VT Burden
Use the
VTBurden
test card to measure a voltage transformer’s secondary
burden with voltage injection on the VT’s secondary side with up to 130V from
AC OUTPUT
.
To do so, open the circuit as shown in Figure 4 and inject the AC voltage from
CPC 100
130V AC
output into the burden.
Input
IAC
measures the current that flows into the burden, and input
V1AC
the
voltage at the burden.
From these measurements, the burden (in VA) and the power factor cos
ϕ
are
calculated.
