You need to reduce operational costs by remaining in low voltage range distribution. You also want to provide a high level of security by reducing the stress on the electrical installation. To achieve these goals, you need a compact solution, without MV/LV transformers and reducing safety distances.
As installed power on board increases permanently, electrical distribution can require a shift from low volatge to medium voltage design. The Masterpact UR ultra rapid bus tie allows much higher installed power with a low voltage design by strongly limiting the very high short circuit current and related energy faults.
