Two-panel diagram comparing periodic inspection and condition-based maintenance of a high-voltage asset: on the left, calendar-based inspections miss a fault that develops in the blind window between visits; on the right, continuous battery-free condition monitoring catches the same fault at the action threshold and triggers intervention before failure.

Condition-based maintenance vs periodic inspection for HV switchgear: what each really costs, and how to build a business case utilities will actually sign.

Diagram of battery-free busbar hot-spot monitoring inside a switchgear cabinet: SenseID temperature tags mounted on busbar joints detect a hot spot, are read by a UHF RFID reader, and feed per-joint temperature into asset management (CMMS/SCADA).

Battery-free temperature sensors detect busbar hot spots inside live switchgear — no wires, no batteries. How it works, which protocol to choose, and the business case.

Two-panel diagram showing HV asset constraints on the left (sealed, high voltage, long lifecycle, mission-critical, no cables, no batteries) and the seven cross-domain engineering challenges on the right (antenna, energy harvesting, power management, sensor, firmware, communication, software), with a section explaining why the system can't be split across specialists.

High-voltage switchgear, GIS and transformers are sealed, inaccessible, and mission-critical. Monitoring them requires battery-free sensing — and battery-free sensing requires a team that owns the entire HW/FW/SW/RF stack. Here’s why.

Three-level filter for determining whether an asset needs battery-free sensing — Level 1 (sealed, inaccessible, battery-free is the only option), Level 2 (accessible but maintenance is costly, battery-free eliminates a pain point), Level 3 (accessible with standard maintenance, consider alternatives) — with three qualifying questions.

A practical three-question filter to determine whether your monitoring application genuinely needs battery-free sensing, or whether battery-powered or wired alternatives might be simpler and cheaper. Honest guidance on when to call us — and when not to.
