The new MicaSonic® BDV oil sensor is developed especially for on-line use in the field and exclusively designed for continuous and repeatable measure of the:

• Current oil temperature [°C] in mineral transformer oil
• Breakdown voltage [kV] at the current oil temperature
• Breakdown voltage [kV] at 20 °C oil temperature according to the IEC standard
• Moisture content [ppm] at current oil temperature

The MicaSonic® BDV is designed to be installed in oil treatment, regeneration and filtration plants, but can also be mounted directly on transformer tanks, tap changers, oil tanks as well as in oil distribution systems.
