Current transformer circuit connection method
Aug 15, 2022| 1. The current transformer cannot allow the secondary lead
The current transformer manufacturer has repeatedly warned everyone not to go to the secondary lead when the current transformer is installed, otherwise it will cause very serious adverse effects. It will cause the transformer core of the current transformer to accumulate a lot of heat, and even damage the current transformer. The second is that the secondary lead will lead to an increase in the number of winding electromagnetic coils of the current transformer electromagnetic coil, and its magnetic induction working voltage will be much higher, which will cause thermal breakdown of machinery and equipment and harm the personal safety of workers.
2. The secondary side of the high voltage current transformer must have one end which must be grounded.
Since the primary side of the high-voltage current transformer is in a high-voltage state, at this time, if the middle of the primary and secondary electromagnetic coils can be reduced in dielectric strength, the equipment will be thermally broken down by the high-voltage heat. At this time, the high-voltage After the primary side of the current transformer is grounded, the high voltage will be guided into the ground, which can ensure the safety factor of the machinery and equipment and the safety of the workers.
3. The accurate measurement and maintenance port number of the current transformer cannot be wired incorrectly
Because the precise measurement and maintenance port numbers are different according to the thickness of the transformer core design, if the connection is wrong, the information accurately measured by the current transformer during the whole process of normal operation will be unreliable.
