我(wo)國(guo)的(de)供電(dian)(dian)系(xi)統一(yi)般(ban)采用(yong)三相四(si)線(xian)(xian)(xian)制。中性線(xian)(xian)(xian)接地，這(zhe)是通向(xiang)居(ju)民房屋的(de)電(dian)(dian)線(xian)(xian)(xian)。一(yi)個(ge)是相線(xian)(xian)(xian)（火線(xian)(xian)(xian)），另一(yi)個(ge)是零(ling)線(xian)(xian)(xian)，與地球(qiu)處(chu)(chu)于(yu)同一(yi)位置。當人(ren)體(ti)接觸熱底板(ban)時，將導致電(dian)(dian)流(liu)流(liu)過人(ren)體(ti)并與地球(qiu)形成回路，從而有觸電(dian)(dian)的(de)危(wei)險(xian)。如果使(shi)用(yong)隔離變壓器(qi)，則(ze)將更加安全，因為(wei)通過磁場能量交換了初級和(he)(he)次級。沒有物理(li)硬連接。即(ji)使(shi)人(ren)體(ti)觸摸(mo)帶(dai)電(dian)(dian)的(de)物品(pin)，人(ren)體(ti)和(he)(he)大(da)地也會(hui)(hui)處(chu)(chu)于(yu)同一(yi)位置，帶(dai)電(dian)(dian)的(de)部分仍會(hui)(hui)處(chu)(chu)于(yu)電(dian)(dian)位低的(de)狀態，不(bu)會(hui)(hui)引(yin)起。
