Wireless Thermal Monitoring Solutions for Low and Medium Voltage Switchgear
- Temperature sensors installed in equipment interface with monitoring units to remotely report overheating for proactive planning and minimize downtime.
- Designed for continuous monitoring of ambient bus and power connections through measurement of wireless temperature sensors that require NO power or wiring.
- User-configurable alarms, both limit and differential via optional HMI monitoring system.
- Industry standard Modbus RTU communications to customer SCADA
Why Measure Temperature
- Bus joints and power connections are subject to overheating due to overload, corrosion, loose connections and environmental conditions
- Increase in heat will intensify until complete thermal failure of the connection or nearby insulation
- Next generation continuous Thermal Monitoring in lieu of traditional IR windows and periodic thermal imaging.
How it Works
Temperature sensors are powered by RF signals through the Thermal Monitoring Module and antenna Temperature Interface Module.
The Thermal Monitoring Module provides the measurements taken from the sensors and immediately makes available the data through industry standard communication protocols for critical equipment monitoring.
Temperature Measurement Methods
Periodic, 1 or 2 times per year
Unable to measure under boots and locate all bus joints and connections
Requires engineering personnel
Dangerous if measuring with live energization of switchgear requiring high level PPE
The IEM Approach
Safety: Directly mounted wireless sensors to critical measuring points while ensuring all safety requirements are maintained.
No Maintenance: 20+ year life expectancy
Easy Installation: Sensors do not require “line of sight” and can be mounted under insulation boots or tape
Reliability: Sensors designed to withstand harsh environments
