Transformers

Transformers are devices used to trade voltage for current in a circuit in electric power applications for uninterrupted operation. Transformers are essential for the transmission, distribution, and utilization of alternating current electric power. GE and ABB have a range of different types of transformers to fit your electric power needs.

Dry Type Vented

General Purpose

Reliable, energy-efficient design for general purpose lighting and electrical applications. Available in single-phase from 15-250kVA and three-phase.

K-Factor

ABB’s type QL K-Factor transformers are designed to withstand the additional heating that accompanies the presence of harmonics in electrical systems.

Low Noise

Our 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 & II Noise Isolation Transformer

Guard I Noise Isolation Transformer

Guard I noise isolation transformers provide common mode noise attenuation and transverse mode noise attenuation.

Guard II Electrostatic Shielded Transformers

Guard II transformers incorporate the same electrostatic shield as the Guard I plus additional noise and surge suppression components

Guard III Harmonic Mitigating

Guard III Harmonic Mitigating Transformers help eliminate harmonics, improve power quality, and help save energy by reducing the energy (heating) losses. They maintain...

Single Phase Servicenter Integral Transformer and Distribution Panel

Servicecenter -Single-phase 5-25kVA, Three-phase 15-30kVA. Brings together three quality products in one convenient, compact solution: transformer, distribution panel and...

Three Phase Servicenter Integral Transformer and Distribution Panel

Three Phase Servicenter: Integral Transformer and Distribution Panel

Drive Isolation Transformer

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 transformers

Totally Enclosed, Non-Ventilated (TENV)

TENV transformers are recommended where dust, dirt, or lint may be present or where transformers are subject to sprays or controlled wash-down conditions.

Medium Voltage Instrument Transformers & Sensors
ABB manufactures medium voltage instrument transformers according to ANSI, IEC, GOST, GB, BS, and DIN standards.

medium voltage Instrument transformers and sensors

ANSI instrument transformers for indoor applications

ANSI instrument transformers for indoor applications are available in voltage classes ranging from 0.6 kV to 35 kV.

Medium voltage sensors for indoor applications

Medium-voltage indoor sensors

The ABB solution for measuring currents and voltages for protection and monitoring in medium voltage power systems.

Dry Type, Encapsulated, Enclosed

Single-Phase: .050kVA-3kVA and 5kVA-15kVA

QB and QMS transformers feature encapsulated core and coils in a NEMA 3R nonventilated weatherproof enclosure.

Buck-Boost

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

Used to provide voltage to control devices in applications where regulation and minimum space are important.

Leads Out Connection

The lamination core is welded to provide superior, quiet performance. These designs are rated at 55 ° C rise with 40° C ambient.

Secondary Substation

Ventilated Dry-Type

Designed for indoor or outdoor applications in schools, hospitals, industrial plants, commercial buildings and anywhere that safe and dependable power are important...
