....."The inaccurate readings are attributed to the energy meter's
design, together with the increasing use of modern (often
energy-efficient) switching devices. Here, the electricity being
consumed no longer has a perfect waveform, instead it acquires
an erratic pattern. The designers of modern energy meters
have not made sufficient allowance for switching devices of
this kind. When they dismantled the energy meters tested, the
researchers found that the ones associated with excessively high
readings contained a 'Rogowski Coil' while those associated with
excessively low readings contained a 'Hall Sensor'."

I smell lawsuits since the PoCo's have been removing the
old meters en mass....
