Example 2
In the following diagram 3 dASM groups are connected to the three-phase network with three
single-phase Thyro-P devices each.
Even in a case where patch cables were connected between units 3 and 4, or 6 and 7, this configu-
ration would generate the 3 dASM groups illustrated. This is caused by the varying activation of the
Thyro-P devices in the power grid (unit 3 ≠ unit 4 unit 6 ≠ unit 7).
The first Thyro-P in the dASM group in each case takes on the ʺmasterʺ function for grid load op-
timization of the dASM group. For an activation unit setup with 3 dASM groups up to 3 X 32 = 96
Thyro-P devices could be connected.
Because as many dASM groups with 32 Thyro-P devices each can be realized for grid load optimi-
zation, assemblies which are as large as desired (with as many Thyro-P devices in total as desired)
can be equipped with grid load optimization.
Example 3 shows the following configuration:
dASM group from unit 1 (M): 3 x Thyro-P
dASM group from unit 4 (M): 3 x Thyro-P
dASM group from unit 7 (M): 3 x Thyro-P
Example 2a:
In contrast to example 2 the power wiring of Thyro-P unit 4 is not connected in phase with units 5,
6. This is why, in the diagram which follows, the following configurations have arisen:
dASM group 1: unit 1 (M): 3 x Thyro-P
dASM group 2: unit 4 (M): 1 x Thyro-P
dASM group 3: unit 5 (M): 2 x Thyro-P
dASM group 4: unit 7 (M): 3 x Thyro-P
As a result of the connection not being in phase in this switching arrangement, in contrast with the
switching arrangement from example 2, a suboptimal grid load optimization occurs.
