Row of electric power distribution switchgear cabinets

Preventing switchgear failures is tough –

over its 20-year service life. High voltages and high currents put strains on electric switchgear that accelerate deterioration and that increase the danger of catastrophic failure. While power distribution equipment is critical to our modern lifestyle, it is also incredibly dangerous to maintain. The risk to human life can be extreme when switchgear fails.

Temperature monitoring
is essential for safety –

Temperature is the critical indicator to protect human life. But, most temperature sensors require wiring for power and communication. Wiring is not practical inside switchgear equipment where it contributes to arcing risks. Smart Passive Sensing™ technology enables wireless, battery-free sensors that pinpoint failing switchgear components and anomalous operation. The RFM5107 delivers continuous temperature monitoring to protect critical equipment, and issues alerts over MODBUS for easy integration into safety and security networks.

RFMicron RFM5117 Industrial RAIN-UHF Reader for USB-MODBUS

Switchgear Temperature Monitor System

The system includes the all the hardware to monitor switchgear equipment, including reader, display module, antennas, cables and rugged temperature sensors. The system reader is initially configured using USB but normally operates over an RS485 serial link using a MODBUS protocol for maximum compatibility with industry standard SCADA software. The USB interface facilitates sensor registration and naming of up to 12 temperature sensors per reader. The USB interface also provides immediate sensor data and wireless signal strength statistics to speed the sensor installation process. Once the system is installed, the display module reports current temperatures so that local switchgear maintenance teams always know the equipment condition. The display module includes NO and NC relay contacts for audible alarms, lights, etc. One magnetic mount antenna is needed in each metal enclose switchgear chamber. For large medium-voltage (MV) switchgear three antennas may be needed to read sensors in the busbar area, the contact assembly area, and in the cable run area of the unit. The wireless reader and the display module are normally installed in the low-voltage chamber.

Wireless sensors

Rugged wireless temperature sensors built using Smart Passive Sensing™ technology, are attached directly to complex components and busbars using the integrated adhesive strip. Lug-mounted sensors can be bolted directly to heavy-duty equipment. Smart Passive Sensing technology eliminates batteries, maintenance, and wiring, making these sensors suitable for high-voltage environments with significant arcing risks where sensor wiring is not an option.

Continuous monitor

Temperature at the component level is an excellent indicator of switchgear condition, but this requires that access ports and doors be opened to expose live, energized equipment. This is exceedingly dangerous. The RFM5107 system continuously monitors from inside the enclosure and alerts on pending failures before equipment is damaged. Continuous monitoring provides additional time to deal with infrastructure hacking while it is still in progress.

Improves safety

Human errors leading to death can be nearly eliminated if the enclosure doors are kept closed when the system is energized. Small sensors are easily placed on components obscured from IR inspection. Maintenance teams will know more before opening enclosures and may be able to eliminate live, energized inspections using continuous temperature monitoring. Dynamic load anomalies become detectable and can trigger safety alerts to exit the area.
