IS200EGDMH1AFF GE 励磁场接地检测模块
IS200EGDMH1A型号为励磁场接地检测模块，即EGDM的功能缩写。在安装过程中，该模块将安装在励磁电源背板机架上，并将靠近EPSM模块。该模块工作在一个单冗余系统上，单冗余系统需要一个EGDM模块，冗余系统需要三个EGDM模块。IS200EGDMH1A与EXAM模块一起使用，这两个模块一起工作，以确定直流或交流侧任何点的现场接地泄漏的潜力。
当EGDM模块和DSPX模块通过光纤连接时，EGDM模块将已经使用的电压通过光纤发送到DSPX模块;在此过程发生后，电压将被检查，并由DSPX附加警报。EGDM模块面板上有三个LED指示灯。IS200EGDMH1A模块有三个指示灯，分别是电源指示灯、主用指示灯和可选主用指示灯。
识别该模块的最佳方法之一是通过直接打印在板上的字母数字目录编号，但在面板底部也有一个小板，指示模块是什么。
I200EGDMH1A不是高故障率模块，因此需要很少的备件和维修。也就是说，由于冗余系统使用三个IS200EGDMH1A，因此至少保留一个备用系统是至关重要的。

IS200EGDMH1A is an exciting field grounding detection module, that is, the functional abbreviation of EGDM. During installation, the module will be mounted on the excitation power backplane rack and will be close to the EPSM module. The module works on a single redundant system that requires one EGDM module and a redundant system that requires three EGDM modules. The IS200EGDMH1A is used with the EXAM module, and the two modules work together to determine the potential for field ground leakage at any point on the DC or AC side.
When the EGDM module and DSPX module are connected through optical fibers, the EGDM module sends the used voltage to the DSPX module through optical fibers. After this process has occurred, the voltage will be checked and an additional alarm will be added by DSPX. There are three LED indicators on the EGDM module panel. The IS200EGDMH1A module has three indicators: power indicator, active indicator, and optional active indicator.
One of the best ways to identify the module is through the alphanumeric catalog number printed directly on the board, but there is also a small board at the bottom of the panel that indicates what the module is.
The IS200EGDMH1A is not a high failure rate module and therefore requires few spare parts and maintenance. That said, since the redundant system uses three IS200EGDMH1A, it is critical to keep at least one backup system.
