21.2.5 Transformer input module (TRM)
21.2.5.1 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.
