what is the difference between inrush curent and jurk load...

The inrush current is that value of current used to
overcome the inertia presented by the magnetic dipoles to
the impinging flux . The dipole resists the change in the
turning moment produced by the mag. field ( when machine is
started from rest state).
The jerk current is that value of current that is
drawn in excess of the already supplied current while the
machine is still in operation.
The jerk current is not required to oppose the moment
offered by the magnetic dipole , whereas the inrush current
is used to induce magnetism in a metal and hence overcomes
the dipole moment .
This is the striking diff. between the inrush current
and the jerk current

what is the difference between inrush curent and jurk load...

In case of AC Motor Inrush current is current drawn by
motor while at start.This inrush current is very high (
almost 5 -6 times full load current.) The reason is,at
start the back emf offerred is zero.This back emf is
developed as the rotor gains speed.Hence at start Current
drawn by motor is equal to Voltage divided by impedance of
stator winding( winding impedance is very low,hence
starting current is high.) Once the rotor gains speed
current drawn by motor is equal to Voltage- Back emf/
impedance.As back emf is developed now the motor draws less
current.

to jurk load motor draws high current in order to maintain
speed ( near synchronous speed)

Dear Sirs, I am a technical persons.In one of our Electrical Sub- Station, We have installed three numbers of 1250KVA ,11KV/0.415KV Transformer to feed the Factory load. We have found some abnormality. In one of our Transformers the leakeage current from transformer body to earth through earth continuity wire is almost 86 Amp but in other transformer it is (5-10)Amp. where the load current on three phase and neutral are respectively 1360Amp,1400Amp,1370 Amp & 176Amp. So please any technical person help me about the reasons of this situation and how I can rectify the fault. Moreover,I have measured the earth resistance of the Earth continuity wire which is less than 1 Ohm. Thanks Tapas Barua

a power supply to be constructed from voltage cells is required to provide Max. 20A Current with a terminal voltage of 6v.Several voltage cells are available each of which has terminal voltage of 1.5V & each of which can supply a max current of 5A .the no of cells required will be ??

what is difference b/w CFL and Ordinary lamps? which one is useful for power saving?

What is primary and backup protection?

Our Alternator nameplate specifies a power factor of 0.8. When the Alternator is on light load, the bus bar voltage rises to 11240 volts, whereas the standard value is 10500 volts. Is it ok to increase the power factor to 0.85 or 0.9. I am afraid because the power factor on the name plate is only 0.8 ?
