dry-type cast resin transformers have been shown to reduce this risk. Since they do not contain petroleum, they greatly reduce the risk of fire. They are also rated F1 in terms of fire protection standards. This means they will not cause a fire under short circuit conditions and are inherently fire resistant.

The core of a power transformer must be reliably grounded for normal operation. If there is no grounding, the suspension voltage of the iron core to the ground will cause the intermittent breakdown and discharge of the iron core to the ground, and the possibility of the formation of the suspension potential of the iron core will be eliminated after the grounding of the iron core at one point. However, when the core is grounded at more than two points, the uneven potential between the core will form a circulation between the ground points, and lead to the core multi-point grounding heating fault.

A transformer is a static electrical appliance that converts ac energy of one voltage class into AC energy of another voltage class of the same frequency by means of electromagnetic induction between coils. The transformer works on the principle of electromagnetic induction and consists of two windings that are insulated from each other and have unequal turns.
