UMG 104

Current measurement connection
options

The UMG104 recognises two connection
options for the current measurement.

Connection option 0

•

Measurement via 3 current transformers
in three-phase 4-conductor systems.

•

Measurement via 2 current transformers
in systems with the same load.

•

Measurement in one-phase-3-conductor
systems.

Connection option 1

•

Measurement via 2 current transformers
(Aron circuit) in three-phase 3-conductor
systems.

Address Connection option

110

0 = Three current transformers.

(Default factory setting)

1 = Two current transformers

(Aron circuit)

Fig. 49.1 Section of the parameter list for the
current transformer connection options.

For the inputs L4 and I4 are no con-
nection schemes required.
