Multiple fault on a double-circuit line next to a generato
Figure 6-14
Address $ 7ULSSK)OW determines that the short-circuit protection functions
perform only a single-pole trip in case of isolated two-phase faults (clear of ground),
provided that single-pole tripping is possible and permitted. This allows a single-pole
rapid automatic reclosure cycle for this kind of fault. The trip type can be set to SROH
OHDGLQJ SKDVH or SROH ODJJLQJ SKDVH. The parameter is only available in
versions with single-pole tripping. This setting can only be changed with DIGSI
under "Additional Settings". If this option is used, it must be born in mind that the
phase preference should be the same throughout the entire network and that it must
be the same at all ends of one line. More information on the function is also contained
in Section 6.20.3 Overall Fault Detection Logic of the Device. The default setting is
WULSOHSROH.
Note: The indicated secondary current values and values of impedance for setting
ranges and default settings refer to I
values are to be multiplied by 5. The values of impedance are divided by 5.
