The EN 50160 Voltage characteristics of electricity supplied by public networks is a European standard which the essential features of the mains voltage defined at the network connection point under normal operating conditions and specified.
In Germany the standard is valid as DIN standard DIN EN 50160.
The characteristics of the supply voltage are defined in terms of frequency, level, curve shape and symmetry of the external conductor voltages. During normal network operation, load fluctuations , disturbances and the occurrence of errors such as B. short circuits to permanent changes in the features described above.
Essential parameters are the frequency , the voltage level , the curve shape and the symmetry of the conductor voltages . For this purpose, EN 50160: 2010 specifies an interval of 49.5 Hz to 50.5 Hz for 99.5% of the time for networks with a synchronous connection to an interconnected network. H. In around 44 hours per year, the frequency can be expanded to an interval of 47 Hz to 52 Hz.
The voltage changes should not exceed ± 10% of the nominal voltage U n ; in cases without a connection to a transmission network or when supplying remote customers, +10% / - 15% U n are permissible. Under normal operating conditions, 95% of the 10-minute mean values of the measured effective value of each weekly interval must be within the limits of ± 10% U n .
