IR scanning for High Voltage panels
IR scanning for High Voltage panels
(OP)
Good day,
I'm interested to know what is the common industrial practice to scan HV panels? Appreciate your thoughts.

OSHA has some detailed guidance which may be more restrictive than this.

Basic NFPA-70E requirements imply that just opening a door for observation requires appropriate arc-flash PPE. The IR equipment manufacturers are working to come up with solutions that don't require opening of doors.

dpc, u mentioned on the observation ports. what are those? would appreciate if u could provide me with the links to find those.
actually i have another question. recently, we have a unit of ACB (Air circuit breaker) that burnt down due to loose connection at one of the terminals. this is a ABB Sace F5C slot-in type ACB. we plan to monitor all the ACBs using the IR thermography but the problem is the terminals are inaccessible. it's protected by a layer of PVC panel and to top it with the cabinet door. I'm wondering is there anyone that has successfully monitor ACB of this type? if so, how?

There are two kinds of observation ports.
One is a fisheye port offered by Mikron. Relatively inexpensive per port but you have to have the Mikron camera and special attachment to use it. Look at www.mikroninfrared.com
Another type of ports are windows selected as transparent to infrared frequencies. These are much more expensive per port but can be used with any camera. Google for Hawke windows or check snellinfrared.com message boards which have a lot of discussion (also dpc may provide some more ino.
With either option you should review for yourself whether you consider it safe.

Certainly not risk-free, but probably lower risk than opening the doors.
