11. IEC 61000-4-27p Voltage Unbalance Immunity Testing
11.1 About This Chapter
This chapters covers testing a device for compliance with the IEC 61000-4-27 Voltage Unbalance
in three phase AC power systems. test standard. This test is supported through the CIGUI32 or
CIGuiSII AC source control program. If you purchased a 100-CTS or 300-CTS test system, which
does not include a California Instruments AC source, you will not be able to perform these tests.
This test is only available on three-phase CTS Systems as it involves voltage and phase
unbalance between three phases of a three phase supply network. The IEC 61000-4-27
implementation in the CIGUI32 or CIGuiSII is based on the IEC 61000-4-27 standard dated 2000-
08. Test levels and durations can be changed if needed through use of one or more filename.427
files in the IEC_Test directory.
