What Is IEEE-519?

by MTE Admin | Apr 13, 2018 | Harmonic Mitigation (Line Side Issues & Solutions)

IEEE-519 is a system guideline for setting limits on voltage and current distortion. The Institute of Electrical and Electronics Engineers (IEEE) is a non-profit professional association dedicated to advancing technological innovation related to electricity. IEEE is...

What Are Active Harmonic Filters?

by MTE Admin | Apr 13, 2018 | Harmonic Mitigation (Line Side Issues & Solutions)

What are active harmonic filters? Active harmonic filters are parallel filters (which means the current doesn’t go through the filter) that are used to reduce, or mitigate, harmonics to tolerable levels as defined by IEEE-519.  Active filters use a set of transistors...

What Are Passive Harmonic Filters?

by MTE Admin | Apr 13, 2018 | Harmonic Mitigation (Line Side Issues & Solutions)

Passive harmonic filters are series filters (which means that current goes through the filter) that are used to reduce, or mitigate, harmonics to tolerable levels as defined by IEEE-519. Passive filters use the following items to ‘filter’ (or clean) the current wave:...

What Is A Harmonic Filter?

by MTE Admin | Apr 13, 2018 | Harmonic Mitigation (Line Side Issues & Solutions)

A harmonic filter is a device that reduces, or mitigates, harmonics to tolerable levels. They are commonly used to lower harmonic distortion to the levels detailed in IEEE 519, the IEEE Recommended Practice and Requirements for Harmonic Control in Electrical Power...

What is Harmonics in an Electrical System?

by MTE Admin | Apr 13, 2018 | Harmonic Mitigation (Line Side Issues & Solutions)

Harmonics in its simplest form is quite simply distortion, which can negatively impact an electrical system. From a technical perspective, harmonics can be best described as the shape or characteristics of a voltage or current waveform relative to its fundamental...

What are the Effects of Harmonics?

by MTE Admin | Apr 13, 2018 | Harmonic Mitigation (Line Side Issues & Solutions)

A power system’s ability to perform at optimal levels is compromised when harmonic distortion enters the system. It creates inefficiencies in equipment operations due to the increased need for power consumption. The increase of overall current required creates higher...
