A power distribution center (PDC) is electrical equipment designed to regulate the distribution of electrical power to various equipment, be that to machines in a factory or to various systems on an automotive vehicle. Typically, a switchgear supplies power to the PDC.
What is a distribution system in electricity?
Distribution systems in general
In general, the distribution system is the electrical system between the substation fed by the transmission system and the consumer end. It generally consists of feeders, distributors.
What is the main power distribution center of the ship?
The main switchboard is the main power distribution center of the ship. Thus the main bus bars are contained within the switchboard feeding various ship board auxiliaries. A ship may contain two or more generators connected to the main bus bar via the circuit breaker.
What is primary distribution system?
A primary distribution is an initial sale of securities on the secondary market, such as in the case of an IPO. … Unlike secondary distributions, primary distributions are a direct source of funds for the company issuing securities to raise capital.
What is service Main?
“Service Mains: A service main is generally a small cable which connects the distributor to the consumer’s terminals.
What is emergency switchboard distribution?
The emergency switchboard is the emergency power distribution center. The emergency switchboard distributes 450 volts and 120 volt power to auxiliaries which are vital under emergency conditions, essential lighting, safety and communication systems, and power necessary for dead ship starting. .
Where do cruise ships get electricity?
Cruise ship engine power is supplied through the transmission to the propeller shafts. These transmissions determine the revolutions of propellers. Modern ships use either diesel-electric engines or gas turbines as a source of power for propulsion, and for ship’s systems.
What is the difference between main switchboard and emergency switchboard?
Emergency switchboard is a switchboard which in the event of failure of the main electrical power supply system is directly supplied by the emergency source of electrical power or the transitional source of emergency power and is intended to distribute electrical energy to the emergency services.
What is secondary electrical distribution?
Secondary distribution systems. A low-voltage network or secondary network is a part of electric power distribution which carries electric energy from distribution transformers to electricity meters of end customers.
What is primary line in electricity?
Primary lines, or primaries, are higher-voltage lines located at the top of utility poles, above transformers. Primary wires are typically Copper, Aluminum, and Aluminum with Steel Reinforced conductors. … Although the voltage is lower, these lines can still deliver a severe electric shock if contacted.
What is primary distribution of overhead?
Primary distribution of overheads refers to allocation and apportionment of overhead expenses among production and service departments of an organization.
What is overhead service in electrical?
Overhead service feeds include power poles that string feeder wires from the utility company’s pole to the power pole by your home. From there, the feeder cables run overhead and connect to a service mast that runs through your roof or is mounted to the side of your home.
What is difference between feeder and distributor?
Distributor is a line from which tapping are taken along its length for providing supply to the consumer. Feeder: A feeder is a conductor which connects the sub-station or local generating station to the areawhere the power is distributed.
What is the feeder in electrical?
In electrical engineering, a feeder line is a type of transmission line. In addition Feeders are the power lines through which electricity is transmitted in power systems. Feeder transmits power from Generating station or substation to the distribution points.
