HYDROCAL BPD is a modular online monitoring system for high voltage bushings as well as partial discharge of bushings and the active part of power transformers. Bushing monitoring supports the measurements of voltage, current and phase angle on the test tap to derive tan δ / PF and bushing capacitance as well as electrical partial discharge measurement acc. IEC 60270.
