I am confused about this figure because some equipments have 230 Volts AC (50 Hz) specified as their operating voltage while some others have 240 V AC (Hz). I practically measured the supplied voltage. It was something like 235 V AC. So I am confused about the standard figure. Is it 230 V AC or 240 V AC ?
Power in the US is 120 VAC +- 5% so 114 to 126 is within tolerances per the maintenance people who were fixing a high voltage at my place. I used to measure 117 at my house. People often say we have 115/230 for our single/double delivery voltages. Most equipment with a range printed on it says 110-125. India presumably is nominally 240.
If you measured the supply you must be in India. Why don't you call the electricity supply people and ask them what their official figure is? You should also ask them within what limits the variation is controlled. The difference in the figure stated on an item of electrical equipment, i.e. 230 vs 240, is irrelevant. They all will have a margin, maybe plus or minus 10 or 15%, within which they will work satisfactorily.
