on grid voltage, but leave the underlying grid frequency itself unaffected. The safety reset controller is an
off-the-shelf microcontroller much smaller than the one used for the meter's main application controller. It measures
grid frequency from a voltage waveform acquired using its internal analog-to-digital-converter (ADC) directly connected
to the mains voltage input through a resistive divider chain. The use of an off-the-shelf microcontroller keeps the
implementation overhead of our solution very low in both per-unit and engineering cost.
to the mains voltage input through a resistive divider chain. By using of an off-the-shelf microcontroller we keep the
implementation overhead of our solution low in engineering cost compared to an ASIC. By keeping its firmware small, we
can use a simpler and less expensive microcontroller, keeping per-unit implementation cost low.
