What's your strategy for machine failure? 

Implementing the right maintenance strategy impacts your facility's bottom line. With GraceSense Hot Spot Monitor (HSM), you will be able to find faults before they occur. The HSM is a non-conductive temperature monitor and alarming device that identifies hot spots, enabling you to predict failures in electrical equipment. It can spot temperature abnormalities in electrical connections of power distribution systems. Identifying faults before they occur saves money when unplanned outages, service interruptions, and equipment failures are avoided. Companies using predictive maintenance have seen a 35-45% reduction in unplanned downtime. 

The HSM:

  • Monitors, logs, alarms, and trends temperature variations that tell of  potential faults about to happen
  • Allows users to set, monitor, record, and retrieve the temperature data of critical connections in electrical equipment
  • Non-conductive fiber optic technology allowing simple field installation in low, medium, and high voltage electrical systems up to 80kV
  • Remote monitoring capabilities - eliminating workers' exposure to high incident energy


Current flowing through poor electrical connections is a major cause for electrical hot spots. Some critical hot spots are inaccessible by infrared thermography, and therefore, go unnoticed. The integrity of bolted connections, potential hot spots, can be compromised when electrical equipment is subjected to wide load fluctuations or high harmonics. 

  • Low voltage/medium voltage switchgear
  • Low voltage/medium voltage MCCs and Drives
  • Motors, generators, and dry-type transformers
  • Bus ducts and busbars connections
  • High current junction boxes
