Without looking at your data, this smells like:

Pij=: -/~@[ % ]

which you use as:
   phase Pij lineReactance

Here, phase is assumed to be 1 dimensional and lineReactance two
dimensional and square.  And phase -:&# lineReactance should always be
true.

I did not try this on your example data since I do not know what the
result would be.

I will note that you are dividing by zero, which is worrying.
