DIRIS A20

COnneCTiOn TeST fUnCTiOn

During the test, the DIRIS must have current and vol-
tage for each of the phases.
in addition to this, this function needs to have a load
of at least 20% over the rated load with a power fac-
tor (PF) between 0.6 inductive <PF <1.
if these two criteria are not met, this function can not
be used, and the test will not start.
in 4BL / 3BL / 2BL / 1BL, only the CTs connection is
controlled.
in 4nBL and 3nBL, the entire connection is control-
led.
Do check that these are the right conditions:
Err 0 = no error
Err 1 = CT phase 1 inverted
Err 2 = CT phase 2 inverted
Err 3 = CT phase 3 inverted
Err 4 = V1 and V2 voltages inverted
Err 5 = V2 and V3 voltages inverted
Err 6 = V3 and V1 voltages inverted.
For the err 1, err 2 and err 3, the modification can be
performed automatically by the DiRiS or manually by
correcting the current connections.
For the err 4, err 5 and err 6 the modification must
be performed manually by correcting the voltage
connections.
