IEEE 400.2-2013

IEEE 400.2-2013 is a technical guide for field testing shielded power cable systems using very low frequency (VLF) signals below 1 Hz. It addresses how these cable systems may be evaluated in service or before commissioning, helping engineers and utilities apply consistent test practices. As an inactive IEEE standard, IEEE 400.2-2013 remains relevant as a reference for insulation assessment, diagnostic planning, and controlled testing of underground and other shielded cable installations.

What is IEEE 400.2-2013?

This standard provides guidance for field testing shielded power cable systems with very low frequency methods, typically used when conventional high-voltage AC testing is not practical. The document focuses on the technical context of cable insulation evaluation, test setup, and interpretation considerations for shielded cable installations. It is part of the IEEE 400 family of cable testing guides and is most useful when a consistent, documented approach is needed for performance verification and maintenance testing.

Where is IEEE 400.2-2013 used?

IEEE 400.2-2013 is commonly used in power and energy environments where shielded cables must be tested on site, such as utility distribution networks, industrial plants, and large facilities with underground cabling. It is relevant to test crews, maintenance teams, and engineers working with VLF test equipment, cable accessories, and insulation diagnostics. The guide may also support acceptance or maintenance workflows where safe, repeatable field testing of shielded power cable systems is required.

Why is IEEE 400.2-2013 important?

This guide helps improve consistency in field testing by giving users a common technical reference for VLF evaluation of shielded power cable systems. That can support better compliance decisions, reduce ambiguity in procurement or specification work, and help limit risk from incorrect test practices. For organizations responsible for cable reliability, IEEE 400.2-2013 offers a practical basis for comparing results, documenting procedures, and making more informed maintenance or replacement decisions.
