Holy ----!.....this is covering domestic property....
Taught him all he knows ?wow, that is still quite high for domestic.
I try to keep out of domestic but have rarely seen above 2ka when doing pfc tests at that sort of install.
strangely enough, the times where I have had huge figures are in buldings that have ther own on site transformers and the measured value is just balls.
3 ft from the 1Mw transformer and you get a silly reading like 1.8ka
that is when you have to enquire with transformer people and discover that 20 x that figure is possible.
the theory behind it is a little over my head, but the basic premmise is that the meters we use to measure pfc work on resistance and when you get real close to the transformer you really need a much better piece of kit that can measure/estimate the impedance of the circuit.
like i said a little over my head!!
