1.2 SE-330 NGR MONITORING The SE-330 is a microprocessor-based neutral-grounding-resistor monitor that detects NGR failures and ground faults in resistance-grounded systems. The SE-330 measures NGR resistance, NGR current, and transformer or generator neutral-to-ground voltage. The components required to monitor an NGR are an SE-330, a
Series: SE-330 - Littelfuse
The SE-330 series is an advanced ground-fault and neutral-grounding-resistor monitoring relay that is compliant with Rule 10-302 of the 2018 Canadian Electrical Code Part I (CE Code). It measures neutral current, neutral-to-ground voltage, and neutral-to-ground resistance.

SE-330 measures NGR resistance, NGR current, and transformer or generator neutral-to-ground voltage. The components required to monitor an NGR are an SE-330, an ER-series sensing resistor, and a current transformer (CT). The SE-330 continuously measures NGR resistance in an unfaulted system, and it will trip on resistor fault if

SE-330 手册 中性点接地电阻监视器 - 百度文库
SE-330测量NGR电阻、NGR电流、以及变压器或发电机中性点接地电压。 监视NGR的设备为 一台SE-330、一个 ER-系列感应电阻和一台电流互感器 (CT)。 SE-330连续测量一个正常系统的NGR电阻，如果NGR电阻与其标定电阻值不同，它将进行电阻故障跳 闸。 当发生接地故障时，在中性点有电压，如果NGR还正常的话，NGR电流将流通。 如果在超过设 定的GF TRIP TIME（接地故障跳闸时间）内，故障电流超过设定的GF TRIP LEVEL（接地故障跳闸 电平），SE-330 …
