Advanced Intrinsic Safety Circuit Design

Advanced Intrinsic Safety Circuit Design

This 3 day workshop based training is the most advanced Intrinsic Safety designers course available.

This course is for Engineers who wish to master designing intrinsically safe equipment and learn some new methods of achieving safety used in the latest editions of the intrinsically safe standard for high power and non-linear devices.

This workshop has been specifically developed to incorporate the very latest thinking on intrinsic safety and the most advanced certification techniques available for high power and non-linear circuits.

The classes are based on a number of ‘hands on’ exercises with full worked solutions and assumes a prior Knowledge of basic intrinsic safety. The core syllabus covered includes:

• Determination and assessment of linear & non-linear output parameters (including transients).
• Domain analysis to increase efficiency whilst also meeting intrinsic safety requirements.
• Rating of components such as resistors, fuses, diodes in a Zener barrier (and infallibility).
• Implementation techniques for Antennas, DC-DC converters, and semiconductors current limiters.
• Identifying areas where infallible connections can be used and improve efficiency.
• Methods for temperature classification of encapsulated areas, troubleshooting non-conformance, and implementing heatsinks.
• Temperature classification of batteries.
• Surface temperature of intrinsically safe circuits for combustible dust.
• Understanding separation distances requirements and enclosures requirements.

If you are not currently designing basic intrinsically safe circuits we would recommend starting with the introduction to intrinsic safety course.

Three Day Advanced Intrinsic Safety Training Course and Workshop Syllabus

Exercises based real cases examples covering all relevant aspects of the standard. The workshop will include 20 exercises with full explanations and where appropriate advanced tools/spreadsheets and samples/datasheets will be provided.

The Certification Design Workshop covers ATEX, IECEx, NEC500 & 505 Circuit Designs for ‘Global’ Design Compliance.

Typical workshop exercises include:

  • Linear circuits output parameters determination and assessment.
  • Linear circuits input parameters determination and assessment.

  • Non-linear output parameters determination and assessment.
  • Linear circuits output parameters determination and assessment including transients
  • Dividing a circuit in domains to meet the requirements and keep efficiency.
  • Determination of maximum constant parameters for circuits based on resistor, fuse and Zener diodes. Including the idea of matching resistance and fault conditions of components.
  • Dealing with components non-conform with the temperature class requirements.
  • Determination of methodologies for temperature classification of encapsulated areas.
  • Temperature classification of batteries.
  • Surface temperature for combustible dust IS circuits.
  • Show the relation of separation distances requirements and enclosures requirements.
  • Determining requirements for separation distances according to Table 5 or Annex F.
  • Determination of areas where infallible connections shall be used.
  • Determination of areas where infallible connections would help on improving efficiency.
  • Rating infallible components parameters for a linear Zener barrier.
  • Dealing with Zener diodes ratings non-conformance and implementing heatsink.
  • Dealing with Antennas on IS circuits
  • Dealing with boost converters
  • Dealing with step-down DC-DC converters
  • Dealing with semiconductors current limiters and testing per Annex G
