question about VirtualDynamics Reference PC

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.

Some questions:

1)What two points are you measuring the "ground voltage" between?
2)When you make this measurement, is the power cord connected to a component?
3)If so, is the component connected via interconnects to other components?
4)If so, do the other components have 3-prong power cords, that are plugged in to the ac?
5)Is/are the component(s) turned on when you are making the measurements (assuming the cord is connected to a component for the measurements)?
6)What voltage fluctuations are you referring to? A power cord will not have any effect on voltage fluctuations of the incoming ac line (it is not a voltage regulator). It will only affect fluctuations in the voltage loss between one end of the cord and the other, that may result from fluctuations in the amount of current that is drawn through the cord by the component. That voltage loss will be small if the cord is of adequate gauge.

Some answers to the questions.The power cable is connected in to the wall and female into the FLUKE1711.The Fluke measures the voltage ,it provides the results in a number of representations.The voltage display shows the voltage vs time.Two displays,one of the main voltage and one of the ground voltage.In all measurements involving conditioners as well a Stage3 pc,the resulting ground voltage is between 0.5and 2.0 varying as a function of time.Only the VD PC have the voltage at around 60v.As far as power cables altering the voltage ,when the statistical distribution of the voltage is represented it shows the standard deviation for the voltages and the value is increased or decreased with different cables,I cannot explain that neither.As for conditioners example the Weizi "conditioner" increases the average voltage,and reduces the ground voltage,while the Shunyata decreases the average voltage and the burmester keeps it at 120 with smallest spread/variations.I am still at a loss I wonder if Rick Schultz the cable designer could help?
