Investigations of injuries and fires caused by electrical circuits and equipment can result in incorrect conclusions when grounding systems are neglected. The term ground is loosely used in electrical jargon as any zero reference point for voltage measurement. Power systems are usually grounded to the earth. Other electrical systems are sometimes grounded to the same earth through a low impedance circuit. Residential grounding systems are described and a simple method is proposed for the investigator's use in evaluating the grounding system for potential shock or equipment damage hazards.
当接地系统被忽视时，对由电路和设备引起的伤害及火灾的调查可能会得出错误结论。在电气术语中，“接地”一词被宽泛地用作电压测量的任何零参考点。电力系统通常接地至大地。其他电气系统有时通过低阻抗电路接地至同一大地。本文描述了住宅接地系统，并提出了一种简单方法供调查人员用于评估接地系统是否存在潜在触电或设备损坏危险。
