Saturation in Current Transformers

The current transformers for measuring service have a core made of high permeability magnetic material. This means that they have little excitation current, small losses and low reluctance. They work under conditions of low magnetic induction (about 0.1 tesla). They enter into saturation as soon as the magnetic induction grows to (0.4 to 0.5) tesla. […]

Winding Temperature Rise

Heat from the losses inside an enclosed electric motor is properly dissipated into ambient air through the outer surface of the housing. In closed motors, this dissipation is usually assisted by the fan designed on the motor shaft itself. Favorable dissipation varies according to the efficiency of the ventilation system of the total dissipation area […]

Transformers Bearings
