摘要： An apparatus includes a first terminal configured to be coupled to a substation around mat for a substation and a second terminal configured to be coupled to a safety around mat for a piece of electrical equipment powered by the substation. The system further includes at least one voltage-dependent resistance device, such as at least one metal oxide varistor (MOV) configured to be coupled between the first and second terminals. At least one circuit interruption device, such as a fuse and/or a disconnect switch may be coupled in series with the at least one voltage-dependent resistance device.

摘要： A directional flow current transducer is used as a transient stray voltage detector including a first transducer providing an output signal indicating the magnitude of stray current carried by a new grounding wire, and a second, separate transducer providing an output signal indicating the direction of the stray voltage (for either direct and/or alternating stray voltages). The new grounding wire might be between an equi-potential plane of a concrete platform for watering livestock and a grounding bus bar for grounding the service bond of the main electrical service panel, at a significant distance from the watering platform. The output of the directional flow current transducer is recorded, stored and analyzed as a function of time. Preferably by allowing comparison with the output of a second directional flow current transducer, the system allows transient, directional and locational stray voltage/stray current problems to be better identified, understood and addressed.

摘要： The present invention relates to an arc eliminator, and more particularly, to an arc eliminator with an earth contact. An arc eliminator comprises: a housing; an extinguisher installed on the housing; and an earth contact that is installed on the housing and protrudes out from the housing in such a way as to be connected to the ground bus bar provided inside a distribution board when the extinguisher is moved to a first position where the extinguisher is connected to a fixed bus bar provided inside the distribution board, and to be disconnected from the ground bus bar when the extinguisher is moved to a second position where the extinguisher is disconnected from the fixed bus bar.
