When reducing voltage on the distribution side, a typical reduction of 2.5% to 5% is considered appropriate for maintaining system reliability and ensuring efficient operation. This range helps in managing voltage levels without causing significant disruption to the equipment connected to the distribution system. A reduction of this magnitude strikes a balance between reducing losses and maintaining the functional integrity of electrical devices that rely on stable voltage levels.

Larger reductions, like those above 5%, could lead to performance issues for sensitive equipment or insufficient voltage being delivered to end-users. Keeping the voltage reduction within the 2.5% to 5% range helps to avoid such complications while still achieving some degree of efficiency improvement in the system.
