Why should one end of the current transformer be grounded?
The secondary winding of the current transformer and the voltage transformer should be grounded during operation to prevent the high voltage from being connected to the low voltage through the transformer after the transformer insulation is broken down, which will hurt the instrument and the operator, and ground the secondary point of the transformer. , it will not affect the normal operation of the equipment, but also ensure the safety of personnel and equipment.
In order to ensure safety, the secondary side of the current transformer must be grounded, and it plays a protective role when the secondary side of the current transformer is in danger of high voltage to ensure the safety of people and equipment.
