CT Knee point voltage

all the power system protection contolled by two instrument transformers.1.CT 2.VT
CT itself has some saturation. after the sturation region CT will not sense the FAULT.
so we have to design our CT upto max level fault in order to protect the power system equipments. assume a 11KV switchboard has shortcircuit current 30KA.
so during this time defenetly there is voltage in order to drive this SC current.
like 660V something. so if we design our CT around 900V or more then the 660V total
power system will be protected from the fault. this voltage called as VKP.Knee point voltage. if you want i can give detail how design and calculate.

Indution motor is used in fan and capacitor is attached, to rotate in anti clockwise direction.

In this way, the shadow of the fan rotating at the floor is clockwise.

Ceiling fans can be set up to rotate either way, many of them have a switch that will change the direction. Others can be wired to rotate either way. Typically they are designed to push air rather than pull it.

Due to purpose of usage, we have designed this fan for cooling or spreading fresh Air, so direction of pushed air it's our need.

I'm pleased to read previous answers which were about how to operate the Fan.

mostly, 1 phase induction motors are employed in fan's if you can change the direction of 1 phase induction motor wan interchange the windings of main winding & auxiliary winding supply.

In ceiling fan the stator of the single phase motor is rotating ,to which the blades are attached,our purpose is to get air downwards ,for this reason we have to make the phase and neutral connections

If the connection of 1 phase and capacitor is changed the rotation becomes clockwise, but due to special shape of blade of fan to through air downward , rotation must be anticlockwise. If u change the shape of fan nd connection both properly, it works

flux is produce in clockwise direction and eddy currents makes fan to rotate in anticlockwise direction..........

When fan stops suddenly and starts running in clockwise what is it due to?
