Capacitance of electric cable

  1. Jan 1, 2015 #1
    Anybody please help to tell me if there's a book or journal that clearly describe the definition and differences ( best if it comes with illustration or diagram) between these engineering terms:
    (1)partial capacitance
    (2)mutual capacitance
    (3)self capacitance
    (4)earth capacitance
    Thank you!

    "Cable" + "capacitance" yields a half million hits. Are you interested in power cables? Signal transmission/distribution? Instrumentation cables?

    I found Time Domain Reflectometery very valuable in my work as reactor plant electrician.

    What is "partial capacitance"? I haven't heard that term before...

    doesn't really make sense to me either, Berkeman
    capacitance either exists or it doesn't and it has a value, small or large

    Suppose a system of any number of finite size, galvanically separated conductors placed at some distances from each other and at some distances from "infinite" or very large conductor. That very large conductor can be earth (earth's equipotential surface), and this situation for 3 conductors and earth is illustrated in the following pic:

    Anylisis show that in electrostatic case there are 6 uniquelly defined capacities in linear dielectric medium. 3 mutual capacities between conductors (Cm) and 3 capacities of conductors to earth (Ce). To my knowledge, each one of these 6 capacities is referred to as a "partial capacity".
