Optimization and Design of a Sustainable Industrial Grid System

Table 2

Percentage of allowable voltage drop by IEC 60364 : 2001.

Voltage drop points	Lighting (%)	Other uses (%)
1. Public low voltage distribution system supplying LV distribution systems	3	5
2. Private low voltage distribution system supplying LV distribution systems	6	8

^∗When the main wiring systems of the installation are longer than 100 m, these voltage drops may be increased by 0.005% per meter of wiring system beyond 100 m, without this supplement being greater than 0.5%.
