■Displaying Waveform
The software allows you to analyze waveforms from the instantaneous value data of voltage
and current recorded by protective relays when faults or disturbances occur in power systems.
This part describes displaying waveforms when they are opened in the PC control software.
《Operating Procedure》
① Opening a waveform data in the PC control software displays the fault time
information and the waveforms.
･ 3 cursors are displayed at the following points in the channel in which the voltage drop ratio is the largest.
Fault detection point Cursor 0 (Green)
Lowest voltage point Cursor 1 (Red)
Restoration from fault point Cursor 2 (Yellow)
･ You can previously select whether the fault time is calculated automatically when a waveform data is
displayed.
