12.1 Parallel and Serial Equivalent Circuit Diagrams
The dielectric losses in insulation can be presented in parallel and serial
diagrams. The real situation is much more complicated and always is a mixture
of an assortment of both diagram types. A parallel can be recalculated into a
serial one and vice versa by using the following formulas.
