Short Circuit Analysis

A short circuit (a.k.a. fault) occurs when two or more live parts form an unintended contact, resulting in an immediate surge of electrical current.

This could create dangerous conditions that threaten human safety and compromise equipment integrity.

To identify these hazardous conditions and prevent equipment damage, a customer can proactively request a Short Circuit Analysis.

Arc Flash Hazard Analysis

An arc flash hazard is the danger of injury or damage caused by an explosive release of electrical energy due to a fault, equipment failure, or accidental contact with live wires.

The fault creates an arc, which is a bright flash of light, intense heat, and a powerful pressure wave capable of causing severe burns, flying shrapnel, serious injuries and even fatalities.

Proper safety practices can substantially lower the risk of such incidents.

Protective Device Coordination

Protective device coordination is the process of strategically selecting fuses and adjust settings of circuit breakers to isolate faults in an electrical system.

This process ensures the protective device closest to the fault opens first, preventing unnecessary outages to other parts of the system.

A protective device coordination study analyzes the electrical system to optimize device settings for both protection and service continuity.

Equipment Evaluation Report

The equipment evaluation builds upon the short circuit analysis and provides a summary of whether the equipment is properly rated for the calculated fault conditions.

The worst case calculated fault currents presented in the short circuit analysis were compared against the interrupting and withstand ratings of the existing equipment surveyed.

The report presents both the calculated short circuit values and the corresponding equipment manufacturer ratings.
