Installation Cases

01

Switchgear

In modern industrial and commercial environments, switchgear is the central hub for safe power system operation. However, internal connections, switches, and busbars are prone to overheating under high loads due to poor contact or aging— leading not only to power outages but potentially serious incidents such as fires. PQSENSE temperature monitoring equipment is designed to address this critical challenge. Miniaturized wireless temperature sensors are installed directly at key heat-generating points inside the switchgear, such as circuit breaker contacts, cable terminals, and busbars, enabling real-time, high-precision temperature monitoring.

Busbars
Carries high current; oxidation or loose connections cause overheating
Circuit Breakers
Frequent switching wears contacts, increasing resistance and heat
Cable Terminals
Oxidation or loose connections increase resistance, causing overheating

Ring Main Unit

Ring main units are essential components in medium-voltage distribution systems, widely used in urban power grids, residential complexes, and industrial parks. Due to their compact design and sealed structure, internal space is limited—once switches, cable terminations, or busbars develop thermal faults, heat cannot dissipate easily, faults escalate rapidly, and maintenance becomes difficult, posing a serious threat to power supply reliability. PQSENSE temperature monitoring solutions provide ideal wireless temperature monitoring for RMU switches, cable terminations, and busbars.

Busbars
Sealed enclosure limits cooling; poor contact accelerates overheating
Cable Terminations
Carries MV current; contact degradation leads to overheating

Transformer

As critical equipment for power transmission and conversion, transformer safety and reliability are vital to the entire power system. Transformer failures often originate from insulation aging and localized overheating in windings, leads, or core components. Once temperatures exceed safe limits, permanent equipment damage may occur, causing significant economic losses and power supply interruptions. PQSENSE temperature monitoring solutions provide passive wireless monitoring for transformers, particularly for critical heat-generating points such as bushings and terminals on oil-immersed or dry-type transformers.

Low Voltage

In factories, commercial buildings, and infrastructure, low-voltage electrical systems are fundamental to end-equipment operation. Although voltage levels are lower, thermal fault risks at connections and switches remain, especially in motor control centers, distributed panel boards, and heavy-load cable connections. These thermal faults can equally cause downtime, production interruptions, and even fires. PQSENSE temperature monitoring equipment provides cost-effective early warning monitoring for low-voltage environments.
