Maintaining Installations In Hazardous Areas
Flameproof enclosure (Ex d) and intrinsic safety (Ex i) are very common equipment protection methods in Process Automation. One reason to use Ex d is the amount of energy which could not be provided via Ex i. This disadvantage has gone with the introduction of intrinsically safe, dynamic methods of arc prevention such as DART or Power-i. This white paper shows that when using intrinsic safety, installation, maintenance and inspection costs will be reduced.
This paper addresses decision makers and professionals responsible for automation systems in hazardous areas. A good understanding of the principles of explosion protection is required.
