Abstract: A power harvester having a current transformer configured to be inductively coupled to a current conductor and a circuit for delivering power to a load. The transformer core has two sections joined together and separable from one another at interleaved portions, allowing the transformer to be installed around the current conductor. The circuit includes a rectifier coupled to the transformer and a transistor coupled in series between the rectifier and a load. The transistor receives an output current from the rectifier and provides power to the load. A resistor is coupled to the transistor and the load, and the transistor and resistor provide for limiting of the power to the load over a wide range of the conductor line currents.

Abstract: A solid state light having a solid state light source such as LEDs, a light guide having an enclosed interior volume such as a bulb shape without vents, and a thermal guide. The light guide is coupled to the light source for receiving and distributing light from the light source. The thermal guide is at least partially contained within the interior volume with an air gap between a portion of the thermal guide and the light guide. The thermal guide provides for thermal conduction from the light source and dissipating heat through convection and radiation for cooling the light.

Abstract: An integrator circuit for a current sensor such as a Rogowski coil. The integrator circuit includes an integrator having an input for receiving a signal from a current sensor and having an output providing a voltage signal. A high-pass filter has an input coupled to the output of the integrator and substantially removes the DC content from the voltage signal. A feedback loop has an input coupled to the output of the integrator and to the high-pass filter, and has an output providing the DC content of the voltage signal back to the input of the integrator. The integrator circuit can detect large current steps in the line conductor being monitored and can be used for line fault detection.
