the PT/CT ratio again.
Notes:
(1) IEC61850-9-2(d1.0 and Ed2.0): In the SMV testing components, the CT/PT ratios of G1,
G2, G3 and G4 are “Ua, Ub, Uc, Ia, Ib, Ic”, “Ua`, Ub`, Uc`, Ia`, Ib`, Ic`”, “Usa, Usb, Usc,
Isa, Isb, Isc” and “Uta, Utb, Utc, Ita, Itb, Itc”. The CT/PT ratios of G1, G2, G3 and G4 are
respectively relevant with the four sampling output control parts.
(2) The parameter interfaces are only corresponding to the parameter setting method such
as primary or secondary. The actual outut primary value or secondary value is decided
by the GOOSE output method. When the methods of parameter setting and GOOSE
output are different, the CT/PT ratio should be set.
(3) The positive and negative logic of IRIG-B are corresponding to the site IRIG-B source
that applies the rise triggering or drop triggering. When it is selected fault, it will affect the
synchronization of tester and time and can’t track the time source.
(4) When the “Single” is selected in fiber optic connection, the fiber optic port can only
receive or only send. It doesn’t affect “Dual” function. But it can’t work visa versa.
(5) If the fiber optic is single, the indicator will light. When it is dual, the indicator will light
with correct wiring connection.
(6) IEC61588 synchronization mode: Select related 1588 communications type for site
applications.
(7) Users are required to select the correct message output format. Otherwise, it will affect
the test results.
(8) Low level signal output: Set if the low level signal outputs simultaneously with
IEC61850-9-2/IEC60044-8.
(9) Test object’s IP address: when the software communicates with the test object.
(10) The italic protocols are only used in defined coutries or areas.
