7SA511 Line Protection Relay

Chapter 5

Table 5-1 lists the relay presettings, the optional settings and the setting ranges available for the rear port. Compare these presettings to the information on the completed worksheets and determine which settings you need to change to match your operating environment. After all settings have been verified or changed appropriately, follow the procedure described in section 5.3.4 to save the new settings.

Reference G of this manual, “Input/Output Functions,” identifies the relay annunciations that can be transmitted to and accessed from a substation control system.

5.5 Waveform Capture Settings

You can access and review the relay’s fault waveform data when your relay is configured for waveform capture, the waveform capture function is turned on, and the relay is operated using DIGSIsoftware. You can also indicate whether the waveform capture records will be sent to a PC connected to the front port or to a substation control system connected via the rear port. Waveform capture stores the voltage and phase current waveforms.

Table 5-2 lists the preset waveform capture settings and setting options. Compare these preset- tings to the information on the completed worksheets and determine which settings, if any, you need to change to match your operating environment.
