Here is a typical AC circuit connected to an impedance load: (Please see below Structure)
Note the components. There is a "hot" conductor (120 V.), a neutral wire (0 V.) and a ground
wire. Along with the load, these are the essential components of an AC circuit. Also indicated
in the diagram are reactive currents that are typically present in the power circuitry with every
non-linear load application. Reactive current is basically capacitively discharged energy that
is keyed to a modulating AC source -- a "backwash" of non-active power. This is wasted
energy that is not being actively processed by the load. The important thing to understand
here is that reactive currents are natural phenomena. Unfortunately, the thrust of modern
power quality engineering has been to methodically "undo" what nature has done without
examining structure which is at the root of the problem.
Notice that reactive currents have invaded our (assumed) zero reference potential
(the ground.) This is called the common mode noise circuit. Because there was no
voltage present on the neutral, only active current, there is also reactive current present.
And, as reactive current from the load is applied across the source transformer's
impedance, reactive voltage is also quantified. In tandem, reactive current times
reactive voltage equals reactive power or "KVAR" (kilovolt-amperes reactive.) There is
how a reactive voltage potential presents itself in the grounding system of an AC circuit
-- via the neutral-to-ground connection at the AC mains. Here we are relying heavily on
the power supply's transformer for common mode noise rejection. This is essentially the
boundary where modern methods of noise suppression end.
Well, if all of the above seems confusing, don't worry about it. The important thing
to understand is that ground wires are dirty because non-linear loads create a condition
where zero (ground) is not truly zero. But as originally stated, these are the
consequences of a chosen architecture.
