Web14 okt. 2016 · By correct positioning, thermistors can be located close to the thermally critical areas, or hot-spots, of the winding, where they closely track the copper temperature with a certain time lag, depending on the size of the thermistors and how well they are installed in the winding. Web24 feb. 2012 · Megger gives required direct (DC) voltage across the insulator, and it also shows the resistive value of insulation directly in M – Ω and G – Ω range. We generally use 500 V, 2.5 KV and 5 KV megger depending upon the dielectric strength of the insulation. For example, we use 500V megger for measuring up to 1.1 KV rated insulation.
Web27 feb. 2012 · To do the meggering we have to dismantle the VFD's and pull them from the tabs. It is a lot of work. I would like to ask if we can megger the motor whilst it is connected to the drive as it would save a lot of time and wear and tear on the connections and bolting of the VFD's. We cannot disconnect at the motor as that is an even bigger job. Web1 jan. 1996 · Basically, there are three different tests that can be done using a megohmmeter. 1) Insulation resistance (IR).
