摘要： Methods and systems for detecting a falling power line in a power transmission or distribution system are described. Electrical measurements at various points in the power distribution system are used to detect changes in a power line indicating that the conductor has broken or become disconnected. Upon detection, control mechanisms are used to deenergize the conductor while the conductor is falling and/or before it contacts the ground.

摘要： Improved motor starters and/or overload electronics are presented for industrial automation systems, HVAC systems, pumping systems, and/or similar implementations. Protective devices can be configured to offer substantially automatic control and/or protection for motors without first being manually calibrated, or properly calibrated, for the motor. An overload, motor starter, and/or other motor protection and/or control device can accommodate substantially universal voltage input, true power characteristic sensing for status output/annunciation, integrated damper control, and substantially automated protection and/or trip point selection and/or protective parameter calculation and implementation with reference to startup values and/or system parameters such as full load amperage (FLA), motor classification, motor horse power, monitored current, monitored voltage, and true power characteristics, including power factor values.

摘要： A method and a device for preventing overstabilization of longitudinal differential protections in case of internal faults on power lines, which may take place when a fault situation, which is indicated as an external fault, is in reality an internal fault. The invention comprises criteria which finally provide information as to whether the longitudinal differential protection is to enter into operation. The criteria comprise level and directional determination of the currents which are measured in the terminals of the power lines, checking whether these have the same direction, and so on.
