Comparative Analysis of Arc Flash Solutions -A Case Study

摘要

This paper evaluates several active and passive arc flash reduction solutions based on IMFPA 70E. A case study simulation is performed on an existing conventionally coordinated low-voltage switchgear system based on IEEE 1584-2018 standard, and the comparative results are presented. For each solution, the concept, the achievable energy levels and the associated cost of implementation are provided. A discussion of trade-offs and benefits of various solution is presented to help electrical safety supervisors make a sound judgment according to their requirements.
