Olsun Electrics HM harmonic mitigating style transformers are designed for
non-linear loading applications such as those utilizing switch-mode
power supplies. This type of loading includes computers and
computer servers and related equipment such as printers, monitors
and copiers… most any electrical equipment utilizing a resident
power supply. Related applications include data centers, schools
and office buildings, theater and recording studios, financial and
similar institutions where single phase line-to-neutral equipment
containing switching power supplies are used.
Utilizing flux cancellation and phase shifting designs, Olsun HM
transformers mitigate third order (triplen) harmonics seen by the transformer, preventing primary winding coupling and the resulting noise that
would be reflected back onto the feeding circuit.
Silica Resin Encapsulated Transformers
The Silica Resin Encapsulated transformer is the result of many
years of continuous refinement by Olsun Electrics. Two Olsun
product types, recognized in the market as the SilPac and HazPac, were developed and expanded as a result of a growing need for a
compact and economical dry type transformer that was virtually
impervious to harsh environmental conditions, such as those
encountered in chemical plants, refineries, dairies, marinas,
shipboard use, etc. Product durability, quiet operation, and
flexibility in designing the encapsulated transformer for your
application make Olsun the clear choice.
Hazardous Location Applications
Olsun Electrics HazPac transformer line is designed and built
specifically for hazardous locations in compliance with article 500
of the NEC and is UL* listed for Class 1, Division 2, Groups A, B,
C & D locations. And with a North American Temperature
Classification of T3C, HazPac keeps its cool under load—when you
and the surroundings need it to be. Couple our dedicated hazardous
duty design with high short-circuit strength, 80°C rise
availability and Olsun’s industry proven reliability and you’re
literally playing it safe in choosing Olsun for long life in your
Who invented the transformer? Ottó Bláthy, Miksa Déri, Károly
Zipernowsky of the Austro-Hungarian Empire First designed and used
the transformer in both experimental, and commercial systems. Later
on Lucien Gaulard, Sebstian Ferranti, and William Stanley perfected the design. See the next question for more details.
When was the transformer invented? The property of induction was
discovered in the 1830's but it wasn't until 1886 that William Stanley, working for Westinghouse built the first reliable commercial
transformer. His work was built upon some rudimentary designs by
the Ganz Company in Hungary (ZBD Transformer 1878), and Lucien
Gaulard and John Dixon Gibbs in England. Nikola Tesla did not
invent the transformer as some dubious sources have claimed. The
Europeans mentioned above did the first work in the field. George
Westinghouse, Albert Schmid, Oliver Shallenberger and Stanley made
the transformer cheap to produce, and easy to adjust for final use.
Where were the first transformers used? The first AC power system
that used the modern transformer was in Great Barrington,
Massachusetts in 1886. Earlier forms of the transformer were used
in Austro-Hungary 1878-1880s and 1882 onward in England. Lucien
Gaulard (Frenchman) used his AC system for the revolutionary Lanzo
to Turin electrical exposition in 1884 (Northern Italy). In 1891
mastermind Mikhail Dobrovsky designed and demonstrated his 3 phase
transformers in the Electro-Technical Exposition at Frankfurt, Germany.
Varieties of Transformers
There are many types of transformers with different designs used
for all kinds of applications from radio to microelectronics.
Simply can be divided into oil immersed transformer and dry type
Main components of transformers
The most important components of transformers are core and coil.
They are the heart of a transformer. Besides that, oil tanks,
casing and some controlling devices are also essential parts of a
