Ground-fault problems are not limited to self-limiting cables

The use of a ground-fault equipment protection device would detected the fault current in the early stages and tripped the circuit when there is problem with the system. It provides evidence that ground-fault problems are not limited to self-limiting cables. Read more

Simplification Principle of Inherently Safer Design

Simplification means designing to eliminate unnecessary complexity, reducing the opportunities for error and mis-operation. A simpler plant is generally safer and more cost effective than a complex one. Read more

Moderation Principle of Inherently Safer Design

Moderation means using materials under less hazardous conditions, also called attenuation. Moderation of conditions can be accomplished by strategies which are either physical (lower temperatures, dilution) or chemical (development of a reaction chemistry which operates at less severe conditions).
