IEC EN 62054-11 Electricity Measurement (AC) - Tariff and Load Control - Part 11: Special Requirements for Receivers with Electronic Surge Control

EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of IEC EN 62054-11 testing. IEC EN 62054-11 specifies specific requirements for type testing of newly manufactured receivers with internal electronic surge control for receiving and interpreting pulses of a single audio frequency superimposed on the voltage of the electrical distribution network. In this system, the mains frequency is usually used to synchronize the transmitters and receivers. Neither control frequency nor coding is standardized in this standard.

This standard does not place any requirements for structural details inside the receiver. Where surge control functionality is integrated into multifunctional electrical measuring equipment, the relevant parts of this standard apply.

Test levels are considered minimum values ​​to guarantee proper operation of equipment under normal operating conditions. For specific applications, other test levels may be required and must be agreed between the user and the manufacturer.

Surge controlled receivers are components of a remote control system that allows multiple receivers to operate simultaneously from a central point. The signal generally used for this purpose is an audio frequency voltage superimposed on the mains frequency and coded as pulses, capable of providing a number of control functions. Frequency modulation, deformation of mains frequency, etc. Other types of signals can also be used, such as These signals are propagated from the injection point to the receiving sites through the electrical supply network.

The requirements of this standard are not limiting. If this is absolutely unavoidable, a user may add additional technical requirements to the specification. The technical requirements and tests relate to the overall operation of the receiver. The method of operation of the functional elements is not specified. However, these requirements and tests may be the subject of additional technical agreements.

Surge control systems are auxiliary equipment for network operation. Their design is determined by network characteristics and other factors. Today, the rapid development of power electronics equipment leads to a parallel increase in the amount of harmonic distortion in the supply voltage. The harmonic levels specified in this standard take this development into account. They should be considered as recommended values ​​for designing and testing receivers, not as allowable values ​​on the network. These recommended levels can be adapted to the specific characteristics of the networks in question.
