New Department of Energy (DOE) transformer efficiency standard – effective Jan 1 2016

Dry Type Vented

Meets DOE 2016 Transformer Efficiency Standards
A reliable, energy-efficient design for general purpose lighting and electrical applications. Available in single-phase from 15-250kVA and three-phase from 15-1000kVA....
Meets DOE 2016 Transformer Efficiency Standards
K Factor rated for nonlinear loads. These type QL transformers have passed the UL K-factor testing program. GE offers K=4, K=13, K=20 and K=30 transformers.
Meets DOE 2016 Transformer Efficiency Standards
These low noise transformers operate at reduced noise levels. The vibrations within the magnetic steel core have been greatly reduced, thus lowering the humming of the...
Guard I and II Noise Isolation Transformer
Guard I transformers provide common mode noise attenuation and transverse mode noise attenuation. Guard II adds an enhanced level of transverse mode noise attenuation for...
Guard III Harmonic Mitigating Transformer -Meets DOE 2016 Efficiency Standards
Guard III harmonic mitigating transformers help eliminate harmonic currents and minimize power quality problems.
Single-phase 5-25kVA, Three-phase 15-30kVA. Brings together three quality GE products in one convenient, compact solution: transformer, distribution panel and circuit...
Meets DOE 2016 Transformer Efficiency Standards
A Drive Isolation Transformer (DIT) is designed to specifically handle the mechanical stresses, voltage distortions and harmonics associated with SCR applications.

Dry Type Non-Ventilated

Totally Enclosed, Non-Ventilated (TENV) Transformer
15-75kVA, Three-Phase. Totally enclosed non-ventilated transformers are an excellent choice for applications where dry-type transformer benefits are desired but the standard...

Dry Type, Encapsulated, Enclosed

Encapsulated Core & Coil Transformers
The GE QB and QMS transformers feature encapsulated core and coils in a NEMA 3R nonventilated weatherproof enclosure.
QMS3 Transformer
This GE QMS3 transformer features encapsulated core and coils in a NEMA 3R nonventilated weatherproof enclosure. It is available in 3-15kVA.
Buck Boost Transformer
Convenient and least expensive method of matching line voltage with equipment voltage. Primary voltages: 120V, 240V and 480V. Secondary voltages: 12V, 16V, 24V, 32V, 48V.

Control Power Core & Coil

Terminal Board Connection Transformers
Used to provide voltage to control devices in applications where regulation and minimum space are important.
Transformer - Leads Out Connections
The lamination core is welded to provide superior, quiet performance. These designs are rated at 55 ° C rise with 40° C ambient.
