Problem Statement: Questions about motors (practical tests)
Relevant Equations: synchronous/induction motors
Hey guys,
Some practical questions about motors :)
Let's admit I have to test one stator winding phase (in high voltage, we test one at the time). During this test what do you do with the others phase ? We let them open right ?
I have to test a 3 phase machine by applying 12kV DC and AC for 10min.
The more dangerous test to the winding is the DC right ? I don't remember why ...
When you finish these tests you remove the test leads. What is the most dangerous for the operator ? Is it to open leads after AC or DC testing ?
I think to open leads after AC testing is the more dangerous.
I have also to suggest some security procedures to make it the safer. I don't have any idea for this ... I think maybe to put thick cables for the safety ground right ?
Thaksfor the help !
