Utilities invest signi cant time and nances into substation maintenance in order to anticipate failures or accelerated aging in power equipment. Current practices include regular insulation condition tests for switching devices, reactors, power transformers, and so on. Many of the indicators of equipment condition are imprecise, unreliable and costly to obtain on a regular basis. To achieve use...

External Thermal Insulation Composite Systems (ETICS) are constructive solutions widely used to increase the thermal insulation in new and retrofitted buildings. However, these systems can present several anomalies due their constant exposure weathering agents anthropic factors. Water is generally major cause of degradation. Thus, application water-repellent products minimize appearance durabil...
