Does the ammeter display
load currents for L1 only?
Is the ratio of current that L1 is using
between terminals 12 and 21 of the
source selector switch correct? Refer
to Figure 5-35 for the proper turn ratio
of the current transformer.
Is the amount of current that L1 is
using between terminals 11 and 21
of the source selector switch correct?
Refer to Figure 5-35 for the proper
turn ratio of the current transformer.
