Non-earthed IT (Isolated Terra) power systems represent a deliberate design choice in heavy industrial applications—particularly in port machinery, mining equipment, and large festoon crane systems—where operational continuity is paramount. Unlike the grounded (TN or TT) systems standard in most commercial buildings, IT systems are engineered to tolerate single-phase earth faults without automatic shutdown. 非接地IT(隔离接地)电源系统代表了重工业应用中的一个刻意设计选择——特别是在港口机械、采矿设备和大型自动供电起重机系统中——其中运营连续性至关重要。与大多数商业建筑中标准的接地(TN或TT)系统不同，IT系统经过设计，可以在单相接地故障时继续运行而不需要自动断电。
