Note that all current and voltages are reported in primary system quantities.
e) Check the communication and data retrieval performance by issuing the SEL-2020
STATUS command. The SEL-2020 responds with SEL-2020 general information,
optional equipment information, and communication performance, including a listing of
ports with their respective communication status, communication success rate, and data-
base delays. In this example, the SEL-251 Relay is connected to the SEL-2020’s Port 1,
which is shown with active status and 100% communication success rate. If the relay is
disconnected or turned off, the status changes to inactive. If database delays were
encountered on this port, the specific region, or regions, affected would be listed under
database delays. If these delays were a problem, you could adjust the data collection
period or times to prevent overrunning data that can cause database delays.
