TRANSFORMER&FURNACE TRANSFORMER&DRY-TYPE
TRANSFORMER&REACTOR Transformer CharacteristicsWinding .The
winding must be especially protected - both against high electrical
stress due to external over voltages and against mechanical
overloads by short circuits. They are made of copper or aluminum.
Low-voltage windings are made of strip or flat wire while high
voltage windings are manufactured from round or profile wire.
("diamond-dotted paper") bonds the winding into a compact block
while drying and increases the short-circuit capacity additionally.
Magnetic Core lamination.The three-limb iron core is made of
oblique cut Grain-oriented, seven-step silicon steel lamination
insulated on both sides, guaranteeing low losses and low noise.
These values are even improved by laser treatment. It is protected
on the surface with a flash-proof varnish in order to prevent the
sheet from corrosion and to reduce the noise. Oil tank.Whether
during transport or operation -the tank must be absolutely tight
under mechanical stress. We have vast constructional experience,
the most modern calculation methods and high-quality welding work.
Special attention is paid to corrosion protection. Pretreatment of
the surface is processed by phosphating pickling, contributes to
corrosion protection, just like multi-coating with preset drying
times for each layer. On request, hot-dip galvanization provides
for even better protection Test labTesting are conducted for every
transformer before delivery.Tests are classified to be routine
tests and type test. A - Routine tests: According to IEC 60076
standard , the following tests must be carried out for all units of
the transformers a- Measurement of winding resistance . b-
Measurement of voltage ratio and check of phase displacement. c-
Measurement of short circuit impedance and load losses.
d-Measurement of no-load losses and current . e-Dielectric routine
tests including the separate source AC voltage withstanding test
and short duration induced over voltage withstanding test ( ACSD )
. B - Type tests : The following tests shall be carried out a-
Temperature rise test b- Lightning impulse test C - Special tests :
a- Determination of noise level according to IEC 60551 . b- Oil
leakage test c- Overload test at 150 % rated current for one hour
after temperature rise test ( top oil temperature rise and winding
temperature rise must be measured and recorded in the report test
also hot spot temperature rise must be calculated and recorded on
the report test ) . d- Short Circuit Dynamic stability Test (test
report from independent and accredited laboratory for similar
transformer will be accepted). Packaging and transportationCompany
