Paralleling Switchgear
Paralleling switchgear is key to maintain synchronism in your power system.
What is Switchgear?
Electrical switchgear refers to a centralized collection of circuit breakers, fuses and switches (circuit protection devices) that function to protect, control and isolate electrical equipment. The circuit protection devices are mounted in metal structures. A collection of one or more of these structures is called a switchgear line-up or assembly.
Switchgear is commonly found throughout electric utility transmission and distribution systems as well as in medium to large sized commercial or industrial facilities. Standards for electrical switchgear are defined by IEEE in North America and by IEC in Europe and other parts of the world.
Low Voltage Paralleling Switchgear
APT Low Voltage (208V, 480, 600V+) metal enclosed switchgear can be built for indoor and outdoor generator paralleling applications. We also offer a Paralleling Generator Distribution Switchboard (GenProtect-P). Also available are a variety of low voltage switchboards, panelboards, and tap boxes to meet any of your power needs.
Medium Voltage Paralleling Switchgear
APT Medium Voltage (5kV – 15kV) metal enclosed switchgear can be built for indoor and outdoor generator paralleling applications. Our Medium Voltage Paralleling Switchgear is available in both full and compact sizes, and features vacuum circuit breakers.
Switchgear vs Switchboard
The term “switchgear” is sometimes used synonymously with switchboard. However, the difference is the way the equipment is manufactured.
Switchgear features compartmentalized construction to limit arcing risks from inadvertent contact with energized equipment. In Switchboards, it is not required to compartmentalize, enabling greater configurability and more equipment to be installed in each frame.
