Voltage transformer

The phase to phase voltage (L-L) is indicated
on display of the UMG 96L as secondary and
primary voltage. The transformer ratio is calcu-
lated from the programmed primary and sec-
ondary voltage. In programming mode, the vol-
tage transformer settings are marked by the
symbol „

VT

“.

The standard version is preset by the manufac-
turer with a ratio of 400V/400V.

The

secondary voltage

is always indicated in

„V“. The corresponding symbol „V“ is

not

dis-

played.
The

primary voltage

is indicated in „V“ or „kV“.

The corresponding symbol is displayed in „V“
or „kV“.

Programming

In programming mode, please scroll to the vol-
tage transformer setting by pressing key 2.
Confirm selection with key 1.

The first digit of the primary voltage flashes and
can be changed by pressing key 2.
If key 1 is pressed again the next digit will be
selected and flashes.
If the entire digit flashes, you can move the
decimal point.
If no digit flashes anymore, you may shift to in-
dication and programming of the outputs by
pressing key 2.

Attention!

The program allows current and voltage
transformer ratio setting only, if the maxi-
mum phase power can reach up to
50.0MW and the sum power can reach a
maximum value of 150.0MW.
