The Magnetic neutral axis or plane (M.N.A)coincides with the
geometrical neutral axis or plane (G.N.A).M.N.A may be
defined as the axis along which no e.m.f is produced in the
armature conductors or the axis which is perpendicular to the
flux passing through armature.

Answer / dhanunjayareddy

the axis along which the resultant induced emf is zero across the conductor which is rotating

In the solution of load flow eqation, Newton raphson method is superior to the gauss siedal method because (a)the time taken to perform one iteration in the NR method is less when compared to GS method (b)the number of iterations required in the NR method is more compared to that in the GS method (c)the number of iterations required is dependant on the size of the system in the NR method (d)convergence characteristics of the NR mehod are not affected by the selection of the slack bus

1. for eg, capacitor is used for many purposes(it act as filter, oscillator, bypass capacitor, memory storage etc...) 2. Please tell me some example circuits for different uses of capacitor( whenever and whereever and however we used capacitor as a filter, oscillator tuning etc..) 3. similarly for inductor and resistors(it act as what?) and when and how we want to act as like that?, and how we can used these components depends upon our requirments with example circuits and explanation? design to act as these components depends

Sir,In our company there are 3 caterpillar make(capacity:(1) 3.3KV,2.5MW(2)3.3KV,2.5MW & (3)3.3KV,1.9MW) & 1 deutz make (capacity:11KV,3.8MW)gas engines utilised,all are running in paralell. There are three transformer utilised,(1) 6.25MVA,3.3KV/22KV,Impedence voltage:6.7% used for two generator,both are 2.5MW(2)5.5MVA,3.3KV/22KV,Impedence voltage:7.2% used for one generator of 2.5MW & (3) 5.5MVA,11KV/22KV,Impedence voltage:7.8% used for one generator of 2.5MW.all generator breakers capacity of 1250Amps. Sir,I want the details of fault level calculation of generator,transformer individually & for whole system. If you require any information from me.feel free for contact me sir.pl.send the answer of my question as the earliest as possible.
