What are the three main sources of heat in a transformer?
Expert Solution & Answer
To determine
The three main sources of heat in a transformer.
Explanation of Solution
The transformer is an electrical device that is used to transfer energy in the form of electricity from one circuit to another circuit. The electric energy transformation takes place by the process of electromagnetic induction. The transformer is used to increase or decrease the voltage as per the requirements of the application.
There are three main sources of heat generation in the transformer are listed as below.
- 1) Electric winding of transformer.
- 2) Core material of transformer
- 3) Losses in transformer such as, flux leakage, eddy currents, and hysteresis.

Each of the two chain sprockets delivers 2.0 hp to the side to drive mixer blades in a chemical reactor vessel. The bevel gear has a diametral pitch of 5, a pitch diameter of 9.000 in, a face width of 1.31 in, and a pressure angle of 20°. Use SAE 4140 OQT 1000 steel for the shaft. See Chapter 10 for the methods for computing the forces on the bevel gear.

The double-reduction, helical gear reducer shown in Figure P12-35 transmits 5.0 hp. Shaft 1 is the input, rotating at 1800 rpm and receiving power directly from an electric motor through a flexible coupling. Shaft 2 rotates at 900 rpm. Shaft 3 is the output, rotating at 300 rpm. A chain sprocket is mounted on the output shaft as shown and delivers the power upward. The data for the gears are given in Table 12-5. Each gear has a 1412° normal pressure angle and a 45° helix angle. The combinations of left- and right-hand helixes are arranged so that the axial forces oppose each other on shaft 2 as shown.
