Can the WT1800/WT1800E measure Total Demand Distortion (TDD)?

Yes, the WT1800 can measure TDD using the following user-defined equation:

ITHD(E1)*IK(E1,OR1)/IL

IL=maximum demand load current. IL should be a constant entered by the customer based on IEEE 519 standards. The above equation is written for element 1.
