Note:
In ground fault location described in Section “2.5 Signal Tracing with Signal Receiver”, the band
pass filter is turned on so that signal receiver can bypass other interference signals and only sense the
strongest signal (10Hz) which is injected from the signal generator.
3.2.2 Oscilloscope
This is to measure the waveform of target circuit. Please click “Oscilloscope” in main menu, screen will
be like:
Fig 3.2.2
Screen introduction:
Frequency
: Means receiver frequency. It is defaulted as 10Hz.
Channel
: Channel 1 in blue indicates the waveform when BP filter is ON. Channel 2 in red indicates the
waveform when BP filter is OFF. Channel 3 in green indicates the waveform of synchronization
signal.
ms/div
: Indicates the time (ms) of each grid in horizontal axle. It is selectable for different view.
mA/div
: Indicates current value (mA) of each grid in vertical axle. It is also selectable.
3.2.3 System Setting
Click “System” in main menu, you will see the screen for system setting as below:
Fig 3.2.3
3.2.3.1 Frequency synchronization
This is to make the receiving frequency of signal receiver identical with output frequency from signal
generator. All BST-GFL31 units are defaulted as 10Hz output frequency and have been synchronized
well with signal receiver before delivery to our customers.
