Information

Measures the electric power p flowing from 'term_p' to 'term_n' and the total heat inflow q at term 'heat'. The efficiency eta in % is then defined by

  eta = 100*(p - q)/p     if arrow points into the measured component and q <  abs(p)
  eta = 100*p/(p + q)     if arrow points out of the measured component and q <  abs(p)
  eta = 0                 else

Note: Take care about the above definitions if approximations are used in measured components.
In problematic cases use power sensors electrical and mechanical.
