BM

The Bushing Monitor - BM is a device which online monitors the insulation state of capacitive bushings, emitting alarms in case of any issue, both in an incipient phase or in an advanced stage, avoiding catastrophic failures through measuring the leakage current and algorithms that supervises the tangent delta and capacitance of the dielectric, as well as the evolution trends of these algorithms. It has two main modules:BM - MM (Measuring module): Responsible for performing engineering calculations; BM - HMI (Interface module): Responsible for making data available and issuing alarms from BM-MM.
