           Abstract:
     DC Ground faults on battery operating DC Multi feeders are very difficult to find without the proper instrument for detection and location and training.

    The DC ground fault Analyzer GFAL-A and the DC ground fault locator GFAL-B instruments are making use of a very small  DC signal to analyze      
    and to locate the DC ground faults on power plants, substations, refineries and switchyards.
   

      Finding the DC ground faults on Power Plants, user remark:
   The Power Plants sometimes don't see the need to clear DC ground faults a plant operator said to us we burned-up a $40,000 pump due to DC faults on 2 systems.
   Also years back we have two DC faults and started a very large cooling tower circulating water pump, clearing the DC ground faults are usually an after thought.

   
The need for DC ground fault location training:
    
Even with the proper instruments to locate DC ground faults the lack of training how to use and how the DC distribution system is lay-out and the role of outside
    interferences affecting the test result could be hours of troubleshooting and frustration.
    Samco Engineering will provide you with the instrument a 70 pages booklet and a CD with a Power Point Presentation for such training.

               GFAL-A: Ground Fault Analyzer Instrument (Interrupter unit)  

    *     Create a track signal to locate the DC ground faults up to the point of failure

    *    Functionally test the DC alarm unit operation

    *    Test the DC Distribution System for spike faults and AC contamination 

    *    Help to find the value of the fault resistance from each polarity with respect to site ground. 

          See the User's Manual Section 8.0 – GFAL- A, Appendix B.

    *    Set up the basis for a ground fault predictive maintenance program

              GFAL-B: Ground Fault Tracker Instrument (tracking unit)

    *    Will trace and locate the DC ground faults on DC multi-feeder distribution system, up to the point of failure without service
          interruption

    *    Detect and process the signal produce by the interrupter with a magnetic sensor (unique design) that wrap around the conductors.

    *    Never have to open a circuit or a breaker to troubleshoot a DC distribution system

    *    Set up the basis for a ground fault predictive maintenance program

                 MSA: Magnetic Sensor Assembly (tracking sensor)

    *    The design of the sensor probe is unique, there are available in 2 sizes  

                GFAL-CD: Training  CD "Fundamentals of DC Ground Fault"
