Intrinsically safe energy storage power supply

What are the advantages of intrinsic safety?

The major advantage of intrinsic safety is that it provides a solution to all the problems of hazardous areas (for equipment requiring limited power) and is the only technique which meets this criterion. The IS technique is accepted throughout the world.

What is intrinsically safe equipment?

Intrinsically safe equipment refers to portable apparatus used in isolation, such as torches and radios. This analysis does not apply to these types of apparatus.

What is the main advantage of intrinsic safety in dusty environments?

To summarise, intrinsic safety is the preferred technique for instrumentation where dust is the hazard because the inherent safety of intrinsic safety gives the greatest assurance of safety and removes concern over overheating of equipment and cables. Live maintenance is permitted.

What is the most significant aspect of an intrinsically safe system?

While flameproof equipment requires correct electrical protection and isolation, the most significant aspect of an intrinsically safe system is ensuring that the apparatus within it is compatible.

Why is live maintenance possible with intrinsic safety?

The intrinsic safety technique permits live maintenance within the hazardous area without the need to obtain ‘gas clearance’ certificates. This is particularly important for instrumentation, since fault-finding on de-energised equipment is difficult.

Can simple apparatus be added to an intrinsically safe system?

The apparatus standard allows simple apparatus to be added to an intrinsically safe system without the need to recalculate the safety of the system. It imposes limits of 1.5V, 100mA, and 25mW on the values generated by simple apparatus.
