Power Transformers
8
Most of the transformers supplied to the market by ABB
use Core Type Technology. They are mostly used in
customer applications as generator step up and system
intertie power transformers.
Large Power Transformers are defined within ABB as units
with a three phase power rating higher than 200 MVA or
with voltage ratings higher than 275 kV. ABB supplies
three phase units up to 1100 MVA and single phase units
up to 500 MVA. Power transformers for system voltages
up to and including 800 kV have been delivered to the
market since the 1970’s.
HVDC Converter Transformers
10
The HVDC converter transformer is a key component in
an HVDC transmission system. In addition to its normal
application to provide transfer of power between two
voltage levels, it serves a number of additional functions
like galvanic separation between the AC and DC systems.
A fairly large tapping range permits optimum operation
also for a large variation in load without loss of efficiency.
Polytransformer
12
ABB has developed a new product in the transformer
world, The Polytransformer. This transformer is designed
with multiple voltage ratings on the HV, the LV and
tertiary side that allow it to work in substations and power
plants at different voltages.
Impedances and MVA ratings are chosen to cover most of
the applications.
Single phase and three phases units are available.
Its compactness and flexibility of use make the
Polytransformer the ideal universal transformer for any
transmission and generation system.

The worldwide concept for core type
power transformers
Shunt Reactors
9
Shunt reactors are a vital part of the efficient operation of
long transmission or AC cable high voltage power lines.
The shunt reactor compensates the capacitive generation
on power lines to avoid non-controlled voltage rise
especially on lightly loaded lines. The proven design and
robust build-up makes the shunt reactor the most cost
efficient mean to absorb the capacitive generation.
Phase-Shifting Transformers
11
Phase-shifting transformers help control the real power
flow in transmission lines and systems interties. Existing
transmission systems are often operated and stressed to the
limit of the performance capability of their original design
in order to maximize asset utilization. To ensure that
under these conditions the economical, reliable and secure
operation of the grid is maintained, the need for various
aspects of power flow management within the power
systems is becoming evident. Phase-shifting transformers
help control the real power flow in transmission lines
and systems interties. They allow for better utilization of
existing networks concerning load growths.
Shell Type Transformers
13
With Shell Type, ABB uses a completely proven
technology concept for manufacturing power transformers
covering voltages up to 525 kV.
Shell technology is implemented in ABB Power Technology.
It means simple, robust and reliable construction.
All processes and quality are supervised by a 6-Sigma
system. Shell Type transformers have the natural ability
to withstand short-Circuit and transport stresses, and
exceptional compactness. Design flexibility allows us to
match existing units both mechanically and electrically and
supply universal transformer spares with multi-rated high
and low voltage ratio for different power stations.
