System Power Up
Item Description
1 Confirm all necessary primary equipment isolations
2 Confirm all necessary secondary equipment isolations (including trip
outputs)
3 Check fitment of RA30 optical sensors and cable condition
4 Check panel installation of the RA24 monitor
5 Check for correct case earthing
6 Check the RA24 is wired to the protection design schematic, connected
to a Substation LAN and confirm all IEC61850 configurations
7 Confirm Fail alarm relay is closed (Terminals 25 and 26)
8 Apply correct Auxiliary voltage to power up the RA24
9 Upon power up the relay enters a relay boot cycle, all the Leds will flash
once and then extinguish and then in turn sequentially illuminate 1 led at
a time until all Leds are illuminated – the sequence takes about 14 secs.
Observe that the green power LED remains illuminated solid after
the relay boot cycle.
10 Confirm Fail alarm relay is open (Terminals 25 and 26) and the
associated LED is extinguished
11 Using a web browser check RA24 configuration settings match
protection setting specifications
12 Confirm that the Arc Sensor fail alarm LED remains off and none of the
sensor LEDs are flashing (Refer Sensor Failure Trouble shooting if a
sensor fail is indicated)
