Evaluation Services for Intrinsically Safe and Non-incendive Electrical Systems
Intrinsically safe is a system concept and it is necessary to consider the safety of each component of the system in the loop. Installation of an intrinsically safe system to connect a safety barrier to a field device requires a precise assessment. The Code of Practice for such installations must be strictly adhered to in order to ensure that the installation is safe. Combinations of devices to a safety barrier may get more complex if there are two or more barriers feeding an IS device.
Our engineering services for your intrinsically safe installations in hazardous areas include:
- Providing fault assessments, spark assessments, thermal assessments and supporting calculations for field wiring installations
- Preparation of engineering documents:
- SEALED & STAMPED descriptive system documents required for the installation and verification of an intrinsically safe system
- control drawings and intrinsically safe block diagrams with details of electrical parameters governing interconnections of the associated apparatus and intrinsically safe devices
- Evaluation Services:
- entity parameters of intrinsic safety barriers and intrinsically safe field devices for a safe installation
- electrical parameters for interconnecting wiring
- grounding and bonding requirements of safety barriers and IS devices in hazardous areas
- Verification of:
- temperature class (T-code), gas or dust groups, the equipment protection level (EPL)
- conditions for safe use of certified devices
We provide engineering evaluations on intrinsically safe and non-incendive installations in hazardous areas (Division and Zone systems).
