Understanding Intrinsically Safe Systems

Intrinsically safe systems are designed to prevent the ignition of explosive atmospheres by limiting the energy available for ignition. This is achieved through the use of specialized equipment and techniques that control electrical and thermal energy. The PD CLC IEC/TS 60079-39:2019 standard specifically addresses systems with electronically controlled spark duration limitation, providing a framework for designing and implementing these systems effectively.

Why Electronically Controlled Spark Duration Limitation?

In environments where explosive gases, vapors, or dusts are present, even a small spark can lead to catastrophic consequences. Electronically controlled spark duration limitation is a cutting-edge approach that minimizes the risk of ignition by precisely controlling the duration and energy of electrical sparks. This technology is particularly valuable in industries such as oil and gas, chemical processing, and mining, where safety is of utmost importance.

PD CLC IEC/TS 60079-39:2019

This standard PD CLC IEC/TS 60079-39:2019 Explosive atmospheres is classified in these ICS categories:

• 29.260.20 Electrical apparatus for explosive atmospheres

This Technical Specification specifies the construction, testing, installation and maintenance of Power-i apparatus and systems which utilise electronically controlled spark duration limitation to maintain an adequate level of intrinsic safety.

This Technical Specification contains requirements for intrinsically safe apparatus and wiring intended for use in explosive atmospheres and for associated apparatus intended for connection to intrinsically safe circuits entering such atmospheres.

This Technical Specification excludes the level of protection “ia” and the use of softwarecontrolled circuits.

This Technical Specification applies to electrical equipment utilising voltages not higher than 40 V d.c. and a safety factor 1,5 for Groups IIB, IIA, I and III. It is also applicable to Group IIC “ic” apparatus with a safety factor 1,0. Group IIC “ib” apparatus with a safety factor 1,5 are restricted to voltages up to 32 V d.c.

This type of protection is applicable to electrical equipment in which the electrical circuits themselves are incapable of causing an explosion of the surrounding explosive atmospheres.

This Technical Specification is applicable to intrinsically safe apparatus and systems which utilise electronically controlled spark duration limitation with the aim of providing more electrical power while maintaining an adequate level of safety.

This Technical Specification is also applicable to electrical equipment or parts of electrical equipment located outside hazardous areas or protected by another type of protection listed in the IEC 60079 series, where the intrinsic safety of the electrical circuits in explosive atmospheres depends on the design and construction of such electrical equipment or parts of such electrical equipment. The electrical circuits located in the hazardous area are evaluated for use in such locations by applying this Technical Specification.

This Technical Specification supplements and modifies the requirements of IEC 60079-0, IEC 60079-11, IEC 60079-14, IEC 60079-17 and IEC 60079-25.
