V connection; Aron connection
The V connection or Aron connection can be configured in the device set-up of
the software. These connection types are only available in the 3-wire configura-
tion.
1) V connection (parameterisation via the evaluation software)
2) Aron connection (parameterisation via the evaluation software)
Posssible connection configurations in 3-wire grids:
Voltage converter connections: 1, 2, 3, 4,
Current transformer connections: 1, 2, 3, 4,
The voltage converter and current transformer selection fields can be parame-
terised. The grounded voltage in each case or the current that has not been
connected is calculated by the measuring device.
