WebOn the one hand you are talking about a dielectric (which is non-conducting by definition and hence has infinite resistance) and on the other hand you mention a conductivity σ … WebMar 8, 2009 · edison123 (Electrical) 8 Mar 09 23:33. The dielectric test is a hi-pot test (ac or dc) to check the strength of the insulation to withstand the rated voltage and occasional surge voltages. Insulation resistance test (aka meggering) is to check the general condition of the cables and other electrical machines to see if they are wet, contaminated ...

WebWe would like to show you a description here but the site won’t allow us. Webtric strength of an insulating material varies with the thickness of the test specimen. Therefore, tests on specimens of differ-ent thicknesses are not comparable. The thickness used shall be the average thickness of the sample measured as specified in the specification involved. 5.2.2 The dielectric strength of most insulating materials var- how to remove hard water stains from marble
