How do you perform a megger test?

Answer

A megger test is used to look at the insulation properties of motor windings, electric wiring, high power antenna mounts, and other similar items. The voltages are a lot higher than they are with a normal Volt-ohm meter. You will turn the device off and connect it to a source of power. The circuit breaker being testing should be closed and then disconnect the line-side circuit. Connect the output terminals and turn on the test set. Get the desired current and make any necessary adjustments. Then, you will hit the 'start' button and get your readings.

Michael, Good question, yes isolate incoming power. If you have a 460 volt motor with three leads 500 is good enough. If all the choices you have are 1000 that is OK also. Three leads

Look into "load testing" You basically need to log all the database queries your app does to some file, use the app for a while, then replay those queries to the database
