Description
K-Factor Transformers
SolaHD K-Factor transformers are designed to reduce the
heating effects of harmonic currents created by loads.
The K-Factor rating is an index of
the transformer’s ability to withstand harmonic content while
operating within the temperature limits of its insulating system.
SolaHD's K-Factor transformers have UL ratings of K-4, K-13, and
K-20.
The SolaHD K-Factor design is a specialized transformer that
offers these benefits:
Conductors capable of carrying the harmonic currents of non-linear loads without exceeding the temperature rating of the insulation system.
A transformer design that takes into account the increase in naturally occurring “stray” losses caused by non-linear loads. These losses cause standard transformers to dramatically overheat and substantially shorten design life.
A core and coil design that manages the DC flux caused by triplen harmonics. As these harmonics increase, they cause additional current to circulate in the delta winding. This produces a DC flux in the core which leads to core saturation, voltage instability and overheating.
Features
Energy Efficient Compliant to DOE 2016
Conductors to carry harmonics of a K-rated load without exceeding insulation temperature ratings.
UL 1561 Listed up to K-20 rated protection.
Rated temperature rise of 150°C, 220°C insulation.
Shielded for quality power.
Basic design takes “stray losses” into account and functions within safe operating temperatures.
Core and coil design engineered to manage the zero sequence flux caused by triplen harmonics.
Provides 100% rated current without overheating the windings or saturating the core.
Meets transit test requirements for ISTA (International Safe Transit Association) – Test Procedure 1E for packaged-product.
Quiet operation with sound levels 3-6 dB below the NEMA ST-20 requirements
