with test results
Navigate to the parameter fields, and enter the values according to your test
requirements:
Note:
The transformer’s core is magnetized after the measurement.
Demagnetization can be done using the
CT Excitation
test card (see ”CT
Excitation (Kneepoint)” on page 15 of this chapter.
Range:
output range (Use the
6A DC
output for measuring CTs.)
Itest:
nominal test current
R min:
calculated minimum winding resistance value (display only).
Depends on the value of the nominal test current and the
measuring range:
– 400A DC: Rmin = 0.2mV / Itest
– 6A DC: Rmin = 0.2mV / Itest
– V DC (2-wire): Rmin = 0.2
Ω
R max:
calculated maximum winding resistance value (display only).
Depends on the value of the nominal test current and the
measuring range:
– 400A DC: Rmax = 5V / Itest.
– 6A DC: Rmax = 10V / Itest.
– V DC (2-wire): Rmax = 20k
Ω
