minimum insulation megaohm
Hi there,
Very thank you for the above information. I need to mesasure the insulation of motor winding to make sure they are working properly. Yokogawa it is the leader in manufacturing these type of instrument but here in Brazil is very expensive so was looking for something a litle less expensive just because I do not use very often. The motors I usualy test are ~3 x 380VAC or ~3 x 440VAC and sometimes from 2,2Nm up to 20,0Nm 400VDC.
Regards,
Fernando
