Total Demand Distortion and IEEE 519 2014TDD and IEEE 519 2014_05

Read why checking TDD for IEEE 519 compliance is important for utilities to meet voltage requirements.


IEEE standard 519 defines limits on Total Harmonic Distortion (THD) as well as Total Demand Distortion (TDD) with regards to both voltage and current. Total Demand Distortion is often the most important parameter to check for IEEE 519 compliance, as without each customer staying within limits, it will be difficult or impossible for the utility to meet the voltage requirements. The method for recording the required data and viewing it in ProVision is described here.
