elektra electrical components, German elektra models, elektra prices

elektra electrical components is a general term for all single components based on semiconductor materials, including diodes, transistors, field-effect transistors, and thyristors (the latter three are all three-terminal devices) made from various semiconductor materials. A transistor is a semiconductor device commonly used in amplifiers or electronically controlled switches. Transistors are the basic building blocks for the standard operation of computers, mobile phones, and all other modern electronic circuits. Due to their fast response speed and high accuracy, transistors can be used for a wide variety of digital and analog functions, including amplification, switching, voltage regulation, signal modulation, and oscillation. Transistors can be packaged individually or as part of an integrated circuit in a very small area that can accommodate one hundred million or more transistors.

elektra electrical component parameters

1. Nominal varistor voltage: refers to the voltage value across the varistor when a pulse current of specified duration passes through it. 2. Voltage ratio: refers to the ratio of the voltage value generated by the current in the varistor to the voltage value generated by the current in the varistor. 3. Maximum limiting voltage: the peak voltage across the varistor under the maximum pulse peak current Ip that the varistor can withstand and under a specified waveform. 4. Residual voltage ratio: when the current passing through the varistor is at a certain value, the voltage generated across it is called the residual voltage for that current value. The residual voltage ratio is the ratio of the residual voltage to the nominal voltage. 5. Current handling capacity: also known as surge current capacity, it refers to the maximum pulse current value allowed to pass through the varistor under specified conditions. 6. Leakage current: also known as standby current, it refers to the current flowing through the varistor when the varistor is at a specified temperature and under maximum DC voltage. 7. Voltage temperature coefficient: refers to the rate of change of the nominal voltage of the varistor within a specified temperature range, i.e., the relative change in voltage across the varistor when the temperature changes while the current passing through the varistor remains constant. 8. Current temperature coefficient: refers to the relative change in the current flowing through the varistor when the temperature changes while the voltage across the varistor remains constant. 9. Voltage nonlinearity coefficient: refers to the ratio of the static resistance value to the dynamic resistance value of the varistor under a given applied voltage. 10. Insulation resistance: refers to the resistance value between the lead wires of the varistor and the insulated surface of the resistive body. 11. Static capacitance: refers to the inherent capacitive capacity of the varistor itself. 12. Rated power: the maximum power that causes a change in varistor voltage when operating at a specific ambient temperature. 16. Maximum impulse current: the maximum impulse current that causes a change in varistor voltage when the varistor is subjected to a specific pulse current impulse once or twice.

elektra electrical component characteristics

(1) Wide transient response range and strong harmonic measurement capability. The quality of transient characteristics is an important parameter for judging whether a transformer can be applied in a power system, especially in coordination with the operating time of relay protection. Traditional electromagnetic transformers have poor response characteristics to high-frequency signals due to the presence of an iron core and cannot correctly reflect the transient process on the primary side. In contrast, the frequency range of optical-electronic transformers is mainly determined by the electronic circuit section, without the problem of iron core saturation, so they can accurately reflect the transient process on the primary side. The structure of optical sensors allows for the measurement of harmonics on high-voltage power lines, which is difficult to achieve with electromagnetic induction transformers. (2) Digital interface with strong communication capability. Since the optical sensor outputs optical digital signals, it interfaces easily with communication networks, and there is no measurement error during transmission. Meanwhile, with the widespread adoption of microcomputer-based protection and control equipment, optical-electronic transformers can directly provide digital quantities to secondary equipment, thereby eliminating the transformers and A/D sampling sections in the original protection devices, greatly simplifying secondary equipment and promoting research into new protection principles. (3) Small size, light weight, and easy upgradability meet the requirements for miniaturization and compactness of substations. Since optical sensors rely on sensor heads and electronic circuits for signal acquisition and processing, they are small in size, with a weight generally below 1000 kg, making them easy to integrate into AIS or GIS, thus greatly reducing the floor space of substations and meeting the requirements for substation miniaturization and compactness. At the same time, connecting optical-electronic transformers to secondary equipment via a small number of optical fibers can significantly reduce cable trenches and cables.

elektra electrical component classification

Self-inductance occurs when a current passes through a coil, generating a magnetic field around it. When the current in the coil changes, the surrounding magnetic field changes accordingly, and this changing magnetic field induces an electromotive force (induced EMF) in the coil itself. This is self-inductance. An electronic component made by winding wire with a certain number of turns, capable of producing a certain amount of self-inductance or mutual inductance, is often called an inductor coil. To increase inductance, improve the quality factor, and reduce volume, an iron core or magnetic core made of ferromagnetic material is often added. The basic parameters of an inductor include inductance, quality factor, inherent capacitance, stability, current rating, and operating frequency. An inductor composed of a single coil is called a self-inductor, and its self-inductance is also known as the self-inductance coefficient. Mutual inductance occurs when two inductor coils are close to each other; a change in the magnetic field of one coil affects the other. This effect is mutual inductance. The magnitude of mutual inductance depends on the self-inductance of the coils and the degree of coupling between them. Components manufactured using this principle are called mutual inductors.
