basically torque of dc motor mainly depends on armature
current and flux.for a dc shunt motor ,this flux is nearly
a constant but for dc series motor this flux is mainly
dependent on armature current.so torque of dc series motor
is now dependent on square of armature current. hence it
has a very high starting torque.

When we have earthing mesh or underground earthing network in industrial plants, weather we have NT-S or NT-C-S kind of earthing system, so eventually weather we must use 4 or 5 wire in 400 volt level (For example 3×150+70 mm2 or 5×150 mm2) in this connection I would like to know exactly the paragraph of IEC or IEEE number
