High-Voltage Busbar Wireless Thermal Sensing (MITSU-TECH integration)

01 The Problem

In a high-voltage cabinet, three-phase busbars route through the cabinet on porcelain insulators with finger-thick air gaps between them. A wired sensor can't safely bridge those gaps. So the only way to check temperatures was to shut the cabinet down, open it, and point a thermal camera — and shutting the cabinet down is itself a million-dollar problem in a busy substation.

The Risk

HV cabinets have complex three-phase busbar routing where wired sensors cannot bridge insulation gaps.

Detection Gap

Conventional thermal imaging requires shutdown — shutdown is itself a loss.

02 The OctosX Solution

We paired Thermalpas with a partner wireless module (MITSU-TECH) that harvests its own power from the magnetic field around the busbar — no battery, no wiring. Each sensor transmits a reading every few seconds to a gateway on the wall. OctosX's dashboard shows real-time three-phase balance — when one phase warms differently from the other two, the engineer knows immediately.

Sensor & Edge

Thermalpas + MITSU-TECH wireless modules (self-powered via energy harvesting).

Cloud Logic & Alerting

Each sensor transmits to a Gateway; OctosX Cloud displays real-time three-phase balance.

03 The Outcome

A mid-sized industrial substation deployed 30 wireless sensors for about $600K. Before, they did four annual shutdown inspections, each costing about $1.2 million in lost production. With OctosX, those inspections are scheduled only when the data says they're needed. The system paid for itself in Year 1.
