Core Component

RFID Wireless Thermal Sensor for Busbar & Switchboard Condition Monitoring

Wireless busbar thermal sensors for switchboard condition monitoring and AI-driven predictive maintenance in Hong Kong — powerless, maintenance-free, and easy to retrofit on busbars, circuit breakers, and cable terminations.

PowerGuard AI RFID wireless thermal sensor

Predictive maintenance, right at the connection point

PowerGuard AI's RFID Thermal Sensor delivers continuous, wireless temperature monitoring for the most critical points inside switchboards — busbars, MCCB/ACB terminals, incomers, and cable terminations. Passive RFID-based thermal sensing removes the need for conventional wired temperature sensors, enabling faster retrofit and easier deployment across existing electrical assets.

Collected temperature data is analysed by PowerGuard AI to identify early signs of abnormal thermal behaviour — loose connections, phase imbalance, neutral stress, overload, and poor ventilation — helping operators move from periodic inspection to true predictive maintenance.

Passive RFID Sensing

Powerless and wireless — no batteries, no cabling. Maintenance-free and easy to retrofit on existing electrical assets.

Continuous Monitoring

Tracks temperature at busbars, MCCB/ACB terminals, incomers, and cable terminations inside switchboards.

Non-Intrusive Retrofit

Compact form factor mounts directly at connection points without modifying the existing switchboard design.

AI-Driven Diagnostics

PowerGuard AI detects loose connections, phase imbalance, neutral stress, overload, and poor ventilation early.

Deployed Where Faults Begin

Field-installed across real switchboards in Hong Kong — directly on busbar joints and cable terminations where thermal anomalies first appear.

Two EMSD InnoPortal Listings

PowerGuard AI / UNS has two complementary solutions listed on the Hong Kong EMSD InnoPortal — the sensing layer (this page) and the AI analytics layer that turns the data into predictive maintenance for main LV switchboards.

Frequently Asked Questions

What is an RFID busbar thermal sensor?

An RFID busbar thermal sensor is a passive, battery-free wireless sensor that measures temperature at busbar joints, MCCB/ACB terminals and cable terminations inside an LV switchboard. Because it has no battery and no cabling, it can be retrofitted on existing switchboards without modification and is maintenance-free over its lifetime.

How does switchboard condition monitoring work?

Switchboard condition monitoring continuously tracks thermal behaviour at the highest-risk points of a switchboard — busbar joints, breaker terminations and cable lugs. PowerGuard AI collects this data wirelessly via RFID thermal sensors and applies AI analytics to detect loose connections, phase imbalance, neutral stress, overload and poor ventilation before they become faults.

Why use predictive maintenance for switchboards in Hong Kong?

Hong Kong's high-density commercial buildings, data centres and infrastructure run electrical systems continuously in hot and humid conditions. Predictive maintenance using wireless thermal sensors reduces unplanned outages, extends asset life, supports EMSD and BEAM Plus operational requirements, and avoids costly emergency shutdowns compared to scheduled-only preventive maintenance.

Can the sensors be retrofitted on existing MCCB and ACB switchgear?

Yes. The sensor is compact and powerless, so it mounts directly at incoming and outgoing terminals of MCCBs, ACBs and incomer cable lugs without rewiring or modifying the existing switchboard design. Installation is non-intrusive and typically does not require extended outage windows.

Is the PowerGuard AI thermal sensing system recognised by EMSD?

Yes. PowerGuard AI / UNS has TWO solutions listed on the Hong Kong EMSD InnoPortal: the RFID Thermal Sensing System (REF S-1317, https://inno.emsd.gov.hk/en/it-solutions/index_id_1317.html) and AI Predictive Maintenance and Performance Optimization for Main LV Switchboard (REF S-1357, https://inno.emsd.gov.hk/en/it-solutions/index_id_1803.html) — together covering both the sensing layer and the AI analytics layer.
