Transformer with On-Load Tap Changer (Regel)

It is developed to regulate the changes in voltage automatically and prevent the negative effects occured
because of these changes. Number od steps at Transformer with On-Load Tap Changer are designed as 9,
10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29,30,31,32,33,34,35 considering the needs of end
System can be controlled automatically via microprocessor-based automatic voltage requlator (AVR)
without the need for intervention of an operator and voltage output precision can be adjusted under energy
from remote by operator; tap changing can easily be made manually when needed and enables remote
control and monitoring.
During tap changing operation, a constant stable voltage without voltage fluctuations is offered to users.
Tap changer units have electrical and mechanical structure which do not require maintenance for years
and these units have successfully passed the tests performed at international laboratories that proves their
Transformers with On-Load Tap Changer transformers are manufactured with expansion tanks and used
as internal type.


Furnace transformers, railway transformers,Solar and Wind Power transformers and transformers with
different voltage levels are designed by R&D department and presented to customers according to various
All transformers are manufactured according to TS 267, EN60076,BS, CEI/IEC and other demandable
product standarts having TS EN ISO 9001:2000 Quality Management System and OHSAS 18001 Health of
Workers and Security Management System certificates.
Transformers manufactured in accordance with dynamic effects of short circuit tests and approved by
KEMA Holland and ICMET Romania.


Low voltage and high voltage windings in Distribution and Power transformers are constituted by using
round and profile electrolytic copper and aluminum, Class A isolation paper and transformer board
materials with convenient winding techniques according to current and voltage situations.
Low and high voltage windings are resistable to atmospheric shock wave in cylinder or oval winding type.
Mechanical pressing is appiled against short circuit dynamic forces. Adequate axial and radial channels
are left for cooling of windings.
