IEEE STANDARD

ANSI/IEEE 339-1972 - IEEE Standard Requirements for Switching-Impulse Voltage Insulation Strength for AC High Voltage Circuit Breakers Rated on a Symmetrical Current Basis (362 kB and Above)

Description: The purpose of this standard is to define the special terms used, to provide a rating structure, and to provide a dielectric test procedure. It specifies methods of testing, conditions during tests, and wave shapes to be used for switching-impulse voltage testing. This standard is intended as an addition to the American National Standards for ac high voltage circuit breakers rated on a symmetrical current basis: C37.03-1964 (R1969); C37.04-1964 (R1969); C37.05-1964 (R1969); C37.06-1971; C37.07-1969; C37.09-1964 (R1969); C37.010-1964 (R1969); C37.12-1969; and their supplements. It is planned to eventually incorporate its contents in these basic circuit breaker standards.
