TRANSFORMER SERIES : Omega Xmer,
Operating Manual
Indication
Before initial operation we ask you to pay full attention to these assembling instructions in order to guarantee the
reliability and to ensure the performance of the device.
Functional description
Current transformers of the model range Omega are inductive single conductor-current transformers operating
according to the transformer principle. Due to the applicated measuring principle, current transformers of this type
may only be installed in alternating current (AC) networks.
Safety instructions
In order to avoid personal and material damage the following assembling steps
must by performed only by authorised, qualified and trained personnel.
If the secondary circuit is operated without a burden/load (open) high voltages
may appear. These voltage values are dangerous for persons as well as for the
functional reliability of the current transformer.
It is forbidden to operate the current transformer without a secondary
circuit (open)!
