iii) A shunt motor runs at 70 rad/sec from a 460V
supply and takes in an armature current of 100A. Resistors
of 2.52 ohms and 1.64 ohms are connected in series with the
armature and in parallel with the armature respectively.
The field excitation remains direct from the 460V supply
but the generated torque is halved. Determine the new
running speed. Neglect brush voltage drop. The armature
resistance is 0.4 ohms.

We have a 33/11kv switchyard having 12.5 MVA power transformer. We export & import power through this transformer. When we export power, the PF will be depend on GRID PF & when we import power the PF will be depend on our load PF. but the problem is that,when neither we export nor import but our 33KV vCB is in close position,our meter read the power factor 0.14 to 0.25 at that moment. So how can be we improve the power factor at that moment.
