Delta T Alert

Delta T Alert

A Simple Device with Staggering Results

For the majority of electrical switchgear, an annual infrared testing program is the sole measure of electrical system reliability. Infrared testing does a great job of detecting overheating anomalies caused by conditions such as loose connection, overhead circuits and unbalanced loads.

Delta T Alert wireless systems constantly monitor every critical electrical enclosure in a facility and complements existing electrical maintenance programs. The system also offers energy savings by allowing for the timely repair of loose connections that create increased resistance, thus resulting in higher energy costs.

 

Delta T Alert sensors 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 of temperature rises within their electrical enclosures, well before more serious problems arise and provides an easier, more effective way to prevent costly electrical damage and system downtime. In-between these inspections, Delta T Alert continues to monitor and will raise alarm immediately if an anomaly is detected, allowing Thermography testing to be done and corrective action to be taken as necessary.

 

Delta T Alert bridges the gap between your infrared scans by monitoring and reporting critical temperatures within your electrical enclosures on a timed basis and effectively tracks your electrical system enclosure temperatures and sends data for analysis and trending. If a critical issue arises, immediate notification allows for an appropriate corrective action, before costly damage occurs.

 

The system warnings that Delta T Alert provides allow for maintenance technicians to be warned of potential issues causing the elevated internal ambient temperatures. This information and trend data gives maintenance personnel an enormous safety advantage prior to any type of routine maintenance or troubleshooting of possible electrical anomalies within the electrical enclosures.

 

Delta T Alert is a wireless, self-contained temperature-monitoring sensor that attaches to an electrical enclosure cover. The patented, Delta T Alert unit is simple to install and comprises of two temperature sensors one to monitor the electrical enclosure's interior temperatures and the second to monitor the room's ambient temperature where the enclosure is located.

 

Delta T Alert sensors are then 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 of temperature rises within their electrical enclosures, well before more serious problems arise and provides an easier, more effective way to prevent costly electrical damage and system downtime.

 

IRISS IR Windows can also be equipped with Delta T Alert systems. When the temperature differences are above a pre-determined level or significantly different from other electrical enclosures within the system the Delta T Alert will remotely alarm the support engineers, repair teams, etc... with details and the location of the temperature alarm.

 

The maintenance engineers can then go to the identified enclosure and inspect the internal energized and loaded components inside of the electrical enclosure through the IRISS infrared window in complete safety. The infrared scan will allow the engineer to ascertain the exact temperature of the fault and if required conduct the repair once the system is made safe. Once the repair is completed the system can be reenergized and a follow up inspection completed to ensure that everything is correct and then the electrical enclosure can be benchmarked and system reset with new baseline temperature delta.

 

Delta T Alert systems are not just for electrical distribution systems, transformers and switchgear, they are also used in a vast variety of motors, isophase and bus bar systems, mechanical systems, control systems and cabinets.
