Hi Alex,
We monitor almost 400 20amp and 30amp 110V and 208V circuit breakers in
our data center in San Deigo. We utilize a system called Data Trax which
is tied into our Remote Power Panels and monitoring gear made by a
company called Invensys. Our power comes from our UPSs, ties into
redundant PDUs and then hits the RPPs where we pick up load with
inductive donuts.
In our case, the Data Trax system alerts us is the usage goes over a
certain amperage that we set. As we sell 1/3 cabinets and only allow
customers 5.33 amps, we set those to alert (via e-mail, trap and visual
warning in my NOC) when those customers go over 5 amps. On standard 20
amp circuits, we alert at 15 amps. The customer is also notified at the
same time via e-mail so they can take corrective action.
We utilize the same system to monitor our DC plants as well.
The system works very well for us. Hope this helps a bit. Let me know if
I can answer any other questions.
