6.7.7 EN50160 Confi guration
The EN50160 standard defi nes limiting values and permissible variations of the
voltage quality for the European Community. It defi nes which parameters are rel-
evant, and how are they measured. Continuous or random sampling control of the
voltage quality provides the supplier of electric energy with a reliable basis when
dealing with network problems, and it contributes to quality assurance.
The purpose of the EN50160 standard "Voltage characteristics of electricity sup-
plied by public distribution systems" is to specify the characteristics of the supply
voltage with regard to the course of the curve, the voltage level, the frequency and
symmetry of the three phase-network at the interconnecting point to the customer.
The goal is to determine limiting values for regular operating conditions.
However, facility defects may lead to major disturbances in the electricity distribu-
tion supply network. Accordingly, the standard establishes these values as limiting
values, which are not allowed to be exceeded on the high or low side during 95%
of the controlled period typically one week.
