isolation from earth Explanation: No, I'm afraid your suggestion would not be correct! In this instance, 'isolement' really does mean 'isolation' Although in theory 'earth isolation' might be used, it sounds slightly awkward to my ears, and in addition, as the possibility of being seen as ambiguous. Hence in this instance I'd recommend this particular form of wording, to avoid any possibility of ambiguity. -------------------------------------------------- Note added at 38 mins (2019-05-09 16:04:30 GMT) -------------------------------------------------- The distance to earth and the isolation voltage are related: the greater the distance, the higher the measured test voltage one may reasonably expect to achieve. -------------------------------------------------- Note added at 5 hrs (2019-05-09 20:35:29 GMT) -------------------------------------------------- Not really, Thomas; there's no element of harmful repercussions. Generally, the system wants important parts to be earthed as a protection, as you say. However, for correct operation, certain parts must not normally be connected to earth, and this measurement in essence indicates the level of protectsion (i.e. voltage level) at which that wanted 'isolation' breaks down and a connection to earth is made — e.g. typically in the case of a lightning strike etc. |
