Submenu Transformer settings
The Transformer settings submenu contains the following items:
1. Main current transformer
2. Induced current transformer
3. Voltage transformer
Under the item
Main current transformer
, the primary and secondary current, as well as
phase allocation must be specified.
Under the item
Induced current transformer
, the primary and secondary current of
the induced current transformer must be specified. These settings have to be made for
each cabinet individually! For operating an energy measuring module, the primary and
secondary voltages of the energy measuring model can still be set here.
Under the item Voltage transformer the primary and secondary current, as well as phase
allocation of the measuring voltage must be specified. The zero-point creator can also be
activated here.
The series transformer submenu contains the following items:
1. Primary current
2. Secondary current
3. Phase allocation of principal current
For the items
Primary current
and Secondary current, the respective parameter for the
current transformer must be given, e.g. transformer 1000/5A means a primary current of
1000A and a secondary current of 5A.
The input field ranges from 1A to 99.99 kA for a primary current and 1A or 5A for the
secondary current.
For the
Phase allocation of the series transformer
the phase must be specified that is
measured in the principal current, e.g. phase I = L1.
For a false polarity transformer connection the input can be given as phase I = -L1 (the
minus sign means k and l are exchanged).
5.13.3
The voltage transformer submenu contains the following items:
1. primary voltage
2. Secondary voltage
3. Phase allocation of measuring voltage
4. Zero-point creator
For the items
primary voltage and secondary voltage
, the respective parameter for the
voltage transformer must be given, e.g. transformer 10,000/100 V
