RTR Energy’s active filter helps to eliminate harmonic distortion from the network and avoid problems that may arise due to poor power quality.
Variable frequency devices, UPS systems, computers and light savings are some of the main causes that raise harmonic distortion above acceptable limits.
High harmonic distortion reduces lifespan and causes low productivity in electrical equipment.
Some unbalanced loads, such as computers, cause excessive current through the neutral, as well as current harmonic distortions corresponding to the third harmonic that flow through the neutral, giving rise to unacceptable voltage levels between neutral and earth and that can lead to malfunctions, and even physical damage to electrical equipment.
For this reason, RTR Energía’s active filter offers a complete solution for those installations where there are dynamic variations in the load due to harmonic distortions, unbalanced loads or single-phase loads with a high level of harmonic distortion in intensity in the neutral. This active filter is connected in parallel to the existing load or to the installation, and measures and analyzes the content of harmonic distortion of the load or of the phases of the installation and injects a current in the network in the opposite direction that compensates for the existing harmonics. As a result of this injection, the existing harmonics are eliminated and the neutral is “unloaded”.
These filters guarantee less than 5% THD I, even in installations where harmonic distortion is very high. Active harmonic filters also aid dynamic power factor correction with 100% inductive and capacitive support.
The system reacts to load changes in less than 25μs.
