Imbalance in three-phase electrical circuits can be caused by several different sources: a power delivery problem, low voltage on one leg or an insulation resistance breakdown inside the motor windings. This imbalance can lead to motor deterioration, excessive energy costs, blown fuses and system failures.
This application note describes ways to detect electrical imbalances and overloads with thermal imagers, and how to resolve them before they become emergencies. You'll learn:
- What to check
- What to look for
- What represents a "red alert"
- How to determine the potential cost of failure
- How to deal with unbalance and overload issues
See how Fluke thermal imagers can help you improve three-phase electrical circuit inspections, while reducing the time and cost of systems maintenance.
