question about VirtualDynamics Reference PC

I have recently been using a FLUKE 1711 to compare Power cables and power conditioners.I have tested the Shunyata Hydra V-Ray,a weizi,Burmester,and now the Virtual Dynamics Reference cables.I test the component for about 12 -24 hrs for good statistics.My wall voltage fluctuations are terrible,of what I tested,each have some distinct characteristics .Anyone interested in more detail can contact me. I have chosen to test the VD cables as they have a distinct sound in my system when connecting power amps,way too much boomy bass.What I am primarily looking at is the Voltage fluctuation and ground voltage which should be close to zero atleast under 2.0volts.With the exception of the VD cables all the measurements demonstrated an acceptable to excellent ground voltage. However the VD cables had a ground voltage of of approximately 55-60 volts,ie 50%of ground voltage,Any explanation???

Sounds like neutral and ground are reversed

You get the same result if the ground is completely open too. Have you checked all wires for continuity?

Thanks for the input.I connected another VD cable same results.The ground reads 59 volts + or- 1.volt.Could it be a strange design.If the cables were connected to the wrong prongs would the component being powered by it would function? The cable is quite good at reducing voltage fluctuations.Correction to my form,the cables are Revelation model and also a master series,both are unwieldy mechanically unless you are a weight lifter.

What are the voltages between neutral and ground and hot and ground. Don't forget neutral to hot!! In a balanced configuration (like my isolation transformer) you get (assuming 120V) 60V between neutral and ground - 60V between hot and ground BUT 120V between neutral and hot. I have seen in some occasions when the ground is open get the same readings. DID YOU CHECK CONTINUITY?

I had the ground lifted (opened) on my 1 power cords because of a hum. That fixed the hum but it turned out it was my integrated all along. Replaced it and the hum is gone even without floating any grounds.
