Its related to short circuit current because of that when we
design any plant and there electrical system. design
engg.(first calculate the total load)calculate the max SC
current according to that equipment will be select. Its
called the fault level:
it divided into 2 (Major):
low fault level (for normal equipment)
high fault level (for critical equipment)
as per total load of plant or capacity.

Suppose a 3 phase, 2 pole, 440V induction motor is driving a flywheel of 600mm diameter, 150kg mass. By using v-belt and pulley, the speed is increased to 4500 RPM. What will be the effect on motor current?
in cvt,there are two windings,1a,1n and 2a,2n.in my one project i use only one winding i.e.1a,1n. the other winding is not in use, so i connect it in open delta and want to close it by ibsertibg thermal resistor. the output of cvt is 132kv/115/sqrt3. plesae tell me exact value of resistor, so i may close it to avoid the resonance phenomenin. send me answer on this email adress please. aetcon-po@aetcon.com
