Well, the slip rings are used in AC ( Crane duty Motors )
to add extrenal resistance to increse starting torque.
DC motors are with different construction. A commutator is
used to supply DC to armature.

How do i perform grounding of star point of Genset (400V) for making connection with step up transformer of DELTA-DELTA (400V to 20KV) ? while Genset itself has its own neutral and grounding bus bar inside genset breaker box whereas we have another neutral and grounding busbar in synchronizing panel next to genset at maximum distance of 6meter, would someone pls advice if we can only perform neutral grounding in synchronizing panel or should we ground neutral on both places inside genset breaker box and synchronizing panel.
what are the reasons of CT circuit faulty in busbar protection scheme?
which are the criterias needed to select the kind of neutral earthing(solid earthing,resistance earthing,etc.) at various voltage levels in electrical distribution?

Hi,I am working in abroad for more than 3 years in a company operating with 11kv and 6.4 MW power. I need c licence in India,can I? some other says only i can get if i work for 2 years in india only! anybody kindly clarify by doubt.Thanks
A ray hit a smooth regular surface at an angle of 20 from the normal. Calculate : 1. The angle btw the incident and reflection ray. 2. The angle of deviation.
which IS or IEC is used for earthing,breakdown voltage of transformer oil, hv/pd testing and all type of electrical testing
A 500 V shunt motor runs at its normal speed of 250rpm when the armature current is 200A. The resistance of the armature is 0.12 Ω. Calculate the speed when a resistance is inserted in the field reducing the shunt field to 80% of normal value and the armature current is 100A.
