Omicron CP TD1 - Measuring CL on Two-Winding Transformers

OMICRON 43
Power transformers
For the measurement of C
L
the setup has to be changed. The HV output has to be connected to the LV
side and IN A to the HV side (see Figure 5-4 blow).

C
HL
and C
L
With this setup 3 configurations are available as well (see Table 5-2 below). As C
HL
has been measured
before, usually only C
L
is measured in this second measurement.
