on BESANTEK’s years field experience, 10Hz output frequency will fit most DC systems for fast
location of earth fault. Generally it is no need to change.
If you have particular DC system that needs other output frequency, please first change the setting
in Section “3.1.2 Parameter Setting”
. And also do frequency synchronization as per steps in
Section “3.2.3.1 Frequency synchronization”.
2.4.3 Output Signal to Circuit for Fault Location
After above adjustment, click Next to continue. You will see the screen like Fig 2.4.3.1 with output
voltage, current, grounding resistance and waveform. Defaulted waveform is displayed as “Continued”.
You could use arrow key to change the view as “Discontinue” which will have 1 second interval. Different
ways of display is illustrated as diagram in Fig 2.4.3.2 and Fig 2.4.3.3.
NOTE:
For ground fault location, please set signal display as “Continue”.

1000V on the right side of screen (Fig 2.4.3.1) indicates the output voltage. Numbers on the right column
(e.g.4 and 0 in Fig 2.4.3.1) are for BESANTEK’s R&D purpose, users can neglect it. All these numbers in
the screenshots are for reference only; they are different in different circuits.
Signal auto adjustment:
After adjustment for output signal, the output voltage may still be automatically increased or decreased
to a proper value in the screen like Fig 2.4.3.1.
This auto adjustment will help users gain better signal for ground fault location. Meanwhile, it will prevent
the signal from being too strong to damage the DC system.
