The CTPD Wireless Passive Temperature & Partial Discharge Multimodal Sensor (HJ-CTPD-A1) is a new-generation wireless, passive, integrated online monitoring device that simultaneously measures temperature and partial discharge. Building on the original CT-powered wireless temperature monitoring product, it integrates wideband electromagnetic pulse-based partial discharge detection. It is suitable for online insulation condition monitoring of medium- and high-voltage electrical equipment such as switchgear and transformers.

Key Features

CT electromagnetic induction power harvesting, fully wireless and passive, ultra-low power consumption with advanced energy storage

Directly samples electromagnetic coupling from the primary circuit, obtaining high signal-to-noise ratio local signals

Simultaneously monitors two highly correlated signals — temperature and partial discharge — significantly improving partial discharge identification accuracy

Distributed array deployment enables relative positioning of the partial discharge source
