“…As shown in Fig. 1, several existing systems have been proposed for grid thermal monitoring, including infrared radiation (IR) imaging, surface-acoustic-wave (SAW) sensing, fiber-Bragg-grating (FBG) system, and wireless sensor powered by current transformers (CT) [1], [4]- [7]. However, these solutions are still not widely deployed due to their respective drawbacks.…”

This paper presents an ultra-high-frequency (UHF) passive sense tag for electrical grid and substation thermal monitoring, with emphasis on the tag system optimization and the design of a low power embedded temperature sensor. The designed tag achieves a sensitivity of −12.3 dBm under active temperature monitoring operation, which is the state of the art among existing UHF passive temperature sense tag products. The sensing inaccuracy of the tag is ±2.5 • C (3σ) from −25 to 120 • C after a low-cost wireless single-point trim. An antimetal ceramic-packaged tag was tested by attaching to a ring main unit in the substation and complete tag system demonstrated robust wireless operation with a sensing distance of 3.5 m. The combination of batteryless and wireless operation, high sensitivity, wide sensing range, and small incident-power-dependent error (±0.2 • C) makes this tag suitable for the target applications. Index Terms-Antimetal antenna, CMOS temperature sensor, grid thermal monitoring, radio-frequency identification tag (RFID) temperature sense tag, relaxation clock generator, ultra-high-frequency (UHF) RFID.
