I've got an ungrounded 600VAC system of motors that is only operated periodically, and it has some offline ground fault detection. However this only is functional when the control power for the system is active, and therefor not always available, since this system is only activated periodically. The HMI's associated with the monitoring system are only powered on when the system is activated, which is usually a few days before use so that it can be checked out.
I are debating whether we should re-design so that the ground fault system is always on and has some kind of permanent notification, or whether its simple enough for the operators to just flip it on a few days before use and then find out if a ground fault had developed. I'm concerned that if we go to a lot of trouble to make the ground fault detection system always operational, that nobody will really pay attention to that system until they are ready to use it anyway, which is what happens right now (considering that this system is isolated from other systems)
Has anyone dealt with a situation similar to this or have any opinions or considerations?
Thanks!
