AS60038, was published in Australia on 23rd January 2000 to</font><font
face="Times New Roman, Times, serif"> replace the previous 240V
standard. This requires</font><font face="Times New Roman, Times,
serif">, under normal service<br>
conditions, that the</font><font face="Times New Roman, Times,
serif"> voltage at the point of supply should not differ from the
nominal voltage of 230/400V by more than +10%,-6%. <br>
Voltage drop within a customer's premises may reduce this by
another 5%, the maximum permissible under AS/NZS 3000, known as
the Wiring Rules.<br>
Essential Energy therefore say that the total variation can be as
wide as +10%, -11%. Essential Energy realises that this voltage
range may cause issues with 240V equipment and they, therefore,
have adopted the range of 230V, +10%, -2%, which aligns very
closely with the old 240V standard. When I was the Supply
Irregularity Officer with a County Council (not Essential Energy)
the standard was 240V, ±6%, or 226V-254V. I know that other states
had different standards at the time, and maybe they still do.<br>
<br>
The current Essential Energy "standard" of 230V, +10%, -2%, is
within AS60038 requirements, and returns a voltage range of
253V-225V. The AS60038 percentages return 253V-216V. <br>
<br>
During my time in the position of SIO the nominal HV supply was
11,000V, and that tap setting was chosen on distribution
transformers. Under unloaded network conditions the LV would be at
near the top allowable figure of 254V, and network load would
reduce that figure.<br>
<br>
Whilst the "nominal" voltage may be 230V according to AS60038, in
practice, it appears little (nothing?) has changed since the 240V
standard. <br>

Previously when 240, it was ± 10% so 264 to 216<br>

Mine is solar powered - radio and the computer setup
The planned one is for a place where the power is provided by my son's
