An interactive tutorial

Arc Flash &
Short-Circuit

Build a small system, read the bolted fault current at the bus, plug it into the IEEE 1584 model, and watch the PPE category move as the protective device's clearing time changes. The natural sibling to the TCC coordination tutorial.

Course Outline

Module 1

Short-Circuit Fundamentals

Where the fault current actually comes from.

  1. L1 What is a Short-Circuit?
  2. L2 Calculating Isc at a Bus

Module 2

Arc Flash

Plasma physics, IEEE 1584, labels and PPE.

  1. L3 What is an Arc Flash?
  2. L4 The IEEE 1584 Model
  3. L5 Labels, PPE, and Boundaries

Module 3

Mitigation

Reduce fault current, reduce clearing time.
