7. Calculating voltage drops

Reference voltage

The regulatory value of the voltage at the point of delivery was set by the Order of May 29, 1986 on "normal voltages of 1 ^re category electrical power distribution networks". This decree sets the nominal voltage of low-voltage AC electrical power distribution networks at 230 V for single-phase current and 400 V for three-phase current.

It also specifies the minimum and maximum voltages at delivery points, for single-phase current: 207 V and 244 V, and for three-phase current: 358 V and 423 V. These values must be strictly adhered to for consumer connections and for delivery points with extraction from "producer-consumer" connections.

For specialized injection delivery points on "producer-consumer" connections, in agreement between...
