22.2.5.1 Introduction
The transformer input module is used to galvanically separate and adapt the secondary currents
and voltages generated by the measuring transformers. The module has twelve inputs in different
combinations of currents and voltage inputs. Either protection class or metering class CT inputs
are available.
Alternative connectors of Ring lug or Compression type can be ordered.
22.2.5.2 Design
The transformer module has 12 input transformers. There are several versions of the module, each
with a different combination of voltage and current input transformers.
Basic versions:
