1. the filter capacitors that are used in rectifier portion
of the VFD helps in boosting the power factor of the
substation.
2. in a motor electrical energy is converted into
mechanical energy. ie.
electrical power = rt3VICOSINE ANGLE
mechanical power = 2*3.14*N*T
By using VFD variable TORQUE and variable SPEED can be
achieved.so by reducing the mechanical power electrical
power will also be reduced in the same ratio.

There are different classes of protections in power plants.class a,b,c are clear..is there any class d and e r there..and elaborate class b protection.
When we have earthing mesh or underground earthing network in industrial plants, weather we have NT-S or NT-C-S kind of earthing system, so eventually weather we must use 4 or 5 wire in 400 volt level (For example 3×150+70 mm2 or 5×150 mm2) in this connection I would like to know exactly the paragraph of IEC or IEEE number
what is the meaning of osr in transformer.
