Latest Patents
Colombo holds a patent for a "Current detector for surge arrester diagnostic and overvoltage assessment in high voltage substations." This apparatus is designed to sense and measure the high voltage surge arrester current. It includes two toroidal current transformers arranged coaxially with respect to the earth wire of the surge arrester. The device features elements for sensing the current signals emitted by the transformers and converting these signals into digital format. Additionally, it transmits the digital signals to an information network and analog state signals through relay activation. The two toroidal current transformers are associated with elements that sense both normal leakage current and impulsive current. The impulsive current sensing includes a circuit that discriminates between 'switching' and 'lightning' signals based on a signal duration threshold of approximately 35 microseconds.
