6.19 Plotting a
magnetization curve
Since Sverker has an ammeter, voltmeter and
voltage output, it can be used to plot points on a
current transformer magnetization curve.
IMPORTANT! Be sure to comply with the
applicable safety regulations, and never
exceed any insulation voltage limits.
1.
Initial setting: OFF. Main knob at 0.
2.
The primary side of the current transformer
must be open, and the secondary side
must not be connected to any other circuit.
3.
Connect the Sverker voltage output to the
secondary side of the current transformer.
One side of this voltage output must be
connected via the Sverker ammeter input.
If a voltage higher than 250 V is needed,
proceed as instructed in section 6.11,
entitled ”Generating higher voltages”.
4.
Connect the Sverker voltmeter input to the
Sverker voltage output.
5.
Use the button marked A to transfer the
ammeter test point to the panel input used
for measurement in external circuits.
6.
Activate ON using the start switch.
7.
Turn the knob clockwise and read the
current and voltage for different points on
the curve.
8.
When the knee of the curve is reached,
slowly lower the voltage and set the start
switch to OFF.
