Transformer
6 - 3
TRRatio (per Tap)
Use the
TRRatio
test card to measure a power transformer’s ratio by injecting
AC voltage with up to 2kV from
AC OUTPUT
into the transformer’s primary side
CPC 100
measures both the voltage it applies to
AC OUTPUT
and the
transformer’s secondary voltage at
V1 AC
. From these values it calculates the
ratio and its deviation from the nominal ratio in percent.
In addition, the exciting current is measured as well as the phase angles of both
the secondary voltage and the exciting current.
Furthermore, the
TRRatio
test card is used to measure a power transformer’s
ratio for each single tap changer position (see Figure 4).
