Critical Power Assets Thermal Monitoring 

What are Critical Power Assets?

Switchgear , Transformer, Ring Main Unit Temperature Monitoring Solutions, Crtical Power Assets Temperature Monitoring

Critical Power Assets are equipment that is used to provide and maintain a steady and reliable electricity supply to industrial, transportation, and residential facilities. These assets typically include Switchgears, Bus Ducts, Transformers, Cable Distribution Boxes, and Ring Main Units, which are located in special electricity control rooms and substations within these facilities. 

Asset Applications up to 60kV:

  • Switchgears

  • Ring Main Units

  • Main Switchboards

  • Cable Terminations

  • Transformers 

  • Variable Frequency Drives

  • Bus Ducts

  • Capacitor Banks
    ....and more.

Some Industry Applications:

Why Monitor Power Assets? 

  • Temperature rise accounts for the top reasons for preventable asset failures globally. 

  • Temperature rise occurs due to loose connections, overloading, corrosion, operational wear and tear, and often develops unknowingly. 

  • Assets face increasing load demands due to ever increasing production schedules, leading to a higher rate of degradation, 

  • Asset failures often occur suddenly, without warning, and can lead to sudden power outages at your facility, which can disrupt production schedules, leading to heavy financial losses.  

  • A single asset failure can cost up to hundreds of thousands in repair costs, delayed deliveries,  customer claims, and liabilities for human injury or death. 

  • Traditional periodic inspection methods do not always catch or identify problems, and can be lethal when exposing technicians to live equipment that are in an overheated state. 

  • Problems often develop unknowingly between physical inspection periods, leading to  preventable conditions that lead to a catastrophic failure.

Our Solution

Our Solution:

Axzon's RFID, battery free Smart Passive Sensing (SPS) Critical Power Assets temperature / hotspot, monitoring solutions is designed to offer electrical maintenance teams with a powerful predictive maintenance tool which alerts them in real-time of any developing temperature rise problems. . 


Comprising of three main components: RFID Temperature Sensors, Antenna, and Reader, Axzon's solutions are designed to accurately monitor power assets for temperature rise and hotspot conditions. 


As each RFID sensor has its own unique RFID code, and when combined with Axzon's intelligent reader, this system produces highly accurate readings and is not affected by external events such as electrical transients or noise. 

With the advantage of having the widest range of sensor types and sizes in the industry, Axzon sensors can provide monitoring coverage where no other sensing solutions can.


Marine Terminal Operations

What are the benefits?

  • Reliable and accurate 24/7 total monitoring of your critical power assets.

  • Mitigate asset failure due to temperature rise. 

  • A powerful predictive and preventive maintenance tool, providing actionable real-time data on asset health.

  • Quick and Easy integration onto new or existing assets.

  • Reduction in maintenance costs.

  • Reduction in operational downtime.

  • No monitoring blind spots. - Widest sensor types and functions in the industry. 

  • Does not expose personnel to dangerous live assets. 

  • Competitive costs for quick Return-On-Investment periods.

How Does It Work?

How Does Smart Passive Sensing (SPS) Work?

Given the typically limited shutdown times, Axzon's Critical Power Assets monitoring solutions is designed to be quickly and easily integrated onto new or existing power assets. There are 4 key steps to this process:

  • Install temperature sensors at required locations (Busbar, Circuit Breaker, etc)

  • Install Antenna 

  • Connect Antenna to the Reader

  • Power up, and integrate reader to the SCADA interface or Digital Panel Meter.
