Alternating Current

JeremyDover and I would like to present the next puzzle in our Entropic Lines series, which explores the interactions between entropic lines and Kropki.
Rules
Normal sudoku rules apply.Entropic lines: Any set of three sequential cells along an entropic line must contain a low digit (1-3), a middle digit (4-6), and a high digit (7-9). Digits may repeat on a line, if allowed by other rules.
Note: The differing color on lines is simply to visually distinguish the lines which cross; other than the cell they share, the digits on one line have no affect on the other.
Kropki rules apply: Cells separated by a white dot must contain consecutive digits. Cells separated by a black dot must have digits in a 2:1 ratio. Not all possible dots are given, so there is no negative contraint.
This is puzzle #3 of the entropic lines introductory series.

Solution code: Row 4 (from left) and column 4 (from top - 18 digits in total):

Very fun puzzle! I hadn't seen this variant before but I really enjoyed it and how it interacted with the Kropki dots.
