At present, smart capacitors still have a certain market, with favorable prices and easy installation, and are favored by many users.
However, compared to other capacitors, the failure rate of smart capacitors may be relatively high, especially in operating conditions with high harmonic content.
Now the question is, which type of smart capacitor can be used in harmonic situations? Let's take a look at today's article!
Those things about harmonics and capacitors
With the widespread use of nonlinear load equipment under various operating conditions, the generation of harmonics is inevitable. The presence of a large number of harmonics can cause local overheating and additional losses in devices such as capacitors, and in severe cases, may directly render the relevant equipment unusable.
In addition, most capacitors do not have the function of resisting harmonics, and when they encounter harmonics, they amplify them. Compared with ordinary capacitors, smart capacitors have a higher failure rate and are more prone to problems in harmonic environments.
Can smart power capacitors resist harmonics?
At present, there are also harmonic suppression intelligent capacitors on the market, which add filtering reactor modules internally to filter out harmonics and ensure the normal operation of the capacitors.
If there are harmonics in the enterprise power grid and smart capacitors are needed, it is recommended to choose smart capacitors that integrate capacitance and reactance.
However, the editor still wants to tell everyone that if the electrical conditions have severe harmonics, it is not recommended to choose smart capacitors, even if some smart capacitors have harmonic suppression functions.
Each module inside the smart capacitor generates a large amount of heat during operation, and the narrow space cannot guarantee effective heat dissipation. Therefore, smart capacitors are still affected by high temperatures in practical use, leading to frequent malfunctions.
