AS 62054.11:2018 pdf download.Electricity metering equipment (a.c.)—Tariff and load control Part 11: Particular requirements for electronic ripple control receivers (IEC 62054-11:2004 (ED.1.1), MOD).
If the bursts are applied while the receiver is in a quiescent state, it shall be verified that the receiver does not start as an effect of the bursts. For this purpose, 3 s after the bursts have been applied a message is transmitted with operate voltage Uf. The output elements shall operate correctly according to the commands of the message.
If the bursts are applied in such a way that bursts occur during a transmission cycle, it shall be verified that bursts did not impede the operation capability of the receiver. For this purpose, the receiver is started by a message with the operate voltage (If. It shall be verified that, despite the application of the bursts, no wrong operation occurs. In cases where the disturbance coincides with the start bit or an information pulse related to this command, or is adjacent to it, it is accepted that no operation is carried out. In all other cases, the command must be carried out.
However, in non-operation or even with some kinds of codes, a malfunction may be accepted if the transient coincides with a pulse position or is adjacent to it.
The application of the bursts shall not affect the internal timers. It shall be verified that after the test, operations carried out based on such internal timers are correctly executed.
7.6.6 Test of immunity to conducted disturbances, induced by r.f. fields
In addition to IEC 62052-21, the following applies.
The receiver shall be tested in a quiescent state and during transmission cycles.
If the conducted r.f. disturbances are applied while the receiver is in a quiescent state, it shall be verified that the receiver does not start as an effect of the conducted r.f. disturbances. For this purpose, 3 s after removing the conducted r.f. disturbances, a message is transmitted with operate voltage Uf. The output elements shall operate correctly according to the commands of the message.
If the conducted r.f. disturbances are applied during a transmission cycle, it shall be verified that the conducted r.f. disturbances did not impede the operation capability of the receiver. For this purpose, the receiver is started by a message with the operate voltage Uf. It shall be verified that, despite the application of the conducted r.f. disturbances, no wrong operation occurs.
The application of the conducted r.f. disturbances shall not affect the internal timers. It shall be verified that operations carried out on the basis of such internal timers are correctly executed.AS 62054.11 pdf download.
