Constant temperature monitoring of electro/mechanical enclosures

01 March 2016

IRISS has addressed the need for wider electrical maintenance safety solutions on electro/mechanical enclosures, with a solution that enables continuous monitoring - both as a stand-alone capability and as an addition to its existing window products.  

Infrared imaging is able to detect thermal anomalies caused by conditions such as loose connections, overhead circuits and unbalanced loads.  However, it provides a snapshot of the faults on the day of inspection, leaving the subject components unmonitored for the balance of the year.

IRISS has added the Delta T Alert to its range of electrical maintenance safety devices (EMSD). This self-contained, wireless temperature monitoring system attaches to an electrical enclosure cover. It bridges the gap between infrared inspections by regularly recording and reporting critical temperatures within electro/mechanical enclosures. 

The Delta T Alert unit comprises two temperature sensors.  One monitors the interior temperature within the enclosure and 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. 

This new technology can also be specified as an integral capability of the company’s range of polymer window products.  This 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.

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.
