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

ELECTROMAGNETIC COMPATIBILITY (EMC) - PART 6-5: GENERIC STANDARDS - IMMUNITY FOR POWER STATION AND SUBSTATION ENVIRONMENTS
MS 61000-6-5:2010
Status : Original
Format : PDF

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

This Malaysian Standard specifies guidance on principles which can be used as the basis for determining the requirements for the connection of fluctuating installations to MV, HV and EHV public power ....Read more systems that produces voltage flicker and/or rapid voltage changes. 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
