Electrostatic Field,d orthogonal coordinate systems were discussed in detail. In a static electric field, the electric charges are always at rest and the electric field does not change with time, i.e., its magnitude is constant. The electric field due to time-invariant charges at rest is called the static electric fiel

,Poisson’s and Laplace’s Equations,on or electrostatic potential should be known to apply those laws. There are many practical problems where the charge distribution is not known for every place. There is some complex geometry in high voltage engineering equipment, namely insulators, bushing, surge arrestors, etc. In that case, it is

Time-Varying Fields,, the time-varying electric and magnetic fields are dependent on each other. In other words, a time-varying electric field is produced by a time-varying magnetic field and a time-varying magnetic field is produced by a time-varying electric field. The first concept was experimentally introduced by M

Transmission Lines,ion system with a low frequency. Coaxial cables, parallel-wire transmission lines, and microstrip lines are used for power transmission. Using high insulation cable reduces electromagnetic interference during power transmission. The parallel-wire transmission line is used for overhead transmission a
