What types of capacitors do power companies use to feed the grid?

Lower losses and lower harmonics Ceramic Capacitors are very beneficial in power grids. By producing reactive power, they compensate for the reactive power consumption of electri-cal motors, transformers, etc. The results can be seen in the form of more stable power grids with increased transmission capacity, reduced losses thanks to higher power factors.(Harmonic filtration: As electrical consumption increases, demands on availability and high electrical quality are also increasing.It is important that the harmo-nic content is limited in the supply voltage. Developments during recent years, however, point to a strong increase in the amount of har-monics in power grids.

In industrial grids, har-monics are generated by non-linear loads such as rectifiers, static frequency converters, arc furna-ces, etc.Even in distribution networks, harmonics are produced by, for example, computers and low-energy lamps. Harmonics can lead to several problems, such as: increased losses in machines and apparatuses, control system faults or distur-bances in electronics and computers. Fortunately, the problems can be prevented using suitably adapted harmonic filters consist-ing of capacitors, reactors, and in some cases, even resistors) QBANK open-rack banks for voltages up to 500 kV QBANK is a flexible concept for open-rack shunt banks and enables very compact solutions that save space at installations.

Configuration and power can be varied within wide ranges. QBANK is supplied with internally fused, externally fused or fuseless configurations depen-ding on the bank’s voltage and power level DryQ represents the latest technology in the field of capacitors, making it possible to build shunt banks in an even more cost-effective and environmentally friendly manner. DryQ is a liquid-free capacitor with an entire-ly new enclosure technology.It consists of seri-al-connected capacitor blocks that are stacked on one another in a tube-shaped, silicone-filled casing.

The absence of liquid entirely elimina-tes leakage risks. The outer casing consists of silicone rubber with optimal properties when it comes to climatic and environmental stresses.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
