WebTDD (I) = Total Current Demand Distortion is Calculated harmonic current distortion against the full load (demand) level of the electrical system. At the full load TDD (I)=THD (I). So TDD gives us better insight about how big impact of harmonic distortion in our system. For example we could have very high THD but the load of the system is low. WebTOTAL HARMONIC DISTORTION (THDv & THDi) The total harmonic distortion in voltage (THDv) and current (THDi ) is the square root of the sum of squares of the individual harmonic voltage from harmonic order 2 & onwards ( Higher-order may be neglected as their magnitude is low ) ...
