Insulation resistance/impendance of non-conducting floors and walls???

[paulthemagpie]

Hi guys,

Im trying to find out the instrument used and the units it measured in for Insulation resistance/impendance ofnon-conducting floors and walls

am i right in saying

Instrument used =Magneto-ohmeterand test electrodes

Units = ohms and in 0.01's

I have only ever done this test at an hospital and then I was only observing but if my memory isn't failing me I think it was done with a normal insulation resistance tester

For a normal LV installation Ithink you set the meter to 500volt for HV you set it to 1000, as I recall.But I can't for the life of me remember what values you should be expecting

Never tested such a location myself before, but this seems to answer your question...
5.1.2. Resistance measurement of non-conductive walls and floors for Measurements on Electrical Installations Safety

Note, you need special electrodes.

Now why didn't I do that lol

An amazing tool, that Google!

I have to admit Archy how much I love the tinternet I often just plain forget that you can google most things and get the answer.......................... We are all becoming redundant

Similar tests using the same test equipment are required for both conductive and non-conductive flooring. At one time UK Hospital operating theaters had non-conductive flooring, but these day's it 's conductive flooring to meet the IT derived PA/PE earthing requirements.

Damn Archy, that's one of the best manuals I've seen for a long time.
