Section 10
Testing functionality by secondary injection
Testing the voltage selection for 1 1/2 CB arrangements
At test of the SESRSYN function for a 1½ CB diameter the following alternative voltage inputs
can be used for the three SESRSYN (SESRSYN 1, SESRSYN 2, SESRSYN 3) functions. These three
SESRSYN functions can either be in one, two or three different IEDs. Table
scenario when SESRSYN 1, SESRSYN 2 and SESRSYN 3 all are in the same IED. If SESRSYN 3 is in
another IED, WA1 will be considered as WA2 and LINE2 as LINE1. The voltage is selected by
activation of different inputs in the voltage selection logic as shown in table
Table 33:
