What is good current? It’s a peak number that is stable. We use the peak number to determine our level of current. This is
despite the fact that the receiver has a current measurement indication. Current measurement is performed with two stacked peak antennas, as is digital depth (Figure 11-13).
The cable leaving the transformer is a direct buried bare concentric three phase cable (Figure 14), and our access point is on the shell of the transformer (Figure 15). The transmitter is going to be set to 512 Hz with a current of 20 mA (Figure 16).
