馬來西亞既電有好多種,市電即住家及商業用途 1ø 240V
3ø 415V +5% -10% & 50Hz ± 1%
至於工業電如下
Voltages
The transmission voltage networks are 500kV, 275kV and 132kV, whilst the distribution voltages are 33kV,
11 kV and 415/240 Volts. However, in the case of certain parts of Johor & Perak the distribution voltages may
also include 22kV and 6.6kV.
Supply Frequency
The supply frequency is 50Hz ± 1%.
Earthing System
High Voltage and Extra High Voltage
• 3 phase configuration
• solidly earthed or impedance earthed
• overhead lines and underground cable are used extensively for high and extra high voltage distribution
Low Voltage 415/240V
• 3 phase 4 wire system
• neutral point solidly earthed mixture of overhead lines, underground cables and aerial insulated cables
• mixture of overhead lines, underground cables and aerial insulated cables
Some of the international standards that explain the power quality phenomenon are:
IEC 61000-2-1: Definition of electromagnetic compatibility (EMC)
MS IEC 61000-2-4: Compatibility levels in industrial plants for low frequency conducted disturbances.
MS 1760: Guide on voltage dips and short interruptions on Public Power Supply System.
MS IEC 61000-4-11: Voltage dips, short interruptions and voltage variation immunity tests for equipment less that 16 Amp.
IEC 61000-4-34: Voltage dips

如果有來馬來西亞記得搵我呀

有D工業需要用到3300V同6600V就要向電力公司買11000V來自己變,仲有輕快鐡同地鐵(一種好像火車既交通工具)係用720V DC,單軌火車用三相720V,電動火車用單相25000V,馬來西亞就係無電車(香港就有電車)
