The house has a three-phase input. In the VPU, a sealed three-pole automatic Schneider 25A then a three-phase meter. After the three-pole IEK 25A, then with a VVGng 4 * 10 cable into the shield in the house on the three-pole C25 legrand. I send three phases and zero from the legrand to the cross-module. From the cross-module I connect phase A and zero to the first 10 kW Resant stabilizer. Phase B with zero to the second stabilizer. C and zero for the third. From the outputs of the stabilizers I connect A and N, B and N, C and N to another cross-module. From it I send three phases and zero to the shield for the load. When three stabilizers are turned on, it knocks out the input in the shield and two machines in the VPU even without a load. When you turn on any one stabilizer, it works with the load too. Moreover, at the input of the stabilizers with the machine turned on, the network, the resistance between the phase and zero is 0.5 Ohm. They work through the bypass. If anyone can tell I will be grateful. I tried to describe in more detail. The stabilizers are new, not relay ones, but with this thing that rotates and removes the voltage from the secondary winding through the brushes
