Electrical Engineering

how, in simple terms, would you describe a ring main (Specifically medium voltage)

It is 1 million watts. Watts are a measure of the rate of energy transfer. Mega is one of the metric system prefixes meaning million. For more information see the link below. It can be applied to quantities such as watts.
A megawatt is one million watts or one thousand kilowatts.
The watt is the unit that is used for measuring electrical power, 1000 watts = 1 kilowatt and 1000,000 = 1 megawatt.

The pulses differ because the two pulses are in opposite directions.

basically there will not be any difference between them.

the capacity of equipment will be more such as the CB rating will be more

Hi pass says it passes higher frequency signals and blocks lower pass signals. This isn't typically a hard cutoff point but the lower frequency signals get attenuated over a frequency range. The R stands for resistance and C for capacitance such that these components are used to create the pass band for the circuit.

1. D.C Shunt Motors:It is a constant speed motor.Where the speed is required to remain almost constant from noload to full load.Where the load has to be driven at a number of speeds and any one of which is nearly constant.

Industrial use:

Lathes

Drills

Boring mills

Shapers

Spinning and Weaving machines.

2. D.CSeries motor: It is a variable speed motor.The speed is low at high torque.At light or no load ,the motor speed attains dangerously high speed.The motor has a high starting torque.(elevators,electric traction)

Industrial Uses:

Electric traction

Cranes

Elevators

Air compressor

Vacuum cleaner

Hair drier

Sewing machine

3. D.C Compound motor: Differential compound motors are rarely used because of its poor torque characteristics.

Industrial uses:

PressesShears

Reciprocating machine.

A step-up transformer produces a voltage across its secondary winding which is higher than its primary winding. The secondary winding is connected to the load, while the primary winding is connected to the supply.

it consist of a permanent magnet as stator and a low resistance solid metalic cylinder as rotor, which drives the pointer and scale arrangement. the rotor is also connected to shaft which has a provition to get contact with the rotating machines,whose rpm has to be measured. when it get contact to a rotating machine the shaft rotates which eventually rotates the metalic cylinder in strong magnetic field , its known that when a low resistant metal rotated in a strong magnetic field eddy current gets induced in the low resistance metal opposing the cause of action which held the pointer in equilibrium position showing some reading which will be caliberated for the corresponding speeds hence it shows the correct rpm in which the machine rotates

A reflector is a, usually large, sheet of reflective material used to reflect light into shadows of a subject. It is usually used where there is strong lighting from one side to even up the light in an image.

The value of resistance of shunt field winding beyond which the shunt generator fails to build up its voltage is known as " critical resistance

at a given speed it is the maximum field resistance with which the shunt generator excite.

There are two important different parameters as far as the disconnection/connection of Electrical utilities is concerned.
- Breaking capacity.
- Making Capacity.
In simple way the Load Break Switch used to cut off healthy circuits or to break / disconnect the load. As a precaution, normally the LBS / Isolator are to be switched on under no load, the connected load to be utilized after switching on the Isolator. This why it has no making capacity. Circuit Breakers are intended to operate under unnormal conditions in order to clear the fault & to isolate the defective circuits protecting its associated electrical equipment, therefore breaking and making capacities are considered as the most important criteria as far Circuit breaker are concerned.

A current greater than which a circuit is designed to carry , may melt wires or damage elements of the circuit.This is known as overloading of current.

I HAVE A SMALL ELECTRIC CLOCK MOTOR THAT I NEED TO REVERSE. WHAT IS THE CIRCUIT I NEED TO REVERSE IT?

a pipe fabricator would be a pipefitter that fabricates pipe in a shop or in the field.he/she does this with a welder and a helper.a number of power tools.he takes a set of iso drawings and cuts pipe to length and makes the fittings until he has fabricated what the drawing he has in his hand calls for.they send it to the place it has to be installed at and install it.most times.alterations are made in the field.

To use your left hand to determine the direction of the voltage developed in a moving conductor in a stationary magnetic field, you must point your forefinger in the direction of the lines of force.

which obey ohms law

ANSWER: Not all potentiometers are linear some are made to follow a logarithm function some follows an exponential function. A linear potentiometer will have a linear curve.

Materials that obey Ohm's Law are called 'linear' or 'ohmic'; those that don't are called 'non-ohmic' or 'non-linear'.

A fixed capacitor used in electronic equipment.

The voltage at which the adc converts the signal.... it can also be called a limit of an ADC.

Usually HV is 33KV and 66KV, EHV is 132KV, 220KV and 400KV and UHV is 800KV and 1200KV

I think you're talking about a grounding connector that allows multiple connections to be made to it, thus looking like a 'Star' when viewed from above.

This would be opposed to a single-connection 'jack' where only one connection is made to the 'jack', or lug.

It means the neutral is not grounded.

Well the same reason fire doesn't stay at the same temp. is always changing
