6.6.7 EN50160 Configuration
TheEN50160standarddeneslimitingvaluesandpermissiblevariationsofthe
voltage quality for the European Community. It denes which parameters are
relevant, 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 distribution
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.
