Understanding and Managing Voltage Transients in Electrical Systems
This white paper explores the nature, causes, and classifications of voltage transients as defined by IEEE Std 1159-2019. It distinguishes between impulsive and oscillatory transients, outlines their subcategories based on rise time and frequency, and discusses their impact on electrical equipment. The paper also highlights typical sources, such as lightning and switching events, and reviews mitigation strategies including surge suppressors and line reactors.Key topics include:
- Definition and Classification of Transients
- Impulsive Transients
- Oscillatory Transients
- High, Medium, and Low Frequency Oscillatory Transients
- Measurement and Characterization
Why utilities should care:
Accurate identification and mitigation of voltage transients reduces equipment failures, prevents costly outages, and ensures compliance with power quality standards. Understanding transient behavior enables better protection strategies and enhances system reliability and operational efficiency.
