When the dry power transformer is in normal operation, the core must have a reliable grounding. If there is no grounding, the suspension voltage of the core to the ground will cause the core to intermittently break through the discharge, and the core is grounded to eliminate the possibility of forming the core suspension potential.
Because the dry distribution transformer generates electric and magnetic fields during operation, the iron core and the iron member are at different positions of the electric field and the magnetic field. Due to the electromagnetic induction relationship, there is a voltage difference between the iron core and the iron member, and this voltage may cause A discharge occurs between the iron core and the iron member, causing the transformer to malfunction
However, when the iron core is grounded at two or more points, the uneven potential between the iron cores will form a circulation between the grounding points, causing the multi-point grounding heating fault of the iron core.
Therefore, the dry distribution transformer does not allow multi-point grounding to have only one ground and only one point.
