According to MS IEC 60038, the requirements of nominal low voltage supply in Malaysia is 240 Vrms or 400 Vrms with variations of +10 % and -6% and the nominal frequency is allowed to fluctuate at ± 1% from 50 Hz. Figure 1 shows a capture of a single phase supply voltage in Malaysia. Examine the waveform under each time zone and determine its compliantness to the standard. Show all relevant calculations.
