Is Powerline Voltage Always an Integral Multiple of 11?

Click For Summary
SUMMARY

The discussion clarifies that the assertion regarding powerline voltage being an integral multiple of 11 is incorrect. While an example of 11,000V is provided, it is emphasized that powerline voltages are not consistently applied in multiples of 11. The conversation highlights the variability in voltage levels supplied by power companies, which can differ based on regional standards and requirements.

PREREQUISITES
  • Understanding of electrical engineering principles
  • Familiarity with power distribution systems

Why is the supplied voltage in the powerline wires an integral multiple of 11 from the supplier? Example -- That line is 11,000V

The answer is that it is not true. We do not always apply voltage in multiples of 11.
 
Most likely this can only be answered by an "old timer". I am making measurements on an uA709 op amp (metal can). I would like to calculate the frequency rolloff curves (I can measure them). I assume the compensation is via the miller effect. To do the calculations I would need to know the gain of the transistors and the effective resistance seen at the compensation terminals, not including the values I put there. Anyone know those values?
