Rugged design, highly sensitive and accurate Partial Discharge sensor for detecting and monitoring partial discharge activity inside Oil Filled and Dry Type Transformers/Reactors.USENS-T is an Ultra High Frequency (UHF) antenna that can measure Electromagnetic PD signals from the inside of transformer.

The sensors are IP68 rated, easy to install on transformer tank and suitable for all types of Transformers. The sensors can easily be bolted on transformer tank (or inspection cover) directly touching the oil or with dielectric window in-between the sensor and oil. Higher sensitivity (up to -90dBm) over wide range of frequencies (200 – 3000 MHz) helps in reducing the cost of PD monitoring, hence higher ROI (Return on Investment).
