摘要： A temperature-sensing apparatus for sensing the temperature of an electrical conductor (31), comprising a sensor frame (210) including a frame body (2101) and a channel (2102) adapted to accommodate the electrical conductor (31). At least a portion of a temperature sensor is received in a chamber (2103) of the sensor frame (210). At least a portion of a thermal contact member is disposed between the electrical conductor (31) and the temperature sensor and configured to enhance thermal-contact therebetween. At least a portion of the thermal contact member is radially pressable against the electrical conductor (31).

摘要： At least some aspects of the present disclosure feature a communication device for propagating an electromagnetic wave around a blocking structure. The communication device includes a passive coupling device to capture the electromagnetic wave, and a waveguide electromagnetically coupled to the coupling device. The waveguide is disposed around the blocking structure. The waveguide has a resonance frequency matched with the coupling device. The waveguide is configured to propagate the electromagnetic wave captured by the coupling device.

摘要： Systems and methods for directly sensing, measuring, or monitoring the temperature of an electrical conductor (31) of a power cable (10), are provided. A surface acoustic wave (SAW) temperature sensor (20) is used that includes a substrate (20S) with a transducer (20T) disposed thereon. The transducer (20T) conducts conversion between an electromagnetic signal and a SAW signal that propagates on the substrate (20S). At least a portion of the substrate (20S) is disposed in thermal contact with the electrical conductor (31) such that the SAW signal varies with the temperature of the electrical conductor (31).

摘要： Provided is a system for directly sensing, measuring, or monitoring the temperature of an electrical conductor (31) of a power cable (10). A temperature sensitive capacitor (21C) is disposed in direct thermal contact with the electrical conductor (31). The temperature sensitive capacitor (21C) includes a dielectric material that has a dielectric constant variable with the temperature of the electrical conductor (31). The temperature of the electrical conductor (31) can be sensed, measured, or monitored by measuring the capacitance of the temperature sensitive capacitor (21C).
