Elektra Elektronik's transformers are in a leading position in Turkey's low- and medium-voltage transformer and reactor industry in terms of production capacity and export share. Its transformers are being used in a wide range of industries that use automatic transformers for control, isolation, medical, automotive and motor starters. 50% of the company's transformers are exported to 60 countries around the world. Now, Elektra Elektronik is preparing to double its production capacity to strengthen its market penetration to meet the growing international demand and market share. In addition, Elektra Elektronik's goal is to establish a research and development center to further simplify research and development activities.
Elektra's transformers are commonly used for energy transmission and distribution, and there are five different product lines, such as control, isolation, medical, automotive and motor starter automotive transformers. With high magnetic permeability iron core, optional copper or aluminum winding, low loss, high efficiency, silent operation, vacuum painting to prevent moisture and other characteristics, these transformers comply with European standards and carry the CE mark (ISO 9001 quality standard ) Management system).
Control transformers are widely used in distribution boards, with input and output voltages up to 1000 V, and special winding options such as voltage taps or shielded windings. According to customer needs, the rated power of these transformers can reach 10kVA. The electrical connection is done through terminal blocks. Special installation of DIN rail is available on request. The control transformer ensures the high current required by the relay without significantly reducing the output voltage. Called "short-time power", this value must be defined for any control transformer.
Isolation transformers are designed for use in three-phase systems that require galvanic isolation and step-up or step-down. Input and output voltages can reach up to 5000V, and voltage taps or shielded windings are also provided. Upon request, a nacelle shell can be provided, and the rated power of the transformer can be changed to 1600kVA as required. The electrical connection is done through terminal blocks or flat cables. Any vector connection type can be provided upon request.
Transformers used in hospitals and clinics must be designed specifically for these applications because they power very sensitive loads. Elektra Elektronik's medical transformers have excellent resistance to high-voltage pulse strength, the level of isolation strength between the conductor and the protective earth, or sensitivity in preventing potential leakage of the winding. It complies with EN-61558-2-15 and is produced in accordance with European standards under the ISO 9001 quality management system. Medical transformers include very low levels of inrush current (<12*In) and idle current (<3%), and good voltage regulation (<3%), the residual current is close to zero, the mid-end dedicated built-in PTC, thermal measurement isolation level.
Autotransformers are mainly used in motor starting, voltage regulation and energy efficiency circuits, and are used to regulate voltage levels without galvanic isolation. Unlike isolation transformers, their size changes according to the voltage value. The input and output voltage can reach up to 3000V. Upon request, additional voltage taps or shielded windings can be provided. The rated power of these transformers can reach 1600 kVA. For electrical connections, use bus bars or terminal blocks. Any connection type can be provided to meet any customer needs. These transformers comply with all sub-standards of EN 61558-2-13.
The motor starting transformer is used to limit the inrush current when the motor starts. Compared with the nominal voltage, the rated value of the main output voltage tap is 70%. Therefore, half of the rated torque cannot be applied to the motor shaft. In this case, the starting current of the motor is lower than the rated current, and the protection device will not be triggered. After the motor starts and reaches the rated operation, the output voltage point is transferred to the input voltage point, and the motor is switched to the rated operation mode. Therefore, in order to cool down to the next start-up time, the transformer is deactivated. Due to this method of operation, a much smaller transformer can be designed than conventional transformers.
