In electric power distribution, automatic circuit reclosers (ACRs) are a class of switchgear designed for use on overhead electricity distribution networks to detect and interrupt transient faults. Also known as reclosers or autoreclosers , ACRs are essentially rated circuit breakers with integrated current and voltage sensors and a protection ...
In electric power systems and industrial automation, ANSI Device Numbers can be used to identify equipment and devices in a system such as relays, circuit breakers, or instruments. The device numbers are enumerated in ANSI / IEEE Standard C37.2 Standard for Electrical Power System Device Function Numbers, Acronyms, and Contact Designations .
Reclosers are not the only automatic reclosing devices on distribution ciruits; however they can greatly improve overall system reliability by decreasing the amount of customers experiencing an outage for a given fault. — Preceding unsigned comment added by Greyphox (talk • contribs) 03:42, 18 January 2012 (UTC)
Other standard features include automatic reclosing circuit breakers . Most faults (overcurrent) are transient. Since the network is rural, most of these faults will be cleared by the recloser. Each service site needs a rewirable drop out fuse for protection and switching of the transformer.
Power-system automation is the act of automatically controlling the power system via instrumentation and control devices.Substation automation refers to using data from Intelligent electronic devices (IED), control and automation capabilities within the substation, and control commands from remote users to control power-system devices.
A machine gun conversion device for a Glock hand gun can convert the Glock into a machine gun after the "switch" is installed. It can be made with a 3-d printer.
