scope:
This European Technical Report applies to newly manufactured static watt-hour meters intended for residential, commercial and light industrial use, of class indexes A, B and C, for the measurement of alternating current electrical active energy in 50 Hz networks. It specifies particular requirements and immunity test for direct connected and transformer connected electricity meters as an extension for EN 50470-1 and EN 50470-3. The tests are designed to achieve immunity against disturbing currents of up to 2 A (2 kHz-30 kHz) and up to 1 A (30 KHz-150 kHz) for direct connected meters and 2 % Imax (2 kHz-30 kHz) and 1 % Imax (30 KHz-150 kHz) for transformer connected meters.
