Problem Definition
Every year, millions of dollars are spent repairing power line infrastructure and restoring power when adverse weather strikes. Power lines and utility poles can be broken due to high winds, ice buildup, or other severe weather conditions. There needs to be a way to protect the power lines and the utility poles from breaking under these conditions.

Background
The grid defender is the proposed solution that adds security to the power infrastructure. Grid Defender (GD) is a utility pole support system invented and patented by Dennis Bell. This design allows the cross arms of utility poles that support power lines to be lowered to the ground if there is a dangerous load on the poles or lines. When the cross arm is lowered, the flow of electricity is automatically cut within the sector. Once the storm or danger has passed, a single lineman can raise the cross arms back into place with the use of a small motor.

Deliverables
By the end of the year we plan to build and test a full-scale 5 pole prototype on campus. This prototype will showcase the lines dropping under a specific weight limit at the desired descent rate, as well as the method of resetting the entire system.

Specifications
The system is set to release once a 4000 pound threshold is reached, and descend at a rate of 8 ft/sec. Once the system starts dropping, a signal will be sent to the breakers on the ends of the GD sector to cut power in the lines. At the same time, a GPS node that is on each pole will send a signal to control indicating each dropped pole's location so a technician can easily locate and reset the downed poles.

Selection
The team has decided to go with a class 4, 35 foot pole, with the help of the inventor. Most mechanical components will be built with corrosive resistant materials as the system will have to withstain weather effects.

Implementation & Testing
In order to test the system 5 poles will be mounted on campus by Avista. We will then overload the system with a winch or concrete block to test the breakaway and decent of the system.
