VT RATIOS
The primary and secondary rating can be independently set foreach
set of VT inputs, for example the residual VT ratio can bedifferent to
that used for the phase voltages.
Voltage ranges
57 – 130V
220 – 480V
** By costomer order
Primary
0,1 – 100kV
step = 0.01kV
220 – 480V
step = 10V
Secondary
57 – 130V
step = 0.1V
220 – 480V
step = 10V
