接地電阻測試儀常用知識解答

1． 定義
地電流：在大地或在接地極中流過的電流。
接地導體：指構成地的導體，該導體將設備、電氣器件、布線系統、或其他導體（通常指中性線）與接地極連接。
接地極：構成地的一種導體。
接地連接：用來構成地的連接，系由接地導體、接地極和圍繞接地極的大地（土壤）或代替大地的導電體組成。
接地網：由埋在地中的互相連接的裸導體構成的一組接地極，用以為電氣設備和金屬結構提供共同地。
接地系統：在規定區域內由所有互相連接的多個接地連接組成的系統。
接地極地電阻：接地極與電位為零的遠方接地極之間的歐姆律電阻。（注：所謂遠方是指一段距離，在此距離下，兩個接地極互阻基本為零。）
接地極互阻：指以歐姆為單位表示的，一個接地極1A直流電流
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
