We are pleased to announce that we have completed the relocation of our new corporate headquarters in Odessa, Florida.

Our new address is 2404 Merchant Avenue, Odessa, Florida 33556.
Our toll free 888-539-7712 number remains the same.
Our general local number is 727-478-7284 and our new fax number is 727-478-7289.

PQI is also pleased to announce that our new website has been launched at PowerQuality.net or PowerQualityInternational.com.

PQI received a prototype Transformer Excitation & Impedance Losses Measurement Instrument from Omega Magnetics Engineering for evaluation. In addition to conventional power and harmonic measurements, the new instrument will also measure a transformer’s Excitation Losses and Load Losses, then calculate its Energy Efficiency, under linear or any nonlinear load condition. This electronic measuring instrument is based on the ‘Voltage and Current Difference, Loss Measurement Method’, which has been discussed in a number of recent IEEE papers and the measuring instrument that was developed by PQI for its HarMitigator™ Technology Demonstration Vehicle.

Omega Magnetics Engineering is currently developing a line of precision portable and panel instruments that will have a losses measurement accuracy of ±1.3% and an efficiency calculation accuracy of ±0.033%. The portable instrument should be of interest to harmonic mitigating and K-Rated transformer manufacturers, and field service engineers (i.e. NETA member companies), since there is presently no accurate alternative measuring instrument.

PQI introduces next generation software. The PQI Calculator™ summary page now includes graphical displays of Total Losses and Transformer Efficiencies for a single transformer or for any two transformers which are being compared. The calculation of losses and efficiencies has also been refined.

The new calculator now allows one to compare transformers with different kVA ratings, secondary voltages, harmonic profiles and load profiles, including operation cycles at no load. In addition, transformers with or without zero-sequence harmonic flux cancellation windings can now be compared more accurately.

PQI introduces a Transformer Metering System for LEED® Rated Green Buildings. This factory installed metering system includes a ‘Revenue Class’ power meter, current transformers, characterized to 0.1% accuracy, and HRC fused voltage connection (with voltage transformers, when necessary) , all of which are installed within the transformer enclosure.

The application of ultra-efficient transformers, which exceed NEMA and CSA efficiency requirements, provides the means to obtain a LEED® EA Credit 1 – ‘Optimized Energy Performance’. Equipping these ultra-efficient transformers with LEED® compliant integrated metering systems provides the means to obtain an EA Credit 3 – ‘Enhanced Commissioning’ and an EA Credit 5 – ‘Measurement and Verification’, the maximum available for a transformer installation. With respect to EA Credit 5, this metering system is capable of integrating into virtually any building management system.

PQI congratulates Dr. Aleksander Damnjanovic, our Director of Research & Development, on receiving his PhD from Tshwane University of Technology, Pretoria, South Africa. The title of his thesis was ‘Modeling Transformer Nonlinearities, taking Hysteresis into Account’.

Aleksander was the team leader in the development of The PQI Calculator™ software and the Voltage and Current Difference, Loss Measurement Method Instrument, which was developed by PQI for its HarMitigator™ Technology Demonstration Vehicle.

PQI supplies two 1500/2000kVA, 12470:480V Power TransFilters™ to the Wynn Hotel & Casino in Las Vegas, Nevada and I₀Filters™ for all panels that supply gaming machines at the Wynn Hotel & Casino in Macau, China. PQI has supplied a substantial number of filters for Wynn’s casinos over the past few years.

PQI completes the development and fabrication of a Voltage and Current Difference, Loss Measurement Method Instrument, which is based on work done at the University of Colorado at Boulder (USA) and the Institute of Electrotechnics, University of Cagliari (Italy), and the fabrication of PQI HarMitigator™ Technology Demonstration Vehicle.

The van is equipped with a conventional 15kVA Distribution Transformer, an ultra-efficient 15kVA Type DV Distribution TransFilter™, a 5.25kVA (35% of 15kVA) linear and nonlinear Load Bank, a 100’ and 200’ three-phase, four-wire, 20A Branch Circuit, a Fluke® Power System Analyzer and a Voltage and Current Difference, Loss Measurement Method Instrument.

 

 

The vehicle will be used to demonstrate the difference in No-Load and Load Losses and Energy Efficiency under both linear and nonlinear loading. By connecting either transformer to either load bank, we will be able to demonstrate the negative impact nonlinear loads have on branch circuit losses and voltage distortion at the loads.

First to use a sophisticated computer program that is in compliance with IEEE Std. C57. 110-1998. The program allows our engineers to calculate any transformer’s nonlinear losses and efficiencies based on its linear losses and efficiencies, which is based on a specific harmonic current profile and load.

The PQI Calculator™ will compare the performance of any two transformers and calculate a payback and return-on-investment.

PQI completes the development of the HarMitigator™ product line. These products include dry type Power TransFilters™ to 15MVA, 35kV Class for all load types, cast coil Power TransFilters™ to 7MVA, 35kV Class for all load types, dry type Distribution TransFilters™ for all load types, 240V Power Distribution Units for data centers, dry type I₀Filters™ and Mini-Z™ filters for zero-sequence harmonics. This selection of harmonic mitigating products gives PQI the ability to solve virtually any power system compatibility problem.

PQI completes the design and installation of electromagnetic Zero-Sequence Harmonic Filters, which shunt zero-sequence harmonic currents from 120/208V three-phase, four-wire sub-systems. Our search of the literature indicates that this IBM Toronto installation is the first of it kind.

I₀Filter™ products provide an alternative to de-rating conventional distribution transformers, applying K-Rated distribution transformers or increasing the wire size of feeder circuits’ neutral conductors, in an environment that is rich with zero-sequence harmonic currents.

PQI completes the design and installation of the very first Harmonic Mitigating Transformer that cancels zero-sequence harmonic flux within its secondary windings, eliminates zero-sequence flux in its core and zero-sequence current in its primary winding and acts as a phase-current balancer. The transformer also cancels positive- and negative-sequence harmonic current. The transformer is applied at the output of a large UPS, which supplies the critical loads in a data center.
