Delta or WYE 3-phase circuit? John Shinn, P.E.
-----Original Message----- From: owner-emc-p...@majordomo.ieee.org [mailto:owner-emc-p...@majordomo.ieee.org]On Behalf Of Arno van Kesteren Sent: Friday, March 22, 2002 12:31 AM To: emc-p...@ieee.org Subject: Phase loss Dear All, When a circuit breaker trips on excessive ground current (>250 A) and while measuring that one of the 3 phases doesn't carry any current (while the others have the same current as the protective ground) what could be the problem ? I was thinking of a sudden phase loss and would like to know how that could happen without any loose connections in the system. The system itself contains a 3-phase rectifier.
