Methods and apparatus for mitigation of damage of power line assets from traveling electrical arcs
First Claim
1. A system configured to protect a power distribution network and devices mounted on the power distribution network from damage caused by a traveling arc, comprising:
- a line monitoring device mounted to a conductor of the power distribution network;
a line mount mounted on the conductor adjacent to the line monitoring device and not attached to the line monitoring device; and
a conductive shield attached to the line mount without contacting the conductor and being substantially perpendicular to the conductor, the conductive shield comprising a sacrificial conductive material configured to be consumed by the traveling arc when the traveling arc interacts with the conductive shield.

Abstract
A power distribution monitoring system is provided that can include a number of features. The system can include a plurality of power line sensing devices configured to attach to individual conductors on a power grid distribution network. The sensing devices can be configured to measure and monitor, among other things, current and electric-field on the conductors. The system can further include one or more arc shields positioned near the sensing devices and configured to prevent damage to the conductor or sensing device in the event of a traveling arc. Methods of installing and protecting the system are also discussed.
