How We Do It

Data Collection

The process begins with comprehensive data collection, where detailed information is gathered on all aspects of the power system, including equipment ratings, single-line diagrams, relay settings, and system configurations. Accurate and up-to-date data is crucial for performing reliable analyses.

Short Circuit Study

A short circuit study is performed to determine the available fault current at various points within the system. This analysis identifies the system’s ability to withstand and interrupt fault conditions, ensuring that protective devices can safely handle short circuits.

Arc Current Calculation

Using the results from the short circuit study, the arc current is calculated. This step involves determining the potential arc flash currents under fault conditions, which serves as the basis for subsequent safety and protection calculations.

Protection Coordination Study

A protection coordination study is then conducted to analyze and optimize the settings of protective devices. The goal is to ensure that devices operate in a coordinated manner to isolate faults while minimizing system disruptions.

Incident Energy Calculation

The next step involves calculating the incident energy, which determines the energy released during an arc flash event. This calculation is critical for assessing the potential hazards to personnel working on or near the electrical equipment.

Flash Boundary Calculation

Based on the incident energy results, the flash boundary is calculated. This boundary defines the safe distance from the electrical equipment, where the risk of injury due to an arc flash is minimized.

Report and Labeling

A detailed report is generated that includes all study results, calculations, and recommendations. Arc flash labels are also created for electrical equipment to ensure proper identification of arc flash hazards and to inform personnel of the required personal protective equipment (PPE) levels.

Mitigation Activities

Finally, mitigation activities are recommended and implemented to reduce the risk of arc flash incidents. This can include equipment upgrades, system reconfiguration, or changes to protection settings to enhance the safety and reliability of the power system.

Steps to Ensure Electrical Safety

(From Most Effective to Least Effective)

Elimination:

Avoid working on energized equipment altogether unless absolutely necessary. In this way there is no risk of electrocution to personnel.

Substitution:

Design equipment with features that allow tasks to be performed while maintaining a closed and guarded condition or that reduce the risk to personnel in the event of a failure.

Engineering Controls:

Apply safeguards and isolate the hazards from the personnel with barriers and mechanical.

Administrative Controls:

Policies, procedures, work practices and training to help reduce the risk to personnel and ensure only qualified personnel undertake tasks.

PPE:

Utilized Personal Protective Equipment to help minimize risks to personnel.
