    任何电网设备都存在对地绝缘电阻和接地电流监控的必要性，为保证其安全运行，这种监控必须是连续不断或经常的，并要在接地电流大于允许值时，就能发出警报以提醒操作者妥善处理由于绝缘电阻下降而可能引发的事故。
   All power network equipment have the necessity to monitor the ground insulation resistance ａnd the ground current to ensure the running safely. This monitoring must be continuously or frequently, ａnd when the ground current is higher than allowable, it can give alarms to remind the operator to deal with the fault to avoid the possible accident due to insulation resistance decreased.
   SD-0.66-L型剩余(零序)电流互感器,与本公司专用电流继电器配套使用。该产品为户内电缆式，具有结构新、体积小、精度高、外形美观等特点。主要适用于TT或TN系统中ABCN同时穿越ZCT时使用
    SD-0.66-L type residual (zero sequence) current transformer is used together with our specified current protection relay. It is designed for in-house cable entry ａnd has the features of modern construction, small size, high precision ａnd fine appearance.
It is mainly applied for ABCN to go through the ZCT simultaneously in the TT ａnd TN system.

    由SD-ZLD系列剩余电流动作保护继电器和零序电流互感器组合，构成接地故障保护装置，适用于TN、TT和IT电网系统。通过接地电流互感器检测出接地零序漏电电流，经剩余电流动作保护继电器与设定值的比较和判别，及时发出动作信号，接通或断开报警回路，以避免事故的扩大，从而保证人员及设备的安全。
   The combination of SD-ZLD series residual current transformer ａnd zero sequence current protection relay forms ground fault protection device, it applies to TN,TT ａnd IT power system. Via the ground current transformer to detect the ground leak current, the current protection relay compares the sensed current with the setting value ａnd issues operating signal timely, make or break the alarm circuit, to avoid the accident, ensure the safety of personnel ａnd equipment.
