Arc Flash Hazard Assessment & ETAP Power System Study Malaysia
Saturn Pyro provides Arc Flash Hazard Assessment and ETAP Power System Study services for industrial, commercial and utility electrical installations throughout Malaysia.
The study helps identify arc flash risk, calculate incident energy, review protection settings, update electrical single line diagrams, define boundaries, prepare warning labels and support safer electrical work practices.

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.
Arc flash risk cannot be fully removed, but it can be assessed, labelled and reduced through proper power system study, protection coordination, safe work procedures, PPE selection and training.
The Key Message: Do Not Guess the Risk
Arc flash hazard level depends on available fault current, protection clearing time, working distance and equipment configuration. These must be calculated from actual electrical system data.
- Fault current
- Breaker clearing time
- Relay settings
- Working distance
- Equipment condition
- System configuration

Scope of Arc Flash Hazard Assessment
- Site assessment
- Review existing electrical installation
- Update electrical Single Line Diagram
- Collect transformer and cable data
- Collect switchgear, breaker and relay data
- ETAP data entry and validation
- Short-circuit analysis

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.
Digital Electrical Model Creates a structured engineering model of the actual electrical network.
Fault and Protection Behaviour Validates short-circuit levels, protection device behaviour and clearing time.
Safety Decision Support Provides a stronger basis for PPE, labels, boundaries and electrical safety decisions.

Client Information Required
- Latest electrical SLD
- Electrical room access
- Panel and switchboard access
- Transformer information
- Breaker and relay data
- Cable information
- Existing protection settings

- Site escort and safe access
In most cases, 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.
