接地电阻测试仪常用知识解答

1． 定义
地电流：在大地或在接地极中流过的电流。
接地导体：指构成地的导体，该导体将设备、电气器件、布线系统、或其他导体（通常指中性线）与接地极连接。
接地极：构成地的一种导体。
接地连接：用来构成地的连接，系由接地导体、接地极和围绕接地极的大地（土壤）或代替大地的导电体组成。
接地网：由埋在地中的互相连接的裸导体构成的一组接地极，用以为电气设备和金属结构提供共同地。
接地系统：在规定区域内由所有互相连接的多个接地连接组成的系统。
接地极地电阻：接地极与电位为零的远方接地极之间的欧姆律电阻。（注：所谓远方是指一段距离，在此距离下，两个接地极互阻基本为零。）
接地极互阻：指以欧姆为单位表示的，一个接地极1A直流电流
Ground Resistance Tester common knowledge to answer

1. Definition
Ground Current: earth or grounding in the stream's current.
Conductor: that form to the conductor, the conductor will be equipment, electrical devices, wiring systems, or other conductor (usually neutral) and grounding connections.
Ground: composition to a conductor.
Ground connection: used to form ground connections, by the grounding conductor, grounding, and the earth around the grounding (soil) or to replace the composition of the earth conductor.
Grounding: buried in the ground in the interconnected form of a bare conductor grounding, with electrical equipment and metal structures that provide a common ground.
Grounding system: the specified area of all interconnected systems composed of multiple ground connections.
Polar Grounding Resistance: Ground zero of the distance and the potential between the grounding resistance Ohm law. (Note: the so-called distance is a distance, this distance, the two mutual grounding resistance at zero.)
Mutual Ground resistance: refers to the ohm as the unit, and a 1A DC Grounding
