# Directive 2014/32/EU of the European Parliament and of the Council of 26 February 2014 on the harmonisation of the laws of the Member States relating to the making available on the market of measuring instruments (recast) (Text with EEA relevance), Division 2: Rated operating conditions

Extent: E+W+S+N.I.

The manufacturer shall specify the rated operating conditions of the meter; in particular:
The values of fn, Un, In, Ist, Imin, Itr and Imax that apply to the meter. For the current values specified, the meter shall satisfy the conditions given in Table 1;
Table 1
For Class B electromechanical meters I min ≤ 0,4 × I tr shall apply.
Class A
Class B
Class C
For direct-connected meters
Ist
≤ 0,05 × I tr
≤ 0,04 × I tr
≤ 0,04 × I tr
Imin
≤ 0,5 × I tr
≤ 0,5 × I tr
≤ 0,3 × I tr
Imax
≥ 50 × I tr
≥ 50 × I tr
≥ 50 × I tr
For transformer-operated meters
Ist
≤ 0,06 × I tr
≤ 0,04 × I tr
≤ 0,02 × I tr
Imin
≤ 0,4 × I tr
≤ 0,2 × I tr
≤ 0,2 × I tr
In
= 20 × I tr
= 20 × I tr
= 20 × I tr
Imax
≥ 1,2 × I n
≥ 1,2 × I n
≥ 1,2 × I n
The voltage, frequency and power factor ranges within which the meter shall satisfy the MPE requirements are specified in Table 2. These ranges shall recognise the typical characteristics of electricity supplied by public distribution systems.
The voltage and frequency ranges shall be at least:
0,9 × U n ≤ U ≤ 1,1 × U n
0,98 × f n ≤ f ≤ 1,02 × f n
power factor range at least from cosφ = 0,5 inductive to cosφ = 0,8 capacitive.
