Insulation Resistance Testing theory this is well documented due experts, all from this market sector.
Rule of thump this is double testing voltage than operating voltage.

But in this market of Insulation Resistance testers, there is product offerings which differentiate at Max testing voltage.
What any one interested to buy a new Insulation Resistance tester within 2017 must be aware, this is of which applications he will get evolved with?

Recently technology of solar energy (which this is still under development), it started using 1500V DC this be transformed to Grid energy.
Because of that need for 3000V testing voltages, manufacturers started to produce testers with such higher voltages.

Prior this new high voltage application, I am aware of one which is also rare but not unknown, and this is ventilation electric fans them operating  at 1000V and serving in underground excavation sites.

One picture equals to 1000 words, therefore here is the picture.
