摘要： Apparatus protected against ground faults for monitoring the ground connection between a grounded power source and a mobile machine provided with multi-phase power through a multi-conductor trailing cable has a star arrangement of impedances connected to the phase conductors at the power source and a like arrangement connected at the machine, the junctions of which are connected to the ground conductor at each end, through a silicon-controlled rectifier device which is paralleled by a monitoring impedance. At least one impedance of one of the star arrangement of impedances is adjusted to provide a low monitoring voltage which circulates a current through the ground conductor and monitoring impedance. The voltage across the latter actuates monitoring means. The silicon-controlled rectifier is adjusted to conduct when the voltage across it rises above the monitoring level. The monitoring current may be alternating current, or direct current obtained from a rectifier in circuit with the ground conductor.

摘要： A grid resistor has a plurality of identical resistor support frames each defining a plane. The frames are stacked in alignment to form a hexahedron structure with levels of frames. Plates on the outer face of the hexahedron structure support the frames tightly against each other to maintain the hexahedron structure. Within each frame there is at least one ribbon of resistance material which is fanfolded providing a plurality of equally spaced, parallel, uniform linear lengths connected by U-shaped folds. The U-shaped folds have studs at the outer tips of the folds which engage holes in the resistor support frames. Bus bars selectively couple the resistors in each level to a pair of output terminals.

摘要： I disclose an electrical resistor having a plurality of elongated resistor elements arranged in a closely spaced generally parallel array and connected electrically for electrical loading purposes. A supporting and insulating arrangement for the elements is disposed intermediate the ends of the elements. The arrangement has a plurality of metallic supporting straps and insulating members detachably joined.
