Constant monitoring of electro/mechanical enclosures

The unit is simple to install and comprises two temperature sensors. One monitors the interior temperature within the enclosure; the other, the ambient room temperature. Both are configured to collect data on a daily basis, at specific time intervals. 

The data is wirelessly transmitted for analysis and trending and warns the operator if the internal temperature rises above pre-set thresholds. Remedial action can then be taken before the problem becomes serious and warrants unscheduled system shutdown, incurring costly downtime.  

This new IRISS technology can also be specified as an integral capability of the company's polymer window products. The combination ensures the problem is verified with no operational disruption. The on-board Delta T Alert system sends a remote alarm giving the location of the problem and temperature details. The maintenance engineer can then conduct a thermal scan of the live system, through the IRISS infrared window, in complete safety.

Once the repair is completed and the system re-energised, a second infrared inspection will confirm the fault has been eliminated. The electrical enclosure can then be benchmarked and the system reset with the new baseline temperature delta.

The Delta T Alert monitoring system is said to complement and enhance the safety and effectiveness of an electrical maintenance programme and its application is not restricted to electrical distribution systems, transformers and switchgear. It can also be used to monitor the health of a wide variety of motors and mechanical equipment, isophase and bus bar systems, controls and other enclosed systems.
