*   Test for ground fault resistances in  multi-feeder distribution systems 

    *  Help to calculate the fault resistance in each polarity with respect to ground 

      *   Analyze and functional test the DC ground fault alarm unit

    *   Detect spikes and AC power contamination in battery distribution  systems 

    *   Will perform the function of a DC ground fault detector and indicator unit 

    *  Create a DC tracking signal for troubleshooting with the GFAL-B tracking unit

Performance

 *    Operate on 12 VDC to 250 VDC ungrounded DC systems 
 *     Variable load resistance selection for safety operation
 *     Plant operation remains uninterrupted during test

 *    Does not use or inject AC signals to operate

Typical users for the GFAL-A

    The DC ground fault analyzer GFAL-A is utilized in situations where a high degree of service reliability and safety from the multi-feeder 
    DC distribution system is required and desirable.
