Just wondering if someone could shed some light on the cause & possible resolution on the issue below
I am currently testing a data centre but I have been unable to establish consistent circuit Zs readings.
Using several different testing equipment the result is the same. A different/fluctuating result every time a test is carried out. We have analysed the power supply & this is steady with no harmful harmonic interference.
There are large 1000kW UPS on site but I have never experienced this issue on other datacentre projects
Any assistance any one
can give me in this matter would be greatly appreciated.
