Hi,

Request your help in calculating the Total Demand Distortion (TDD) % of current and voltage from THD values already being pumped by my meter (EM6400)every few seconds. Since THD is Harmonic components divided by Full load current, i need clarification how to calculate the harmonic components from the data. I have full load current based on my overall machine electrical rating. Please advise.
Thanks in Advance

Hi sir,
My deep apologies for delayed response and Thanks for your feedback. In our case we receive only THD for each of current values.How to calculate only the Harmonic component absolute values from the THD % of each of current values. Any help on this specific point will be of great help. Thanks in advance.
