The description below applies for a system with a nominal frequency of
60 Hz but can be directly applicable to 50 Hz. SESRSYN (25) can be
set to use different phases, phase to ground or phase to phase. Use the
set voltages instead of what is indicated below.
Figure 62 shows the general test connection principle, which can be used during
testing. This description describes the test of the version intended for one bay.
Figure 63 shows the general test connection for a breaker-and-a-half diameter with
one-phase voltage connected to the line side.
