PQI TPM Integrated Transformer Performance Meters

Posted in Energy Efficient Transformers

PQI TPM Integrated Transformer Performance Meters
Type TPM Integrated Transformer Performance Meters™ are installed on all PQI e-Rated™ Distribution Class Transformers. In addition to their revenue class metering and data logging capabilities, these integrated meters, with CSA C802.5 compliant software, determine each transformer’s Total Losses and Efficiency under their measured nonlinear loading profiles.

In addition, IEEE Std. C57.110 compliant software also determines each transformer’s No-Load Losses and Load Losses, including its nonlinear ‘Penalty Loss’ component and EPA Environmental Benefits. In its ‘transformer comparison mode’, given the cost of each transformer and the cost of energy, the software will also compare the performance of any two transformers, including A/C costs, and calculate an annual saving, payback and return-on-investment, in a ‘substitution’ or ‘before end-of-life replacement’ scenario.

PQI Air Core Reactor

Posted in Energy Efficient Transformers

PQI Air Core Reactor
Windings are manufactured with aluminum or copper, (strip or shaped conductors in parallel where necessary) arranged on layers or discs with special consideration given to minimize eddy current losses. The insulating materials used during production are always UL listed systems. To suit various applications and environmental conditions PQI Dry Type Air Core Reactors are manufactured using our multiple VPI and Epoxy Impregnation system. For harsh conditions PQI offers Reactors that are solidly cast in epoxy in special molds filled under vacuum.

Reactors can be supplied either as single-phase coils individually supported on insulators or as three phase coils stacked vertically.

A variety of custom enclosure designs are available to shield and protect the reactors magnetically and environmentally.

PQI HQ
A solution for electrical distribution systems that demand stable, reliable power characterized by unparalleled power quality and efficiency. Applications where PQI Type ‘HQ’ Active HarmVAr Filters are often applied include commercial, industrial, institutional, military, mining, municipal, solar, wind turbine and many others.

The PQI Type ‘HQ” Active HarmVar Filter optimizes power system performance by combining the use of proven IGBT technologies with leading edge DFT/FFT algorithms enabling the simultaneous and/or discrete execution of harmonic (VArH) and reactive (VArQ) compensation methods in real-time.

PQI Z and Mini-Z

PQI Z
Type Z e-Rated® I0Filters are highly effective, three-phase, four-wire, passive electromagnetic filters with ultra-low zero-sequence impedances. These filters have been specifically designed to provide a parallel path for all zero-sequence harmonic currents that are generated by phase-to-neutral connected nonlinear electronic loads. Power quality benefits are optimized when filters are installed as close as possible to these electronic loads.

Type Z filters are normally installed at all sub-panels that supply single-phase nonlinear electronic loads via a three-phase circuit breaker. Whether specified at the design stage for new construction or applied in an existing sub-system, these filters are normally sized for potential zero-sequence harmonic current levels. This application philosophy eliminates the need to increase filter capacity as zero-sequence loading increases over time.

PQI SY
Type SY e-Rated® low voltage dry-type isolation transformers exceed all existing and pending energy efficiency requirements. Energy efficiency requirements are determined at 35% of the transformer’s full load (FL) rating. As a result, manufacturers generally optimize their transformers’ efficiencies at approximately 35% FL.

Type SY transformers’ ultra-low Excitation (no-load) Losses provide high efficiency during periods of light-loading (<15% FL). This benefit is achieved by using higher quality, grain oriented silicon core steel in the Unicore™ cores of lower kVA ratings and in the full and step-lap miter-cut cores, with reduced laminations per group, in higher kVA ratings.

Unlike Excitation Losses, which are constant from no-load to full-load, Impedance (load) Losses increase rapidly above 15% FL; particularly when the transformer’s loads are nonlinear. To maintain energy efficiency, Type SY e-Rated® transformers’ peak efficiencies can be matched to anticipated or measured average loading above 35% FL.
