Electrical Testing Solutions
Harmonic studies are performed to determine harmonic distortion levels and filtering requirements within a facility and to determine if harmonic voltages and currents are at acceptable levels. Field measurements and computer simulations are used to characterize adjustable-speed drives (ASDs) and other nonlinear loads and simulations are then performed to determine the filter specifications and effectiveness. The application of harmonic filters will significantly alter the frequency response of the power system. An evaluation of the harmonic voltage and current limits, (e.g., IEEE Std. 519) is completed to determine the effectiveness of the proposed filter installation.

Entes Elektronik
ENTES Harmonic Filter Reactors are used in serial connection with capacitor banks in power factor correction units. By using these types of detuned reactors it is possible to increase the capacitor impedance against harmonic currents and to keep the resonance frequency under the frequencies in which main harmonic currents occur by shifting the resonance frequency.

CLT10 - Danbridge a/s
Defective components are not only unreliable, they are also non-linear. Therefore, effective quality control can be carried out by measuring the distortion of a pure sinewave current through the component. The Danbridge CLT System determines the distortion on the 3rd harmonic, and takes this as an indicator of the reliability and quality of the component. By measuring a component's nonliniarity up to the median value of distortion in a batch of components it is possible to quickly determine pass or fail of the component.

HXI, llc
The HHM series of broadband harmonic mixers covers full waveguide bands from 26.5to 110 GHz. The mixers utilize a low loss finline structure mated to a GaAs Schottky beam lead diode for minimum conversion loss and maximum bandwidth. The millimeter wave RF frequency is down converted (using a lower microwave LO frequency) to an intermediate frequency (IF) which can in turn interface with a spectrum analyzer, frequency counter, etc.

Osborne Transformer Corp.
Osborne designs harmonic trap inductors to work in conjunction with capacitors in power systems to prevent specific line-frequency harmonics from flowing back to the power source (point of common connection). This power quality design approach prevents harmonic currents from flowing to the main facility power system and/or to the utility power system. The Osborne system also reduces unnecessary power losses and power-system pollution.

HBF-T - Lifasa - International Capacitors, SA
HBF-T filters are designed to block the 3rd harmonic, reducing the neutral currents in three-phase installations where there are installed harmonic generating loads connected between phase and neutral. It is basically passive filters based on a parallel combination of inductance and capacitor.

FMLF 7% - Lifasa - International Capacitors, SA
These LIFASA capacitors are designed to be connected in series with INR or INA reactors, and thus form a harmonic filter tuned to a frequency of 189 Hz (lower than the first harmonic present in the network). The nominal powers of the filters indicated in the table are obtained by being connected to the reactors.

AC2000A - Laplace Instruments Ltd.
The Laplace Harmonics and Flicker analyser provides the user with a complete system for testing product compliance with IEC61000-3-2 and IEC61000-3-3. Quick and easy to use, the built-in screen provides a clear pass/fail indication of compliance status, plus a full listing of results for each harmonic, in either tabular of bargraph format. The instrument is properly configured to cope with fluctuating harmonics. The Flicker mode provides proper measurement of short term and long term parameters, using algorithms specified in IEC61000-4-15. In addition, inrush current measurements can be automated such that the product under test can be automatically cycled on/off with user entered time profiles.

11970-Series - Keysight Technologies
The 11970-Series waveguide mixers are general-purpose harmonic mixers employing a dual-diode design to achieve flat frequency response and low conversion loss. These are achieved without external dc bias or tuning stubs. Manual operation and computer-controlled hardware operation are simplified because mixer bias and tuning adjustment are not required.
