The search tool seems useless on my IPad so forgive me for asking something that has likely been answered before. Why is voltage drop restricted to 3% while other loads are allowed 5%?

The original cyclocontrol system involves changing the waveforms near the zero-crossings
In contrast Zellweger systems (still used in Oz) superimpose a continuous audio tone of a few volts RMS onto the mains - 1050Hz is one of a number of carrier frequencies used in different places.
