The HYDROCAL Offshore (1003, 1005 and 1009) transformer monitoring systems are specially designed for the harsh conditions (salt water, corrosion) on offshore platforms (e.g. wind mill parks).

Monitoring systems for high voltage bushings

HYROCAL BPD is a modular online monitoring system for high voltage bushings.

It supports the measurement of voltage and phase angle on the test tap to derive tan /PF δ of the bushing capacitance.

The measurement of voltage and phase angle on the test tap of high voltage bushings allows to compare tan /PF with factory δ test results for analysing deterioration of the bushings.

Key advantage : Monitoring of capacitance, tan/PF of up to six high voltage bushings (3 or 6 bushings).
