Electricity powers industries, businesses, healthcare facilities, schools, and homes. While it enables growth and productivity, electrical systems must be carefully managed to prevent hazards.
One potential hazard is an Arc Flash a sudden electrical explosion that can cause injury, equipment damage, and operational disruptions.
At Cusum Energy, we help organizations identify, assess, and reduce these risks through comprehensive Arc Flash Studies.
What is an Arc Flash?
An Arc Flash occurs when electrical current leaves its intended path and travels through the air between conductors or to the ground. This sudden release of energy can result in:
-
High temperatures
-
Pressure waves
-
Bright light and heat
-
Molten material projected at high speed
-
Loud sound levels
Even a single incident can be serious for workers and may affect operations.
What is an Arc Flash Study?
An Arc Flash Study is an engineering assessment that evaluates potential hazards in an electrical power system. The study helps organizations understand:
-
Where arc flash hazards may occur
-
The severity of those hazards
-
How to protect workers, equipment, and facilities
Key Steps in an Arc Flash Study
-
System Data Collection
Engineers gather information about transformers, panels, switchgear, protective devices, and load data. -
Short-Circuit Analysis
Fault levels are calculated to identify areas with high energy release potential. -
Protective Device Review
Breakers, relays, and fuses are analysed to ensure they respond effectively. -
Arc Flash Hazard Assessment
Data is used to determine the potential severity of events at different points in the system. -
Labelling and Documentation
Equipment is labelled to help workers understand the risks and take appropriate precautions. -
Mitigation Recommendations
Practical steps, such as equipment upgrades, maintenance improvements, and safer operational practices, are proposed to reduce exposure.
Why is an Arc Flash Study Important?
Conducting a study is a proactive safety and business decision. Benefits include:
-
Protecting Lives – Reduces risk of incidents for employees and contractors
-
Reducing Equipment Damage – Minimizes costly repairs or replacements
-
Avoiding Downtime – Supports smooth operations by preventing outages
-
Promoting a Safety Culture – Encourages awareness and accountability
-
Future-Proofing Operations – Supports reliable and resilient electrical systems
Who Should Conduct an Arc Flash Study?
Facilities with complex or high-power electrical systems may benefit, including:
-
Manufacturing industries
-
Commercial buildings
-
Hospitals and healthcare facilities
-
Educational institutions
-
Energy utilities and renewable energy plants
-
Data centers and ICT hubs
