For defining a measurement uniquely, a short description (z.B. U
1N
) and a unit (z.B. V) are not sufficient.
Therefore additional symbols are used for defining the measurement type:
Mean-value
Inductive load
Mean-value trend
Capacitive load
Bimetal function (current)
Maximum value
Energy demand
Minimum value
Energy supply
TRMS True root-mean-square value
Σ
HT
Meter (high tariff)
RMS
Root-mean square value (e.g.
fundamental or harmonic content only)
∅
Average value
(arithmetic mean-value)
