DIRIS A17
9. Connection test function
During the test, the DIRIS must have current and voltage for each of the phases.
In addition to this, the function recognises the PF of the installation as being between 0.6 < PF < 1. If the PF of the
installation is not within this range, this function cannot be used.
- In 4 BL / 3 BL, only the connection of the CTs is controlled.
- In 4NBL and 3NBL the connection as a whole is controlled.
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
- Errors 1, 2 and 3 must be corrected manually by reversing CT connections.
- Errors 4, 5 and 6 must be corrected manually by modifying voltage connections.
