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...

Thanks for the link, but for me that brief description doesn't help much. I guess I'll try a little Google searching...

Abstract

In the analysis of electrostatic-field problems for multiconductor systems withn+ 1 conducting bodies immersed in dielectric media, the capacitive coupling effects among conductors can be described by means of a partial-capacitance scheme consisting of a network ofn(n+ 1)/2 capacitors, each one linking each conductor pair. From a physical viewpoint, each capacitor is usually associated with the existence of lines of force of the displacement field vectorDfrom one conductor to another. In this paper, we show that such a physical interpretation not only cannot be taken literally, but also, above all, can be a misleading one. If care is not taken, computation procedures based onD-field integration may lead to a wrong evaluation of the partial-capacitance scheme. For illustration purposes, a very simple example of a symmetric three-conductor system with odd-mode excitation is analyzed. © 2005 Wiley Periodicals, Inc.

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

Anylisis show that in electrostatic case there are 6 uniquelly defined capacities in linear dielectric medium. 3 mutual capacities between conductors (C
