Arc Flash Hazard Assessment & ETAP Power System Study Malaysia

What Is Arc Flash?

Arc flash is a dangerous electrical fault that releases high levels of thermal energy. It can cause serious injury, equipment damage, fire and production downtime. The risk is present in many electrical installations, especially where high fault levels, incorrect protection settings or exposed electrical work are involved.

What Saturn Pyro Provides

Scope of Arc Flash Hazard Assessment

• Site assessment and review of existing electrical installation
• Review and update of electrical Single Line Diagram
• Collection of transformer, cable, switchgear, breaker and relay data
• Data entry and validation in ETAP power system modelling software
• Short circuit analysis and protection coordination study
• Load flow study to understand system loading and operating conditions
• Arc flash incident energy calculation and hazard boundary determination
• Preparation of arc flash warning labels and final engineering report
• Awareness briefing and training support for site personnel

Why ETAP Power System Study Is Important

ETAP allows the electrical system to be modelled as a digital representation of the facility. This enables simulation of normal operating conditions and fault conditions without interrupting production.

• Creates a structured digital model of the electrical network
• Helps validate short circuit levels and protection device behaviour
• Highlights protection coordination concerns and improvement actions
• Supports arc flash calculation based on actual system data
• Provides a stronger engineering basis for electrical safety decisions

Typical Deliverables

Client Information Required

• Latest available electrical Single Line Diagram
• Access to electrical rooms, panels, switchboards and equipment nameplates
• Transformer, breaker, relay, cable and load information where available
• Existing relay settings, breaker settings and protection data
• Historical electrical issues, trip incidents or safety concerns
• Site escort and safe access for visual data collection

In most cases, the data collection is visual and non-intrusive. A shutdown is normally not required unless specific testing or inaccessible equipment verification is requested separately.

Arc Flash Warning Labels

Arc flash labels provide important safety information at the equipment location. A typical label may include equipment name, voltage, incident energy, arc flash boundary, working distance, PPE requirement and shock approach boundary information.

Standards and References

Arc flash assessment is commonly aligned with recognised electrical safety and calculation references such as NFPA 70E, IEEE 1584 and workplace electrical safety requirements. These references support arc flash assessment, incident energy calculation, warning labels, PPE selection and safe work practices.
