Neutral to Earth Volt issue

crutschow said:

Earth to neutral voltage can be caused by the neutral current (which the earth line doesn't carry) causing a voltage drop due the line/contact resistance.
The isolation transformer would have no effect on the neutral current, thus no effect on the voltage difference.

Effective Alternatives
Properly designed power conditioners
offer an effective alternative to the
dedicated/isolated electrical circuit. Each power
conditioner contains three
elements that provide
distinct benefits.
A surge diverter and a noise filter in
each conditioner provide complete protection
against both externally and internally generated
noise and transient disturbances. A low
impedance isolation transformer ensures that
common mode (neutral to ground) voltage
disturbances cannot interfere with system
operation. This is accomplished by placing the
neutral-ground bond adjacent to the electronic
load (the electrical equivalent of bringing the
“mountain to Mohammed”)

System manufacturers, resellers, and
service providers will all appreciate the
business benefits. These include:
•Better power protection
•Fewer system failures
•Predictable electrical installations
