摘要： A protection relay is disclosed that generates a trip signal to operate a circuit breaker in case of a fault condition. A first module provides measurement and analysis of power parameters of the power line connecting the power equipment that is being protected, the protection being provided by generating a first trip signal for operating a circuit breaker connected in the power line. One or more second modules can boost performance of the protection relay by measurement and analysis of power parameters-to generate a second trip signal for operating a circuit breaker connected in the power line. The first trip signal and the second trip signal are logically combined to generate a trip signal that operates the circuit breaker.

摘要： A circuit breaker and method for interrupting the flow of electric current in a line includes connecting separable contacts to a conductor in the circuit. An actuating device, actuated by an activating signal, is connected to the separable contacts to effect separation of the contacts wherein the flow of electric current in the circuit is interrupted. A current sensor, such as an iron core current transformer, senses the current in the circuit to provide a first sinusoidal signal. A bridge rectifier is connected to the current sensor wherein the first sinusoidal signal is converted to a rectified signal and power is derived from the rectified signal. An interface circuit connected to the rectifying network converts the rectified signal into a second sinusoidal signal for providing the activating signal to the actuating device at a predetermined magnitude of the first sinusoidal signal. The interface circuit includes generating a sign bit indicative of the polarity of the first sinusoidal signal. A switch, such as a complimentary metal-oxide silicon (CMOS) switch, generates a positive half-wave rectified signal and a negative half-wave rectified signal from the rectified signal and the sign bit. The negative half-wave rectified signal is inverted and the positive half-wave rectified signal and the inverted negative half-wave rectified signal are summed and level shifted relative to the magnitude of the first sinusoidal signal to generate a second sinusoidal signal in phase with the first sinusoidal signal.

摘要： A current sensor has a closed loop magnetic flux concentrating ferromagnetic core with a gap and a central aperture for receiving a conductor. A Hall generator is positioned in the gap and a secondary winding is positioned on a portion of the core. Current flow in the conductor creates magnetic flux in the core which energizes the secondary winding to provide a power output. Magnetic flux concentrated in the gap causes the Hall generator to output a sensing signal that is proportional to the magnetic flux which is proportional to the current flow in the conductor. The single core is used to simultaneously produce a sensing signal proportional to alternating or direct current flow in the conductor.
