SE-330系列是一款先进的接地故障和中性点接地电阻器监控继电器，符合2018加拿大电气规范第I部分（CE规范）10-302条规则。该继电器可以测量中性线电流、中性点接地电压以及中性点接地电阻。 它可持续监控中性点接地路径，以验证中性点接地电阻器（NGR）的完整性，及其是否未旁通或短路。 开路NER会导致电流传感型接地故障保护失效，而且可能会导致操作人员误以为系统运行正常。 NGR短路会造成超过预期的接地故障电流。 当配置符合标准的保护装置且该装置处于活跃状态时，唯一的LED闪烁代码可为工厂安全团队和检查人员提供外部确认。

SE-330适合采用低电阻或高电阻接地的低电压和中等电压的变压器和发电机，可用于加工、制造、化工、纸浆和造纸、石油以及水处理设施。 35kV以上的应用，请使用SE-330HV。 需要遵守澳大利亚/新西兰AS/NZS 2081标准的应用，请使用SE-330AU。

如要全面设置SE-330，必须连接至运行SE-MON330 v4.10或更高版本软件的PC。 网络通信有三种可用的协议选项:

  • IEC 61850 - 通过双RJ45、SC光纤和RJ45或双SC光纤接口
  • Modbus TCP和Ethernet/IP - 通过双RJ45、SC光纤和RJ45或双SC光纤接口
  • DeviceNet - 通过CAN接口
对于无法使用现有的开关设备或需要单独的控制面板的应用场合，也可以提供采用NEMA 4X封装的SE-330。 NGRM-ENC系列可提供多个选项以满足客户的特定应用需求，包括表面安装型或门上安装型SE-330。

电阻监控
SE-330结合电阻、电流和电压的测量值，持续确定NGR完好无损。 无论是否存在接地故障，都能检测到开路或短路的电阻器。 感测电阻器与系统电压相匹配，用于监控高达72kV系统上的NGR。

接地故障监控
SE-330使用适合应用的电流互感器来可靠地检测小到100mA的接地故障电流。 离散傅里叶变换（DFT）滤波可确保不会出现由可调速驱动器的谐波噪音引起的误跳闸。 如果电阻器开路，随后发生接地故障，SE-330将通过电压测量检测故障，而其他仅感测电流的继电器将不起作用。

脉冲接地故障定位
SE-330能够控制脉冲接触器，该接触器用于切换兼容脉冲的NGR封装中的NGR电阻。 由此产生的接地故障电流不同于充电电流和噪音，只会出现在接地故障的上游，即使不隔离馈线或中断负载，也能快速轻松地定位故障。
