This part of IEC 62054 specifies particular requirements for the type test of newly manufactured indoor electronic ripple control receivers for the reception and interpretation of pulses of a single audio frequency superimposed on the voltage of the electricity distribution network and for the execution of the corresponding switching operations. In this system the mains frequency is generally used to synchronize the transmitter and receivers. Neither the control frequency nor the encoding are standardized in this standard.
This standard gives no requirements for constructional details internal to the receiver.
In the case where ripple control functionality is integrated in multifunction electricity metering equipment, the relevant parts of this standard apply.
This standard does not cover the acceptance tests and the conformity tests. Nevertheless, an example of what could be an acceptance test is given in Annex D.
The safety aspect is covered by IEC 62052-31:2015.
The dependability aspect is covered by the documents of the IEC 62059 series.
When using this standard in conjunction with IEC 62052-21, the requirements of this standard take precedence over those of IEC 62052-21 with regard to any item already covered in it.
