In the past 120 years, electricity has become the overarching energy source in our everyday life. Its applications have improved our comfort and safety, multiplying the means of entertaining and communicating.
However, domestic electricity can be dangerous. Specifically, the safety of older electrical installations is a concern in the countries of the European Union, given the low renovation rate of dwellings and their electrical installations. At the same time, the uses of domestic electricity continues to diversify and develop, progressively posing increasingly important challenges in terms of quality and safety of electrical energy used in households.
The safety deficiencies of obsolete electrical installations generally result from the aging of their components, the lack of maintenance and inappropriate usage. The dangers they represent are also clearly identified. The risks of electrification and electrocution are well known, but fires of electrical origin and their consequences are the most worrying.
