Environmental influence on the safety and reliability of electrical and communication systems

Electrical systems may fail due to change in the properties of constituent materials under environmental influence. This failure may engender catastrophic events, such as material damage, environmental disasters or loss of human lives. For example, ships, as complex systems, are exposed to the aggressive nature of the marine environment. The influence of dominant factors on dielectric properties is analyzed in this paper through the relative dielectric constant, and the refractive index. Parameter changes are shown to alter the value of the constant by numerical examples. These different values can result in fatal system failures. Taking into account these facts, the influence of material on the electrical system is illustrated to make the reliability calculation more complex. The results were negative, as shown in the Calculation and results section.
