Non-linear loads generate high levels of harmonic currents. When supplying power to these loads, a special transformer design is necessary. FH Transformers use special winding techniques to minimize eddy current losses generated by harmonics. The harmonics of a given load are represented by K-factor. The larger the K-factor, the more harmonics are present. Linear loads have a K-factor of 1; switch mode power supplies typically have a K-factor as high as 20.


Features

  • 150°C Rise, 220°C insulation. UL & CUL Listed
  • Optimal Ventilation - Horizontal and vertical spacers are
  • strategically positioned in the windings to brace the winding layers and allow maximum ventilation.
  • Primary taps: +2, -4 x 2.5%
  • Rugged Enclosure - Strong steel enclosure with slotted hex head screws on cover for easy and fast wiring access. Outward facing foot mount brackets provide for easy forklift access and mounting.
  • Vibration Dampening - The core and coil assembly is anchored to the enclosure through a vibration dampening system to reduce noise levels.
  • Wiring Compartment - Large front facing wiring compartment for easy access. Terminals are sized to carry the full current capacity of the transformer. (Recommended 90°C wire)

With today's modern electronic, electrical components and circuitry constantly changing, the demand is forced upon the electrical power industry to produce and supply a clean source of electrical energy.

The extensive utilization of solid state power conversion technologies has created new problems for the power industry and power engineer designer. This technology, called Switch Mode Power Supply (SMPS), consists of various types of solid state switching elements. These switching elements are solid state devices such as: SCR's DIAC's, transistors and capacitors. These switching devices are in computers, copy machines, fax machines, telecommunications equipment solid-state drives and controls, energy-efficient lighting ballasts, and numerous types of DC-Power Loads. These solid state elements continuously switch on and off producing non-linear or non-sinusoidal wave shapes in the current supplied from the energy source.

While a linear load uses current from the AC source continuously over the sinusoidal cycle, a non-linear load (such as the SMPS) uses current in large pulses from the AC source which creates harmonic distortion. These non-linear current pulses may exceed the nameplate ampere rating of the power source and may cause transformers to run hotter than expected, even when these transformers are supplying less than 50% of their rated nameplate capacity.

With non-linear loads, overloaded neutrals are also showing up in three phase panel boards serving single phase loads. In some cases the neutral conductors carries 180 Hertz currents, rather than 60 Hertz currents. This phenomenon is called triplen harmonics. Triplens are multiples of three, which do not cancel but are additive in the neutral conductor.
