Turkey electronics industry pioneer of Elektra Electronics provides high cost savings with its world-class auto transformers
Having a long history of 40 years in the field of transformer (transformer) production and energy quality, Elektra Elektronik provides significant size and cost savings with auto transformers, which are mainly used in the mining and ship sector. Auto transformers, which offer a more affordable solution than an isolation transformer of the same power, are generally applied in motor starts, voltage regulation and energy efficiency circuits.
In terms of production capacity and exports reactors with low and medium voltage transformer sector in Turkey leading position in the company, Elektra Electronics, auto transformers produced with a high proportion of size and provides cost savings opportunities. Auto transformers, which are mainly used in the mining and shipbuilding industry, are generally used in motor starts, voltage regulation and energy efficiency circuits to change the voltage level without providing galvanic isolation.
Size savings of up to 50 percent with auto transformers
In applications where galvanic isolation is not required and the voltage level needs to be changed, auto transformers are preferred instead of isolation transformers. With auto transformers, size savings of up to 50 percent can be achieved depending on the voltage values used in the application. It is often used to adjust the voltage level, especially when starting asynchronous motors. In cases where delta-star switching is not possible, using an auto-transformer with a suitable voltage output, the excessive current drawn by the motors during start-up can be highly restricted. In addition, it is possible to achieve the desired torque value at the time of take-off with the appropriate auto transformer design.
Production in custom sizes, power values and connection types
Elektra Elektronik's auto transformers can be produced in sizes, power values and connection types on demand. In auto transformers, which offer a more affordable solution compared to an isolation transformer of the same power, the dimensions change according to the voltage values, unlike the isolation transformers. Input and output voltages can vary up to 3000V. Depending on customer demand, production can be made with extra output terminals and screen coils. Power levels of these transformers can reach up to 1600 kVA. Electrical connections are provided by busbars or terminal blocks.
Complies with all required standards ...
Elektra Elektronik auto transformers, which can be produced with any connection type needed, stand out with their compliance with all sub-standards of EN 61558-2-13. Elektra Elektronik auto transformers, which have features such as high magnetic permeability iron core, optional copper or aluminum winding, low loss, high efficiency, silent operation and varnishing in vacuum for moisture protection, are produced under ISO 9001 Quality Management System in accordance with CE mark and European standards. .
Frequently used in voltage regulators as well as in the mining and ship industry
Auto transformers are also frequently used in voltage regulators. When galvanic isolation is not mandatory in regulators, a serious size and cost saving can be achieved with the use of auto transformers. In shipping, another sector where size savings gain importance, since all kinds of space on the ship are limited, auto transformers are used instead of isolation transformers at points where voltage levels need to be adjusted. In addition, it is frequently preferred in the mining sector.
Since the current values obtained in the applications of auto transformers are different from the winding current values, the manufacturer is consulted for the selection of the appropriate auto transformer. The heating calculations differ from the isolation transformers due to the conversion rate and the intermittent operating time. Two autotransformers feeding the same power can have very different dimensions due to variations in voltage levels.
Elektra Elektronik designs and manufactures its products in accordance with international standards, offering high added value to its customers with high quality auto transformers in accordance with IEC 61558-2-13 for small type transformers and IEC 60076 for large type transformers.
