Electromagnetic compatibility (EMC) - Part 4-14: Testing and measurement techniques - Voltage fluctuation immunity test for equipment with input current not exceeding 16 A per phase (First revision) (IEC 61000-4-14:2009, IDT)
MS IEC 61000-4-14:2012
Status : 1st Revision
Format : PDF

This Malaysian Standard is a basic electromagnetic compatibility (EMC) publication. It considers immunity tests for electrical and/or electronic equipment in their electromagnetic environment.
....Read more Only conducted phenomena are considered, including immunity tests for equipment connected
to public and industrial power supply networks.

This part aims to establish a reference for evaluating the immunity of electric and electronic
equipment when subjected to positive and negative low amplitude voltage fluctuations.

The voltage fluctuations considered by this standard do not include flicker, which is a physiological phenomenon due to lighting luminance fluctuations.

This Malaysian Standard applies to electrical and/or electronic equipment that have a rated input current up to 16 A per phase. It does not apply to electrical and/or electronic equipment connected to d.c. or a.c. 400 Hz distribution networks. Tests concerning these networks will be covered by
other standards.

Electromagnetic compatibility (EMC) - Part 4-15: Testing and measurement techniques - Flickermeter - Functional and design specifications (First revision) (IEC 61000-4-15:2010, IDT)
MS IEC 61000-4-15:2012
Status : 1st Revision
Format : PDF

This Malaysian Standard gives a functional and design specification for flicker measuring apparatus intended to indicate the correct flicker perception level for all practical voltage fluctuation wave ....Read more forms. Information is presented to enable such an instrument to be constructed. A method is given for the evaluation of flicker severity on the basis of the output of flickermeters complying with this standard.
The flickermeter specifications in this Malaysian Standard relate only to measurements of 120 V and 230 V, 50 Hz and 60 Hz inputs. Characteristics of some incandescent lamps for other voltages are sufficiently similar to the values in Table 1 and Table 2, that the use of a correction factor can be applied for those other voltages. Some of these correction factors are provided in the Annex B. Detailed specifications for voltages and frequencies other than those given above, remain under consideration.  

The object of this Malaysian Standard is to provide basic information for the de Close

This Malaysian Standard specifies immunity requirements for apparatus intended for use by Electricity Utilities in the generation, transmission and distribution of electricity and related telecommunic ....Read more ation systems. The locations covered are the power stations and the substations where apparatus of Electricity Utilities are installed. 

Immunity requirements are given for the frequency range 0 Hz to 400 GHz, but only in respect of electromagnetic phenomena for which detailed test procedures, test instrumentation and test set-up are given in existing MS IEC standards.

The immunity requirements are suitable for satisfying the particular needs related to the functions and tasks of equipment and systems, for which reliable operation is required under actual electromagnetic conditions; in this respect, this standard establishes performance criteria for the different functional requirements.

Different requirements are given for equipment to be installed in power stations and substations. Close

The primary objective is to provide guidance to system operators or owners on engineering practices which will facilitate the provision of adequate service quality for all connected customers. In addressing installations, this standard is not intended to replace equipment standards for emission limits. 

It does not address how to mitigate disturbances, nor does it address how the capacity of the system can be increased. Since the guidelines outlined in this standard are necessarily based on certain simplifying assumptions, there is no guarantee that this approach will always provide the optimum solution for all flicker situations. The recommended approach should be used with flexibility and engineering judgment as far as Close
