DC Hipot Testing of Motor Stator Windings (IEEE 95)
The DC hipot test is the most consequential offline test you can run on a stator winding. It applies a high DC voltage — well above operating levels — to the groundwall insulation and holds it there. If the insulation fails during the test, you know before the machine goes back into service. If it passes, you have… Read More: DC Hipot Testing of Motor Stator Windings (IEEE 95) »
