This corresponds to the wiring of individual office rooms to use one (or more) of three different phases. precision as reported by ntpq -c rl is −20, yielding a theoretical timing accuracy of 0.95 μs. The real- world delay, offset, and jitter values of ntpq -p show an average of...
Figure 2: CLEAR current sensors installed in the electric cabinet. The open-loop Hall-effect sensors employ multiple turns of the mains wiring to increase the usable output signal. A small connection board distributes supply voltage and output signals. All changes and alterations were authorized and...
