Transformer input module TRM
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.
Ring lug or compression type connectors can be
ordered.
High impedance resistor unit
The high impedance resistor unit, with resistors for
pick-up value setting and a voltage dependent resistor,
is available in a single phase unit and a three phase unit.
Both are mounted on a 1/1 19 inch apparatus plate with
compression type terminals.
