The Loss Angle Tangent Defines the Physical Ratio of Active Power Loss to Reactive Power
The loss angle tangent of a capacitor (usually denoted as tan δ) describes the degree to which the physical current flowing through the capacitor deviates from the ideal 90 degree phase shift under the action of alternating voltage. Due to physical dipole friction and physical leakage resistance within the dielectric, a portion of electrical energy is converted into physical thermal energy. The tangent value of this angle (tan δ) intuitively reflects the physical active power loss generated per unit of reactive power output. For a high-quality Power Capacitor, the physical dielectric loss tangent value is usually extremely small, staying within the physical range of 0.0002 to 0.0005.
Physical Heat Generation Calculation Logic and the Linear Relationship of Power Loss
The physical heat generation of a capacitor is determined by its physical loss power (P). To simplify the understanding, the generation logic of physical heat can be expressed as the product of the following physical parameters:
Physical Power Loss P = Physical Voltage squared × Physical Angular Frequency × Physical Capacitance × Loss Angle Tangent
From this physical logic, we can observe:
- Voltage Sensitivity: Heat generation is proportional to the square of the physical voltage. If the grid experiences a 10% physical overvoltage, the heat generation will increase by approximately 21%.
- Frequency Sensitivity: The physical angular frequency increases with the order of harmonics. In a 5th harmonic (250Hz) environment, even if the loss angle tangent remains constant, the physical heat production is 5 times that of the fundamental frequency.
- Determinant of Loss Angle: The loss angle tangent tan δ is the only physical material variable. If this value doubles from 0.0002 to 0.0004 due to physical aging, the physical heat production of the capacitor will directly double under the same voltage.
The Dynamic Influence Logic of Ambient Temperature and Physical Frequency on the Loss Angle Tangent
The loss angle tangent is not a fixed physical constant; it is highly significantly affected by the physical ambient temperature. When the temperature exceeds 55°C, the physical activity of the dielectric molecules intensifies, leading to a physical increase in tan δ, which in turn triggers even more physical heat generation. This physical positive feedback loop of "rising temperature — increasing loss — higher heat generation" is the primary cause of physical bulging or physical breakdown in capacitors. HertzKron utilizes metallized polypropylene film with stronger physical stability, ensuring that the loss angle remains physically stable within a wide physical temperature range from -25°C to +70°C.
Physical Vacuum Impregnation Process for Long Term Suppression of the Loss Angle Tangent
To reduce the loss angle tangent, HertzKron employs the physical Vacuum Pressure Impregnation (VPI) process during production to completely exclude physical air and moisture from the interior of the physical core. The physical dielectric constant of water is extremely high and its physical loss is massive; even trace amounts of residue can cause tan δ to surge by more than 10 times. Through the extreme drying treatment of physical encapsulation, we control the physical loss rate to below 0.2 watts per kvar. This control of physical precision, combined with a Capacitor Duty Contactor featuring physical current limiting capabilities, ensures the system remains physically cool throughout its 15 year physical service life.
