The role of drop-out fuses10kV equipment can be installed on the high-voltage side of the transformer on the pole, where the transformer and capacitor are connected to the line. The drop-out fuse can effectively protect the circuit from overload and short-circuit. At the same time, it can also be installed at the end of a long line or on a branch line, which can provide extended protection for areas that cannot be protected by relays.

Fuse selection The selection of the fuse should ensure that the distribution transformer internal or the high and low voltage outlet pipe can be quickly fused when there is a short circuit. In practice, the following principles are often used for selection; if the capacity of the distribution transformer is below 160KV, the fuse should be 2-2% of the rated current of the transformer.
