IEEE Codes and Standards

IEEE C62.41.1, “Guide on the Surge Environment in Low-Voltage (1000 V and less) AC Power Circuits”
This guide, the first in the trilogy, provides readers with comprehensive information on surges, the environment in which they occur and is a reference for the second document of the trilogy.

IEEE C62.41.2, “Recommended Practice on characterization of Surges in Low-Voltage (1000 V and less) AC Power Circuits”
This guide, the second in the trilogy, presents recommendations on the selection of surge waveforms, amplitudes of surge voltages and currents used to evaluate equipment immunity and performance of SPDs. Two recommended “standard” waveforms are used as a simplified representation of the surge environment:

IEEE C62.45, “Recommended Practice on Surge Testing for Equipment Connected to Low-Voltage (1000 V and Less) AC Power Circuits.”
This guide, the third in the trilogy, focuses on surge testing procedures (using simplified waveform representations) for obtaining reliable measurements and enhancing operator safety. The intent is to provide background that can help determine whether equipment or a circuit has adequate ‘withstand’ capability. Signal and data lines are not addressed in this document.

The document does not indicate withstand levels that might be assigned to specific equipment. An important objective of the document is to call attention to the safety aspects of surge testing. Underwriters Laboratories, Inc. uses these guidelines as a reference in their performance and safety testing.

In addition, IEEE has produced the following standards for the application and testing of SPDs.
