What benefit does electric power have on factories?
To see this simply go to any old factory that was around before electric motors. You will see the reminants of an intricate power delivery system to drive rotating equipment. Long axles ran across the roof of the building, with power take off pullies every few feet. Each machine was powered from one of these pullies, so each machine had a belt running to it from the cieling. To stop and start an individual machine a clutch was needed, as stopping the steam engine or whatever else powered the whole plant was not an option. All the rotating equipment posed a huge safety hazard, and I'm willing to bet arms were lost to those belts. If a belt came off the pulley the axle had to be stopped to (safely) get that machine on-line again. Electricity de-centralized this power system. Instead of one big engine powering everything, small motors powered individual tools. The need for all the belts and axles was eliminated. Machines could be run and repaired independently. Machines could be stopped and started with a cheap switch, not an expensive clutch. Also, electric lighting was safer and brighter than gas. IIRC fires were serious problems in plants that produced lint or dust because of the explosion hazard.
What is auto transformer stater?
I think you are confusing your terms. The term 'stator' (not 'stater') is used to describe the stationary part of a rotating machine (motor, generator), as opposed to the term 'rotor' which describes the rotating part. No part of an autotransformer is normally described as a 'stator'. An autotransformer has a laminated silicon-steel 'core', around which are placed 'windings'.
Why Disconnect switch should be placed before current transformer cabinet?
Usually disconnects are placed around any equipment that you may have to do maintenance on in the future and don't want to have to take larger outages than necessary. If the current transformer is on a substation bus, and you don't want to take an outage to that bus, but would like to take a look at the CT's, you should put disconnects around it to allow such maintenance activities.
Why don't we have rocket powered aircrafts carrying passengers across the continents so it would limit the travel time to an hour no matter where you travel in the world?
All in good time, powered flight has only been around for just over 100 years. Right now the cost and technology isn't in place.
How does an auxiliary winding provide a starting torque for single-phase induction motors?
Single- and three-phase motors work on the sameprinciple. The field windings create a rotating field which cuts the rotor bars of the rotor, inducing voltages into them, and the field produced by the resulting currents react with the rotating field causing the rotor to spin. If you like, the rotating field 'drags' the rotor around with it.In the case of a three-phase motor, the three out-of-phase phase currents create a naturally-rotating field. However, in the case of a single-phase motor, we must simulate this. This is done by having two, separate, field windings. One is fed directly from the supply, and the other is also fed from the supply via a capacitor. This results in two field currents which are displaced from each other by around 90 electrical degrees, when then create the rotating field necessary for the motor to start and run. You could say that a single-phase motor is equivalent to a 'two-phase' motor. The field winding supplied via a capacitor is known as the 'start winding' or the 'auxiliary winding'.
Should gloves be worn around powered rotating equipment?
No
You should NOT wear gloves around powered rotating equipment.?
true
What color all around light should a non powered canoe have?
That is a white light.
How do four seasons occur?
by the earth rotating around the sun while the moon is rotating around the earth.
Is the sun constantly rotating and revolving around the earth?
no, it's the Earth that is constantly rotating around the Sun
Why it seem to see the sun rotating around the Earth?
because earth is rotating around itself while revolving around the sun
What revolves around the sun while rotating its side?
Earth revolves around the sun while rotating on its sides
What should a non powered kayak display in reduced visibility?
All around white light
What colored around light should a non powered canoe or kayak display?
A white light.
Is it possible to heve three suns in one universe?
No. If you have three suns rotating around each other, that would mean that an object would have to be rotating around two other objects that are rotating around the other two objects, which is rotating around the two original objects. It just can't work
