Sifam Tinsley Omega Xmer User manual

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)!

Assembly
1. Ensure a safe work environment during assembly, maintenance and inspection operations. If necessary interrupt
the current supply of the primary conductor and take precautions against unintentional switching.
2.(i) For Split core CT : Open the current transformer and fix it on the primary conductor using the fixing clamps
(mounting material).
(ii) For Window type CT : Bar or cable primary insert through primary cable or bus bar & fix it using mounting screw
assembly.
P1: Direction of power supply
P2: Direction of power source
Attention: (i) Do not close the current transformer, high voltages may appear on the open secondary leads.
(ii) Check for cleanness of the cut surfaces of the split core
3. Connect the secondary wires of the current transformer with the measuring device (ampere meter, energy meter).
Pay attention to the installation guide of the measuring device.
4. Now fasten the current transformer, press until the lock engage.
5. If necessary, start the current supply again.
6. Check whether the current transformer is assembled correctly and the secondary leads are connected properly.
7. For split core CT, use “lock pin” supplied along with CT to protect accidental opening of CT, during in use.
