Pole slipping of a synchronous machine occurs during
insufficient electromagnetic torque to hold the rotor in
synchronism with the stator magnetic flux It is caused
by an imbalance between the mechanical power and
electrical power of a synchronous machine. Pole slipping
either between generators and systems, or between two
sections of the systems, results in a flow of synchronizing
power, which reverses in direction twice every slip cycle.

Generator pole slip protection is a protection system used in synchronous generators to prevent damage caused by pole slip or loss of synchronization. It continuously monitors the angular position of the generator rotor and compares it with the reference angle. If a significant deviation is detected, the protection system activates to disconnect the generator from the power grid and shut down the unit to prevent further damage.

What is meant by pole slipping?
A pole slip occurs when a motor or generator cannot maintain synchronicity. This occurs because the field excitation is too low.
What are the functions of slip ring carbon brush external resistor in an alternalting EMF generator?
good question the use of slipring carbon brush is to give excitement to the generator , as the carbon brosh contact the rotor slip the rotaion and the speed of the generator increases we can say as an external force by anonrafee blueroz_27@yahoo.com
What affect does a leading power factor have on alternator generator excitation currents?
When a leading power factor load is applied, the voltage of the genset or genset bus rises, and the voltage regulation system reduces exciter power, reducing the strength of the magnetic field. If the field fails, the generator set may slip a pole, which results in potentially catastrophic alternator damage. pawan
Is slip ring a part attached to each end of the wire loop in an ac generator?
In a very simple, laboratory-type, a.c. generator -yes. In practical generators, the output (armature) windings are part of the stator, so do not rotate and, so, don't require slip rings.
When slip ring get negative charge in ac generator?
you apply dc voltage to slip rings in synchronous generators polarity will make no difference ( other than when it is first applied )
What is pole slip in generator?
the link: http://www.av8n.com/physics/power-grid.htm defines pole slip as: " if the load mismatch becomes extreme, one generator could slip 2pi of phase relative to the other. In the industry this is called pole slip".

What is the function of slip rings in ac generator?
They rotate the armature coil.
How can you generate a DC?
U sohuld replace the slip-ring which it is in the AC generator to a commutator. It is a split-ring. Then u can produce DC generator.
What is DC generator?
because DC generator generates generally generate DC power but as it has slip rings which convert it into ac output power

Does a generator produce direct current or alternating current?
A generator produces an alternating current, still it gives d.c. output because we use slip-rings at the terminals of actual output of generator.

Difference between induction motor and induction generator?
in case of induction motor the rotor speed is less than synchronous speed giving positive slip but in case of generator the rptor speed is greater than synchronous speed giving negative slip.......

In the generation of electricity commutator would be used on an alternating current generator and slip rings would be used on a direct current generator?
No. Just the opposite. An AC alternator uses slip rings, a DC generator uses a commutator. Most modern auto alternators are in fact AC alternators that rectify the AC output to DC using a diode bridge.
