Monitoring, Control and Protection System for Electrical Conductor Using Rogowski Coil and Capacitive Voltage Divider Integrated into a Compact Unit

An integrated and compact mechanism for protecting, monitoring and/or controlling a surrounding and insulated conductor wherein said conductor comprises at least a voltage and current flow provider comprising:

• a Rogowski coil closely surrounding said conductor for sensing and providing an analog signal of current passing through said conductor;
• a capacitive or similar voltage divider-like device sensing and providing a proportional analog signal of the voltage of said conductor and also closely surrounding said conductor, being electrically connected to said conductor and to ground;
• a shielded and integrated circuit board electrically connected to the analog outputs of the signals of both said Rogowski coil and said capacitive voltage divider-like device, said integrated circuit having a calibrating look up table thereon and capable of converting said analog signals to calibrated digital signals of the same, said look up table having calibrated indicia of digital signals based on a predetermined accurate set of values obtained from a known and verified standard, and said integrated circuit board further comprising a memory device,
• wherein said current and/or voltage digitally converted and calibrated signals from said look up tables are stored in said memory, as desired for further comparison and/or end use;
• and
• a data collector for at least some of said analog and/or said digital and/or said calibrated signals, optionally further comprising a means for time stamping said inputted set of said analog and/or digital and/or calibrated signal sets for comparing the same, over time or not;
• and
• said data collector being connected to electric, electro- and/or mechanical means for modifying, controlling, protecting and/or disturbing the flow of current and/or voltage if certain pre-determined conditions are met by said compared sets of signals or to a predetermined set of standard values of such signals.
