The criterion has been removed. The requirements are therefore no longer applicable.
At grid feed-in points, voltage quality is monitored in accordance with EN 50160 (or IEC/TS 62749).
At feed-in points from additional supplies (NEA, etc.), voltage quality is monitored in accordance with EN / IEC 61000-2-4.
Energy consumption values (active power and active energy) are recorded in the primary and secondary distribution systems using meters and current transformers of accuracy class 1 or 1 S (measurement accuracy ±1.0%).
The arrangement of the measuring instruments is carried out with granularity level 2 in accordance with EN 50600-2-2 or ISO/IEC 22237-3.
C: Implementation is as described above in the text.
Change to the catalogue: The meters for recording power and energy now have an accuracy of +/- 1% throughout, instead of +/- 0.5% in primary distribution systems.
