Switchgear requirements get even more complex based on the type of system required.
Switchgear and generator software allow for automatic generator paralleling.When generators are up to speed and rated power, ATS switches to emergency generator power.ATS commands the generators to be started.All utility power is lost to multiple generator automatic transfer switches.An example of a typical power loss is listed below: Power distribution panels can be high voltage and have sub-panels equipped with step-down transformersĬonnected for low voltage operation. Of a brown out or complete loss of power. Multiple emergency generators can be paralleled and placed on-line in the event The control room is the center hub for electrical power distribution. Large installations with critical power requirements can have a control room. These systems are custom designed by power enginners for the facility. Hospitals, aerospace facilities, data centers and other industries that require continuous power when utility power is interrupted employ more advanced switchgear systems. Alarm and Monitoring - Fire monitoring and electronic door systems.Communications - Phone system energized or some phones with the system.Hazardous Ventilation - Exhaust ventilation for rooms that contain toxic chemical storage.Emergency Lighting - Lighting for exit walkways and exit signs throughout building.Examples of types of systems powered are:
Many of these style circuit breakers are equipped with an LED to indicate power. Often power is supplied to individually-designated circuit breakers. The next level of switchgear is used for industries that do not have mission critical power requirements. This is an example of the simplest switchgear application. In this simple application, the automatic transfer switch supplies power to the circuit breaker in the panel in the home when power is lost.
Residential emergency generator applications today use the circuit breaker panel as the switch gear. The knife switches advanced to enclosed circuit breakers to prevent shock. However, as current and voltage needs escalated, the open knife switch concept became a safety hazard. This consisted of knife switches mounted on panels constructed of marble or asbestos. The first switchgear used was in power station applications. To get more technical details on transfer switch technology, NEC Requirements, maintaining transfer switches and more ASCO has an extensive library of technical whitepapers worth checking out. Only the generator for the building with failed utility power would initiate.Īs an ASCO Reseller, Generator Source offers a wide variety of ATS products. With this style of installation, it is possible that one building on the site loses utility power and the remaining has power. When utility power is lost to the site, each individual building's ATS performs its duties and emergency power is brought online until power is restored. The sequence of automatic transfer switch events is basically the same as the single generator configuration. The installation configuration of the generators does not allow parallel operation even if the generator control panel has paralleling software installed. The figure to the right demonstrates an example. These sites often employ the use of multiple generators. Some sites have buildings that are located far enough apart to prevent paralleling operations during loss of power.
