Surge Arrester
Surge Arrester - Safeguarding Equipment and Ensuring Power System Reliability
A surge arrester, also known as a high voltage surge arrester or lightning arrester, is an electrical device that safeguards equipment from high voltage surges and transients. Surge arresters are typically installed in power grids and other electrical systems, with various types available, such as polymer and porcelain surge arresters. Surge arrester fittings and accessories like disconnector, discharge counter, and on-line monitor are also available to enhance protection. Surge arresters function by employing a non-linear resistor and spark gap to conduct high voltage surges, diverting the surge energy into the ground and reducing the potential for equipment damage. Surge arresters play a critical role in ensuring the safety and reliability of power systems across residential, commercial, and light industrial applications.

The fuse elements used in most distribution cutouts are tin or silver alloy wires that melt when subjected to high enough current. Ampere ratings of fuse elements vary from 1 ampere to 200 amperes.
Standards
Up until the mid-1990s each manufacturer used their own dimensional standards for cutout design; by the late 1990s most cutouts were of an "interchangeable design". This design allows for the interchangeable use of cutout bodies and fuse holders manufactured by different vendors.

Products FAQ
Used on overhead transmission lines and taps to protect distribution transformers from current surges and overloads,An overcurrent caused by a fault in the transformer or user circuit can cause the fuse to melt and the switch mechanism to visibly open,Disconnect the transformer from the line. The device can also be opened manually by a utility line worker standing on the ground and using a long insulating rod called a “ground rod”.
