1. A system for mapping an array of electrical components comprising:
a plurality of electrical components, each of the electrical components in the plurality distinct from each other, each of the electrical components spaced apart from each other, the electrical components arranged in at least one array and connected to at least one other electrical component;
a frequency generator, the frequency generator configured to generate a frequency signal different from a base operating frequency, the frequency generator configured to send the signal to each of the electrical components in the plurality;
a plurality of sensors, each of the plurality of sensors configured to measure, at the same time, a voltage or current at each of the plurality of electrical components, the voltage or current reflecting the amplitude of the cycling frequency signal sent by the frequency generator and received at the electrical component being measured by the sensor; and
a system analyzer configured to consider a plurality of the voltages or currents measured by the plurality of sensors and attributable to different electrical components in the plurality of electrical components and determine a relative position of electrical components with respect to other electrical components,
wherein during a mapping cycle, the frequency generator generates frequency signals transmitted over the system in an ascending frequency order and a descending frequency order,
wherein the system analyzer considers responses to the frequency signals from each of the plurality of electrical components, groups the electrical components according to shared trajectories of their responses, and assigns each of the plurality of electrical components to a branch circuit based upon the groups.
