A terminal sub-station is one in which the line supplying to the substation terminates or ends. ... In the latter case, a tapping is taken from the main line to supply to the sub-station. Fig shows the schematic connections of a terminal sub-station. It is clear that incoming 11 kV main line terminates at the sub-station.

The typical RJ-11 connector has six terminals. Usually, only the middle four pins are used. The POTS (Plain Old Telephone Service) residential telephone wiring generally contains two pairs of wires - designed for two separate telephone lines.

A switching station is a substation without transformers and operating only at a single voltage level. Switching stations are sometimes used as collector and distribution stations. Sometimes they are used for switching the current to back-up lines or for parallelizing circuits in case of failure.

Terminal voltage is the potential difference across the terminals of a load when the circuit is switched on. E.m.f. is the maximum potential difference that can be delivered by a cell or a generator when no current flows through it.

Transmission lines are for large distances, their voltage is higher, and they can transport more electricity. You can see them on the side of the freeway for example. Distribution lines are for short distances, their voltage is lower, and they transport electricity locally. You can see them on the side of the street.

Grey-colored cables typically represent standard ethernet connections, while green cables represent crossover ethernet connections. Yellow cables are used to signify POE (power over ethernet), while blue cables are used for terminal server connections.

the "ground" terminal is always the zero-volt reference point. If you have a mixed signal circuit, you may find that you have a ground terminal, along with a positive voltage, and a negative voltage. ... If you're working with a single power supply, then your negative voltage terminal is probably the same as "ground".

Class 3 wiring is functionally similar to Class 2 wiring, but with higher voltage and power limitations. Major differences in the installation of Class 2 wiring are that conductor sizes 18 and 16 AWG are permitted and splices, such as with wire nuts, are permitted outside of conventional enclosures.

It is just the potential difference across a cell in a circuit. ... If a current is flowing then the terminal potential difference of cell will be lower than its EMF, as some loss of energy takes place inside the cell due to its internal resistance.

As nouns the difference between device and terminal is that device is any piece of equipment made for a particular purpose, especially a mechanical or electrical one while terminal is a building in an airport where passengers transfer from ground transportation to the facilities that allow them to board airplanes.

The difference between each is in the end point of the wire. Male ends have a pin protruding and can plug into things, while female ends do not and are used to plug things into. Male-to-male jumper wires are the most common and what you likely will use most often.

A fixed PLC has input and output ports in one fixed enclosure. A modular PLC has each discrete pr fixed input and output ports place in different racks. ... Name the major components of a PLC power supply.

A one way light switch has two terminals which is a common marked as COM or C. The common is for the live wire that supplies the input voltage to the switch. The other terminal is marked as L1 and is the output to the light fixture.

In a normal switch, the two terminals are either connected (as shown) or disconnected. When they are connected, the switch is "on." In a three-way switch, the top terminal connects to one or the other of the bottom two terminals. ... Special switches known as three-way switches.

Gantt Chart vs Network Diagram. ... The main differences are: Gantt charts is a Stacked Bar Chart to represent Project Schedule in Graphical Representation. And the Networks diagram is Flow Chart representation of sequential workflow of the Project Tasks.

D-sub was a standard for computer connectors while DVI is a standard connector for video displays. 2. DVI is fairly new while D-sub is a very old and almost obsolete standard. 3. DVI is used purely for displays while D-sub was used for a wide variety of applications.
