voltage regulator
I am using a voltage regulator, and to get cleaner power, the datasheet recommends using a 0.33uF capacitor. However, it doesn''t say what type it wants. Stupidly, I went out and bought a 10 pack of 0.33uF 50V Radial Electrolytic Capacitors.After looking up on this site, I found that the symbol means that it is a unpolarized capitator. Will they work because they are polarized?

6 FAQs about [Capacitor Reactor Voltage Regulation]
Can capacitive reactive power be used to regulate voltage?
This article presents an efficient voltage regulation method using capacitive reactive power. Simultaneous operation of photovoltaic power systems with the local grids induces voltage instabilities in the distribution lines. These voltage fluctuations cross the allowable limits on several occasions and cause economic losses.
Can a shunt capacitor bank improve a fault current limiting reactor?
The reality is that these voltage drops are in most cases quite small. In cases where such voltage drop is excessive, shunt capacitor banks can be used to improve the power factor of the load and to improve voltage regulation. Determining the appropriate impedance for a fault current limiting reactor is a relatively simple exercise.
What is the maximum reactive power of a shunt capacitor bank?
This discharge may cause a rupture of the failed unit with possible damage to the rest of the bank. To prevent it, the maximum reactive power of one series section should not be higher than 4,650 kvar at a rated voltage and 60 Hz frequency. Refer to IEEE Std. C37.99-1990 “IEEE Guide for Protection of Shunt Capacitor Banks 1.
How is capacitive reactive power produced?
The capacitive reactive power is generated through the capacitance producing devices serially or shunt connected to a load , , . A significant amount of studies was devoted to the methods to produce reactive power, such as DSTATCOMs , , , STATCOM , , , and real electrical capacitors .
Why do generators use capacitors?
Capacitors and reactive loads exchange this reactive power back and forth. This benefits the system because that reactive power (and extra current) does not have to be transmitted from the generators all the way through many transformers and many kilometers of lines. The capacitors can provide the reactive power locally.
Do Series reactors need voltage control?
Series reactors require integration into the electricity network. This requires consideration of aspects such as physical layout, protection coordination, and voltage control. This note describes some aspects of voltage control in applications where series reactors are installed.
