Some electronics regulations require a galvanic isolation boundary 3054 to protect users from high voltages. Here, the galvanic isolation boundary passes through the voltage regulator 3006. In order to pass data and instructions across this boundary, a non-contact transmission device 3014 straddles the boundary. An optical isolator is one example of the non-contact transmission device 3014.
Sensing channels 3030, 3038, and 3042 can be leads going to sensors that are remote from the lines being monitored, or can provide data to controllers from sensors that are affixed to or relatively close to the lines being monitored. In
Control channels 3032 and 3040 are illustrated as passing from controllers to regulators. However, these are functional representations only, not physical circuit representations. As such, these control channels 3032 and 3040 can be implemented in a variety of fashions. In some cases, wireless connections can be used (e.g., radio or optical), while in others, the controllers and regulators can be integrated such that no external leads pass between distinct components.
