MRD-FD型发电机中性点电阻器柜为专用于发电厂发电机中性点采用高电阻接地的成套装置。发电机电压等级主要为6kv至20kv。当定子发生一点接地时，可限制接地电流在很小的数值，并有效抑制电弧接地暂态过电压。
MRD-FD series generator neutral resistance box is dedicatedly applied to integrated e in power station where the generator neutral grounding through high resistance. The mian grade of voltage is from 6KV to 20KV, when one point of stator grounds it could limit grounding current at a very low level and effectively suppress arc grounding transient overvoltage.
