TDD calculations

TDD (total demand distortion) evaluates the harmonic currents between an end user and a power source.

The harmonic values are based on a point of common coupling (PCC), which is a common point where each user receives power from the power source.

The meter uses the following equation to calculate TDD:Where ILoad is equal to the maximum demand load on the power system.
