General Knowledge Flashcards
What is the speed of a Static Transfer Switches?
Load transfer (typically 1/4 of a cycle), which ensures uninterrupted operation of sensitive electronic equipment.
A Static Power transfer Switch consists of three basic parts:
- A Breaker or a bus assembly
- Control System and metering system
- Silicon Controlled rectifiers – of which the internal structure is made up of
Co-location centers
A type of data center where equipment, space, and bandwidth are available for rental to retail customers. They are sometimes also referred to as “carrier hotels.” Colocation facilities provide space, power, cooling, and physical security for the server, storage, and networking equipment of other firms—and connect them to a variety of telecommunications and network service providers—with a minimum of cost and complexity.
What is a Network Switch?
To understand basic networking, you first need to answer the question, “What is a network switch?”
Most business networks today use switches to connect computers, printers and servers within a building or campus. A switch serves as a controller, enabling networked devices to talk to each other efficiently. Through information sharing and resource allocation, switches save businesses money and increase employee productivity.
What is a Network Switch?: Unmanaged Switches
An unmanaged switch works right out of the box. It’s not designed to be configured, so you don’t have to worry about installing or setting it up correctly. Unmanaged switches have less network capacity than managed switches. You’ll usually find unmanaged switches in home networking equipment.
What is a Network Switch: Managed Switches
A managed network switch is configurable, offering greater flexibility and capacity than an unmanaged switch. You can monitor and adjust a managed switch locally or remotely, to give you greater network control.
What is a Network Switch versus a Router?
Switches create a network. Routers connect networks. A router links computers to the Internet, so users can share the connection. A router acts as a dispatcher, choosing the best path for information to travel so it’s received quickly.
What is a Network Switch to My Business?
Switches and routers are the building blocks for all business communications, from data to voice and video to wireless access. They can improve profitability by enabling your company to increase productivity, trim business expenses, and improve security and customer service.
Closed transition transfer (CTTS) – what is it?
Closed Transition Transfer is simply another way to approach switching between two power sources. A traditional Automatic Transfer Switch (ATS) uses the
open transition principle also called breakbefore-make
transfer. A Closed Transition Transfer Switch (CTTS) simply takes advantage of the latest technological advances to avoid the momentary interruption during some of the transfers. The switch logic determines if
both source voltages and frequencies, and the phase relationship between the sources, are within acceptable limits. If all conditions are correct, the switch contacts
are allowed to make an overlap (makebefore-break)
transfer. This avoids the momentary interruption or the load that occurs with traditional break-before- make
transfer switches.
