Abstract: A sensor system for an electric power asset includes a sensor instrument coupleable to sensors associated with the electric power asset to receive sensor signals therefrom, and an antenna connection cable coupled to the sensor instrument. The antenna connection cable includes a cable sheath and a plurality of twisted pair signal carriers contained within the cable sheath to carry sensor signals received from the electric power asset. A first subset of the plurality of twisted pair signal carriers carry antenna signals and a second separate subset of the plurality of twisted pair signal carriers carry signals for partial discharge monitoring.

Abstract: An industrial process field device includes an active component, a switch, a switch monitor, and a controller. The active component may be a sensor configured to sense a process parameter, or a control device configured to control a process of the industrial process. The switch is electrically coupled to first and second terminals and is configured to electrically connect the first and second terminals when in a closed state, and electrically disconnect the first and second terminals when in an open state. The switch monitor is configured to detect a current state of the switch corresponding to the closed or open state, and generate a state output indicating the current state. The controller is configured to set the switch in the open or closed state, and generate a notification based on the state output that indicates at least one of the current state of the switch and a condition of the switch.

Abstract: A pipe diagnostic system includes a sensor capsule, measurement circuitry and a controller. The sensor capsule is configured to be coupled to an exterior surface of a pipe and has at least one temperature sensitive element disposed therein. The measurement circuitry is coupled to the sensor capsule and is configured to measure an electrical characteristic of the at least one temperature sensitive element and provide an indication of the measurement. The controller is coupled to the measurement circuitry and is configured to obtain a transmitter reference measurement and employ a heat transfer calculation with the transmitter reference measurement and the indication to generate an estimated process fluid temperature. The controller is further configured to obtain an indication of process fluid temperature and provide a pipe diagnostic indication based on a comparison of the estimated process fluid temperature and the obtained indication of process fluid temperature.

Abstract: A process fluid temperature calculation system includes a first temperature sensor disposed to measure an external temperature of a process fluid conduit. The process fluid temperature calculation system has a stem portion having a known thermal impedance. A second temperature sensor is spaced from the first temperature sensor by the stem portion. Measurement circuitry is coupled to the first and second temperature sensors. A microprocessor is coupled to the measurement circuitry to receive temperature information from the measurement circuitry and to provide an estimate of temperature of process fluid within the process fluid conduit using a heat flux calculation.

Abstract: A sensor module for monitoring an asset in an electrical power generation or distribution system includes a module body, a sensor, a sensor near field coupling structure, and an interrogation near field coupling structure. The sensor is supported by the module body, arranged to sense a parameter of the asset and configured to generate a sensor output relating to the parameter. The sensor near field coupling structure is connected to the sensor and supported on a first side of a module body. The interrogation near field coupling structure is supported on a second side of the module body. The sensor output is transmitted from the sensor near field coupling structure to the interrogation near field coupling structure. The sensor module is configured to provide electrical isolation between the asset and a monitoring circuit configured to receive the sensor output through the interrogation near field coupling structure.
