fuses as well as the available fault level and system voltage. Since the I 2 t rating of the fuse is proportional to the energy it lets through, it is a measure of the thermal damage from ...

Both filings with the California Public Utilities Commission lay bare parts of the major grid that powers Southern California, and spell out power line surges, malfunctions and other "faults" that ...
Utility provider Southern California Edison on Monday evening cut electricity to another 105 homes in a section of Rancho Palos Verdes known as Seaview for "varying lengths of time" — some to go ...
In 1908, the company was renamed Detroit Fuse and Manufacturing. Horton, an 1895 electrical engineering graduate of the University of Michigan , was credited with the invention of the safety switch, which encased high voltage switches and started the company's main line of business of circuit breakers and encased control panels.
