| Illinois Wastewater Treatment Plant Renovation Category: Case Study Date: June 27, 2022 |
Featured ProductsHGP HarmonicGuard Passive Harmonic Filter with PQconnectProblemNew state requirements for phosphorus removal meant that the wastewater treatment facility in St. Charles, Illinois had to be upgraded to accommodate the change. This meant that the facility needed to convert to a three-stage A2O system, with aerobic, anoxic, and anaerobic zones for biological phosphorus removal. They needed to add a new internal recycle pump station, a primary sludge fermenter, and replace sludge and biogas storage tanks. In the process, they rehabilitated the digesters and biogas system as well. Some of the changes required adding non-linear load variable frequency drives which added harmonics to the system.SolutionThe addition of HGP Passive Harmonic Filters on non-linear VFD loads will reduce harmonic distortion to less than 5%. Renovations like this typically include additional stages of pumping that require VFDs, and thus additional harmonics for the entire plant. Applying passive filters to the new VFDs is an easy and inexpensive way to get the facility back to a low level of harmonic content, which is ideal for the equipment in the entire plant. The article in Treatment Plant Operator magazine, Upgrading to a Bio-P Process Required Open Communication and a Proactive, Patient Approach at Wastewater Facility, by Jim Force, describes in detail how the wastewater facility had to be upgraded, and is the source of the information and picture for this case study. |

| Alabama Reverse Osmosis Stations Category: Case Study Date: June 27, 2022 |
Featured ProductsHGA HarmonicGuard Active Harmonic FilterProblemThe renovation of two reverse osmosis stations at a wastewater treatment plant in Alabama required harmonic mitigation. Each station’s total non-linear load, and resulting harmonic distortion, required 670 corrective amps. Without a solution the distortion would potentially cause the equipment to go off-line due to nuisance tripping. The owner considered the addition of multiple 300 amp active filters in parallel, equating to three units per station. Due to space and cost constraints, the customer struggles with this solution.SolutionTCI offers the largest single-unit amp rated active filters in the market, an ideal solution for this application. The owner installed one 700 amp TCI active harmonic filter per station. The benefits included significant cost savings over alternative solutions and the smaller footprint allowed the installation to proceed without other costly modifications. The stations now meet the IEEE-519 requirements eliminating the nuisance tripping caused by harmonics. |

| Southeastern Aquarium Category: Case Study Date: June 27, 2022 |
Featured ProductsHGA HarmonicGuard Active Harmonic FilterProblemThe pumping requirement was immense at one of the largest aquariums in the world, in the southeastern region of the United States. The large number of pumps and horsepower required to move so much water resulted in enough VFD load to require significant harmonic mitigation. An initial set of active harmonic filters from another manufacturer was installed for the application. Immediately there were problems between the active filters and the VFDs. The drives were tripping due to an inrush of current from the active filters coming online. The pumps were not able to move water with the drives offline due to the harmonic filters.SolutionThe facility was retrofitted with TCI HGA active harmonic filters. The HGA is designed with a pre-charge circuit that allows for the filter to slowly come online, which allows the VFDs to operate continuously. The pre-charge circuit enables the harmonic filters to softly engage with the system. The operation is not affected by any inrush surges from the HGA active filters but receives the benefit of the harmonic mitigation. |

Drive Impedance and Passive Filters Category: Documents, Tech Paper Date: September 19, 2018 |
While most variable frequency drives (VFD) use a built in DC choke or AC line reactor, some lower HP drives have no built-in impedance. Passive filters are an effective solution to filter harmonic currents produced by 6-pulse VFDs and reduce source current total harmonic distortion (THD) to 5% or less. | Download |

Effective Harmonic Mitigation with Active Filters Category: Documents, White Paper Date: August 15, 2018 |
Industry standard three‐phase variable speed drives draw harmonic currents from the three phase voltage source. These harmonics can cause overheating and premature failure of power system equipment. An active filter is an effective way to filter the harmonic currents required by VFDs and eliminate the harmonic currents and voltages from the AC source. | Download |
