KUVAG electrical components, German KUVAG models, KUVAG prices

KUVAG electrical components are sensors that convert the state of a measured object into measurable optical signals. The working principle of a fiber optic sensor is to guide the light beam from a light source into a modulator via an optical fiber. Inside the modulator, interaction with external measured parameters causes changes in the optical properties of the light, such as intensity, wavelength, frequency, phase, and polarization state, resulting in a modulated optical signal. This signal is then transmitted via optical fiber to a photodetector and demodulator to obtain the measured parameters. Throughout this process, the light beam is guided through the optical fiber, passes through the modulator, and is then emitted. The primary role of the optical fiber is to transmit the light beam, and its secondary role is to act as an optical modulator.

KUVAG electrical component classification

Generator classifications include: (1) Generators are divided into DC generators and AC generators; (2) AC generators are divided into synchronous generators and asynchronous generators (rarely used); (3) AC generators can also be divided into single-phase generators and three-phase generators. There are many types of generators. Based on principle, they are classified into synchronous generators, asynchronous generators, single-phase generators, and three-phase generators. Based on generation method, they are classified into steam turbine generators, hydroelectric generators, diesel generators, gasoline generators, etc. Based on energy source, they are classified into thermal power generators, hydroelectric generators, etc.

KUVAG electrical component characteristics

Sensitivity refers to the ratio of the change in output to the change in input of a sensor under steady-state operating conditions. It is the slope of the output-input characteristic curve. If there is a linear relationship between the sensor's output and input, then the sensitivity S is a constant. Otherwise, it will vary with changes in the input. The dimension of sensitivity is the ratio of the dimensions of the output and input quantities. When the dimensions of the sensor's output and input quantities are the same, sensitivity can be understood as the amplification factor. Increasing sensitivity yields higher measurement accuracy. However, the higher the sensitivity, the narrower the measurement range, and stability is often poorer.

KUVAG electrical component parameters

1. Voltage temperature coefficient: Refers to the rate of change of the nominal voltage of a varistor within a specified temperature range, i.e., the relative change in voltage across the varistor when the temperature changes while the current through the varistor remains constant. 2. Current temperature coefficient: Refers to the relative change in current flowing through the varistor when the temperature changes while the voltage across the varistor remains constant. 3. Nominal voltage: Refers to the voltage value across the varistor when a DC current flows through it. 4. Voltage ratio: Refers to the ratio of the voltage generated by the current in the varistor to the voltage generated by the current in the varistor. 5. Maximum limiting voltage: Refers to the highest voltage value that can be withstand across the varistor. 6. Leakage current: Also known as standby current, it refers to the current flowing through the varistor at a specified temperature and maximum DC current. 7. Residual voltage ratio: When the current 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. 8. Surge current capacity: Also known as surge current, it refers to the maximum pulse (peak) current value allowed to pass through the varistor under specified conditions (specified time intervals and number of times, applying standard impulse current). 9. Static capacitance: Refers to the inherent capacitance of the varistor itself. 10. Insulation resistance: Refers to the resistance value between the leads (pins) of the varistor and the insulated surface of the resistive body. 22. 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.
