Is it possible to connect two 0.4 kV lines from different transformers to each other?
Please tell me, is it possible to connect two 0.4 kV lines, powered from different transformers, to each other and what is needed for this?

Hello! The practice of including transformers for parallel operation. But at the same time, the conclusions of the same name are connected not only of the secondary windings (0.4 kV), but also of the primary windings (6 or 10 kV). To enable transformers for parallel operation, the following conditions must be fulfilled: equality of short-circuit voltages (+/- 10% is allowed), difference in rated power of transformers is not more than 1 to 3, equality of winding connection groups, equality of transformation coefficients (+/- 0, 5%).
