Introduction: Over the years UK electricity transmission business has suffered a number of disruptive failures to hollow-core porcelain-clad equipment from the thermal shock energy generated by an internal electrical fault, which has seen porcelain fragments projected over a wide blast area. This phenomenon raises concerns within the business of its management of the health, safety and welfare to both its employees and general public from these risks. The aim of the project is to investigate ballistic screening options in terms of safety and cost effectiveness.

Objectives: To produce a ballistic screen that can minimise damage from potential failures.
