Impact of Malaysian EMF Standard on electrical line design and performance

Overhead transmission lines generate electric and magnetic fields at power frequency. These fields play an important role in transmission line design and occupational safety standards compliance. Typically, the EMF exposure limits for electrical line design in Malaysia is based on established international or national standard of developed countries due to lack of local standard on EMF exposure limit. Malaysian Standards has published new requirement for electric and magnetic exposure limit recently. This paper presents the impact to the electrical line design and performance in meeting EMF emission limits based on the new standard. The associated financial impact, corona related environmental impacts and lightning performance of the lines are evaluated and discussed.
