摘要： A sensor package includes at least one conductive trace providing a voltage common and a base supporting the at least one conductive trace. A conductive extension extends from the base so as to contact a conductor of an insulated conductor when the sensor package is mounted on an insulator of the insulated conductor and thereby provide an electrical connection between the conductive trace providing the voltage common and the conductor.

摘要： A method for determining a dynamic rating for a conductive path includes using a sensor to measure a value for a load parameter and selecting a heating process associated with the load parameter. A rated temperature change is changed by removing temperature changes due to a heating process other than the selected heating process to produce an impaired rated temperature change. A thermal load percentage is determined from the impaired rated temperature change. The thermal load percentage and the measured value are then used to determine the dynamic rating for the load parameter. A method also includes measuring a temperature rise, a current, and a voltage on the conductive path multiple times. Using at least two basis functions and the multiple measured temperature rises, currents and voltages, the values for at least two variables are determined. Trends in each variable are determined to determine a condition of electric equipment.

摘要： An apparatus for generating electrical discharge includes a component that generates an electrical discharge, a measurement circuit configured to measure a magnitude of the electrical discharge, and a controller configured to control the magnitudes of the electrical discharge. A method for controlling a reference partial discharge signal in an electric power system includes generating a partial discharge for built in self test, controlling an expected discharge magnitude of the partial discharge, and includes measuring an actual discharge magnitude of the partial discharge.
