There’s a new IEEE 4, “IEEE Standard for High-Voltage Testing Techniques,” that’s just been released. The standard is one of the oldest titles in the IEEE collection, with the first edition dating back to 1928. This new 2013 update is the 8th Edition.
IEEE 4-2013 establishes standard methods and basic techniques for high-voltage testing. The standard is applicable to all types of apparatus for alternating voltages, direct voltages, lightning impulse voltages, switching impulse voltages, and impulse currents. It is applicable only to tests on equipment with a rated voltage above 1000 V.
IEEE 4 is intended to define terms of general applicability, provide general requirements for test equipment and procedures, and to describe various methods for the evaluation of the test results. You’ll find procedures for applying correction factors to convert test data to standard atmospheric conditions. And methods are supplied for testing equipment when external insulation of the test object is to be subjected to dry, wet, or contaminated conditions.
There is no guidance in the document itself for determining exactly where changes have been made. However, the revision has reorganized the technical content so that the sections that deal with alternating voltage, direct voltage, and impulse voltage testing are grouped together. Also, it introduces the concept of measurement uncertainty in evaluation of high-voltage and high-current tests.
The previous 7th Edition was issued in 1995 but of course it was made obsolete with the release of the 2013 revision.
