HSM 600_Application_8 (1)
  • Direct Monitoring: Thermistor-based sensors (rated up to 600V) are mounted near critical components to continuously monitor potential failure points (PFPs).
  • ΔT Trending: Measured values are compared against ambient for early fault detection in compliance with NFPA 70B.
  • Phase Differential Monitoring: Notification when temperatures differ significantly between monitored phases.
  • User-Friendly Configuration: No apps required. Browser-based web utility eliminates the need for proprietary software.

  • Direct Monitoring: Sensors are permanently installed at critical electrical connection points where failures typically begin.
  • Continuous Monitoring: Capture thermal changes caused by load shifts, vibration or loose connections that inspections often miss
  • Real-time Alerts: Notification when temperatures exceed thresholds
  • Fiber-optic probes: Measure temperature directly at the source, making them immune to electrical interference
  • Temperature Trends: Tracked over time help teams identify abnormal heat rise early

Applications

 Thermal abnormalities in electrical equipment are commonly caused by loose or deteriorating connections, vibration, load imbalance, harmonics, and overloaded circuits. Continuous Thermal Monitoring helps detect these developing conditions early across switchgear, motor control centers, power distribution systems, transformers, bus ducts, and other critical electrical assets.

The Risk Between Inspections

  • Unplanned Downtime is Expensive

    Unplanned electrical outages cost thousands per hour in lost production, emergency repairs, and equipment replacement, making early detection critical to equipment longevity.

  • Thermography Captures Moments, Not Trends

    Infrared thermography provides a snapshot during inspection windows, but developing issues between scans often go unnoticed and each energized panel opening introduces arc flash exposure.

  • Continuous Monitoring Closes the Gap

    Continuous Thermal Monitoring detects abnormal temperature trends early, reduces reliance on routine inspections, and minimizes unnecessary energized access improving both reliability and safety.
