Installation precautions
 

Before installing the open current transformer,it must be connected to the electric meter (or other measuring device) twice to ensure that the secondary transformer is not open;

Place all open current transformers connected with secondary wires on site and wait for installation;

If the primary busbar on site is a cable ,lie installation can be performed; If the primary busbar is a copper bar, the live operation requires a relatively high level of proficiency for the operator and the requires good insulation protection measures;

When installing the transformer ,foreign objects such as impurities and dust should not fall into the cut surface of the iron core ,so as not to affect the performance of the transformer.
