The insulators of overhead power lines play a crucial role in maintaining the reliability of transmission and distribution networks. Because they are exposed to harsh and dynamic environmental conditions, it is essential to investigate the impact of environmental parameters such as pollution, inclined angle with the cross arm, and temperature on the dielectric performance of the insulators of overhead lines. Conventionally, the effect of such parameters can be investigated through experimental measurements of the insulator flashover voltage.

- To optimize the performance of a Hybrid Excitation Synchronous Machine (HESM) in hybrid electric vehicles (HEVs), key indicators like back-EMF, inductance, and unbalanced magnetic force (UMF) should be calculated using analytical methods.
- The study calculates back-EMF considering various winding configurations and examines how different magnetization patterns (radial, parallel, Halbach) affect the waveform.
- To reduce UMFs, the design of stator windings and permanent magnets is modified for symmetry; other factors, such as temperature impact on magnet strength and optimizing the ratio of permanent magnet flux to rotor flux, are also considered to enhance average torque.
