Energy Efficient Transformers -

Low Voltage Transformer

K-factor rated specifically to withstand harmonic heating and high neutral currents associated with computer equipment and other single phase electronic loads

Schneider Eletric
Energy Efficient Transformers -
  • Features

    Minimum efficiencies have been established for each size of transformer, and extensive design, testing and manufacturing time has been spent to ensure each transformer meets or exceeds these efficiencies.
    The Square D Energy Efficient transformer offering includes all of the popular options including low temperature rise, 115 °C and 80 °C, and aluminum or copper windings.
    These transformers are part of a complete line of Lean Power products from Schneider Electric

    The Environmental Protection Agency (EPA) determined 61 billion kWH of electricity was wasted each year in transformer losses. This finding led the 1992 Energy Act to mandate the Department of Energy (DOE) to evaluate distribution transformers and begin working closely with National Electrical Manufacturing Association (NEMA). NEMA recommended transformer efficiency levels in 1996 – and launched standard TP-1-1996.
    Because the guidelines for reduced energy consumption did not reduce wasted transformer loss – Public Law 109-58, 2005 Energy Act – declared the following regarding low voltage dry-type distribution transformers: "The efficiency of a low voltage dry-type distribution transformer manufactured on or after January 1, 2007, shall be the Class I Efficiency Levels for distribution transformers specified in table 4–2 of the ‘Guide for Determining Energy Efficiency for Distribution Transformers’ Published by the National Electrical Manufacturers Association (NEMA TP–1–2002)."

    Schneider Electric introduced the first TP1-compliant low voltage dry-type distribution transformers in December 1998. With the 2005 Energy Act, Schneider Electric has expanded its offering of TP1-compliant products by launching a new line of TP1 products.

    This new line of products has the following features included in the design:

    Smaller total area used with 3" clearance from ventilated openings instead of 6" Decreased weight

    Sized to handle lug kits coordinating with other Square D® products, increasing ease of installation when used with other Square D equipment  NEMA two-hole terminals allow back-to-back lug mounting for flexibility in feeding multiple panels and extended runs

    200 percent neutral
    Increased wiring compartments provide bending radius for 250 percent primary cables and multiple feeds on secondary cables
