  • Why substation equipment fails and why its wise to think

    Dec 30, 2019The safety of electrical equipment depends to a large extent on sound mechanical design. The majority of circuit breaker failures are mechanical rather than electrical in nature. Typical faults are loose joints leading to overheating or arcing and the existence of voids and contamination in insulation causing arcing and breakdown products.

  • Insulator (electricity) - Wikipedia

    Physics of conduction in solids. Electrical insulation is the absence of electrical conduction.Electronic band theory (a branch of physics) dictates that a charge flows if states are available into which electrons can be excited. This allows electrons to gain energy and thereby move through a conductor such as a metal.If no such states are available, the material is an insulator.
