The ITIC curve (formerly CBEMA) is a performance-oriented standard for electronic equipment manufacturers. The standard gives a method for classifying and plotting voltage events on a specially constructed graph that defines regions of continued operation, equipment failure, and damage. A simplified presentation is described here for identifying likely ITIC events on a standard RMS voltage stripchart graph. This method is easier for correlating voltage events with load changes and can be more understandable to residential utility customers.

This white paper includes:

• CBEMA basics
• Stripchart data
• ITIC events in the stripchart
