A Servo is a small device that has an output shaft. This
shaft can be positioned to specific angular positions by
sending the servo a coded signal. As long as the coded
signal exists on the input line, the servo will maintain the
angular position of the shaft. As the coded signal changes,
the angular position of the shaft changes. In practice,
servos are used in radio controlled airplanes to position
control surfaces like the elevators and rudders. They are
also used in radio controlled cars, puppets, and of course,
BASICALLY IT WORKS ON A ELECTRO MAGNETIC INDUCTION
servomechanism, or servo is an automatic device that uses
error-sensing negative feedback to correct the performance
of a mechanism. The term correctly applies only to systems
where the feedback or error-correction signals help control
mechanical position or other parameters. For example, an
automotive power window control is not a servomechanism, as
there is no automatic feedback that controls position—the
operator does this by observation. By contrast the car's
cruise control uses closed loop feedback, which classifies
it as a servomechanism.
How to find Cable size?
Caterpillar generator produce (Two generators) 127*2=254 amp
at 11 kv .
What would be the cable size (XLPE) to supply 256 amp at 11
kv? Air or surrounding Temperature is 32 degree C. Cable
will go under ground at 2.5 feet depth. Group Rating Factors
is 3 cables. Clearance between cables is 7 cm. Soil
Temperature (Ambient) 28o C Soil Thermal Resistivity is 1.2
I would like to use 3 separate single core instead of using
3 core cable.
Some says I should use three separate single core 120RM cables.
Some says 70RM .some says 95.
I m totally confused.
Is there ant specific rule to determine cable size?
What would be the LT cable size to flow 500 Amp current?

Anyone please send me the answer to my e mail address,
i will be very glad.
