Inductors
 

POWER ENGINEERING INDS. (PE) is particularly proud of its expertise in inductor design and manufacturing. For over 40 years PE has been supplying inductors, reactors and chokes for a myriad of applications to countless industries. The range of sizes and types of these units designed and manufactured by PE is truly remarkable as it covers the some of the following applications:

 

Iron Core
Air Core
Toroidal Core
Micro Henry to Henry
Milli Amps to Killo Amps
Volts to Killo Volts

  • Rapid Transit
  • High Energy Physics
  • Inverter Systems
  • Industrial Power Supplies
  • AC load Banks
  • Power Conditioning
The range of inductor products that PE has supplied since 1963 is truly outstanding: inductances up to several Henries, currents up to 250,000 Amps, voltages up to 150,000 Volts, BIL’s up to 300,000 Volts, air cooled, water cooled, SF6 cooled, air core, iron core, toroidal cores and many other features. But equally as important is the remarkable record of quality that PE has been able to demonstrate and sustain over the years. Witness the reputation that PE has built up with extremely demanding customers.
 

 


Rapid Transit

PE's inductors can be found in virtually every transit authority systems in the country. The versatility of the designs to adapt not only to the various authorities’ requirements, but also to the severe environmental conditions, is truly a remarkable testament to PE’s flexibility. In addition strict adherence to AREMA, IEC and ANSI standards is required.

 
  • Air core and iron core Inductors have been built with inductances of up to 15 mH and currents up to 5000 Amps. A variety of materials have been employed such as copper and aluminum wire and foil, Litz wire, silicon steel and amorphous cores. Worthy of special mention is the fact that PE has been able to achieve extremely low magnetic field emissions on its air core inductors due to a proprietary especial shield design. These units have been designed for cooling by natural convection or forced air cooling
  • Air core and iron core for auxiliary systems in traction systems. These units have been built with inductances up to 5.0 Henry and currents up to 500Amps. These units have used similar materials and construction techniques as the traction inductors with the added difficulties of being able to accommodate higher frequencies (up to 100kHz) of operation.
  • Swinging chokes for auxiliary systems. These devices contain two or more gap sizes to provide different inductances at different current levels.

  • Air core commutating (di/dt) Inductors manufactured for very high current, short circuit applications to 130kAmps with high frequency harmonics.

Fusion Research

The uniqueness in applications for fusion machines lies in the fact that due to the pulsed nature of operation these units not only have to perform electrically but must have a superior mechanical integrity to be able to sustain extremely high current peaks of operation.
  • Current limiting inductors. Mostly of air core design, these units have been built to meet an endless variety of operating conditions from dc currents to very high frequency ac currents.

  • Filter inductors for dc power supply systems. Mostly of iron core design, these units have been designed to accommodate very high dc currents with superimposed ac currents.

  • Harmonic filter inductors. These devices have always been a challenge to design and build since they have to meet very exact parameters of frequency and current. Their construction many times involves the use of special cores, multiple gaps, high frequency conductors such as Litz wire and other unique engineering and manufacturing techniques.

Inverter Systems

These systems which include fuel cells, ac batteries, wind, solar and magnetohydrodynamic (MHD) generators introduce their own unique brand of requirements to the inductor units they utilize. These requirements include variable currents and frequencies and a variety of environments.
