What is the function of busbar?
Busbars, also known as busbar trunking systems, distribute electricity with greater ease and flexibility than some other more permanent forms of installation and distribution. Sometimes spelled bus bar or buss bar, they are often metallic strips of copper, brass, or aluminum that both ground and conduct electricity.
How many types of busbar are there?
The types are: 1. Single Bus-Bar Arrangement 2. Single Bus-Bar Arrangement with Bus Sectionalization 3. Main and Transfer Bus Arrangement 4.
What is bus bar connections?
They are typically a strip, a bar or sometimes a tube made of copper, brass or aluminum optimized for current requirements and performance specifications. Busbar connectors are parts used to connect busbar systems to the power module or other parts of the assembly.
Why is it called a bus bar?
The term busbar, often spelt ‘bus bar’ or ‘buss bar’, is derived from the Latin word ‘omnibus’. It translates into English as “for all” which indicates that busbars carry all of the currents in a particular system.
What is main bus and transfer bus?
The main and transfer bus configuration connects all circuits between the main bus and a transfer bus (sometimes referred to as an inspection bus). Some arrangements include a bus tie breaker and others simply utilize switches for the tie between the two buses.
What is necessary of bus bar?
The main purpose of busbars is to conduct a substantial current of electricity and are typically housed inside switchgear, panel boards or busways. Rather than branching the main supply at one location, busbars allow new circuits to branch off anywhere along the route of the busway.
Where are busbars found?
Busbars are usually housed inside switchgear, panel boards and busway enclosures for local high current power distribution. They are also used to connect high voltage equipment at electrical switchyards and low voltage equipment in battery banks.
What is bus bar voltage?
At extra high voltages (more than 300 kV) in outdoor buses, corona discharge around the connections becomes a source of radio-frequency interference and power loss, so special connection fittings designed for these voltages are used. 110 kV busbars in electrical substations.
What is bus PT and line PT?
Line pt means to measure incoming line voltage. Thebus pt means measure. The bus needs to be protected under the bus’s voltage. Protection for motor feeders.
Why transfer bus is used?
However, the transfer bus is used to improve the maintenance process by moving the line of the circuit breaker to be maintained to the transfer bus. Some systems are operated with the transfer bus normally de-energized.
