Below Zero °C Ice Destroys Power lines
In some areas, when the temperature drops below zero, the ice accumulates on high-voltage cables increasing the weight of the cables and amplifies the oscillation effect caused by the wind, leading to the breaking of the pylons.
TRIZ suggests to understand the system and find useful or harmful fields or substances from the «problem» perspective
It’s time to Apply TRIZ Algorithm
•Choose the Harmful functions to eliminate or the useful effects to improve
•Follow the Algorithm and apply the principles
•Generate specific Ideas for the problem
The result
In the example, one of the solutions identified by TRIZ is to stabilize or increase the cable temperature to avoid or melt the ice.
Following TRIZ this principle it’s found: “Phase transition using materials with the Curie Point equal to 0°C“ *
* Curie Point is the temperature at which a material’s magnetic properties disappears. When electric power is applied, these materials generate heat due to electromagnetic effets when tehmerature is below zero, preventing ice formation. When the temperature rises, the effect disappears, ensuring the function is active only when needed
