Welcome to PF.
I guess the subject is; The quality of AC power. Flicker emission limits for energy users on a power distribution network.
Pst; short term parameter.
Plt; long term parameter.
Power-line flicker is a visible change in brightness of a lamp due to rapid fluctuations in the voltage of the power supply. The voltage drop is generated over the source impedance of the grid by the changing load current of an equipment or facility. These fluctuations in time generate flicker.

Flicker is a multi-cycle effect. I see nowhere to store several cycles of energy in the step-up transformer. I therefore assume that flicker will not be significantly attenuated by the LV to HV transformation at the generation site.

To reduce flicker from static inverters would require something equivalent to a synchronous motor/generator, with a heavy flywheel.
 

1. What does "Decrease in Psti and Plti values with transposed Pst and Plt (@LV) to HV" mean?

This phrase refers to a decrease in the values of Psti and Plti, two scientific measurements, when they are transposed from a low voltage (LV) to a high voltage (HV) setting.

2. Why would Psti and Plti values decrease when transposed from LV to HV?

This decrease in values is likely due to the change in voltage levels. Different voltage levels can affect the behavior and properties of scientific measurements, resulting in a change in their values.

3. Are Psti and Plti values important in scientific research?

Yes, Psti and Plti values are important in scientific research as they are commonly used to measure and analyze the electrical properties of materials. They can provide valuable information about the conductivity, resistivity, and other characteristics of a substance.

4. Can Psti and Plti values be affected by other factors besides voltage?

Yes, Psti and Plti values can also be influenced by other factors such as temperature, pressure, and the composition of the material being measured. It is important to consider and control for these factors when conducting experiments.

5. How can a decrease in Psti and Plti values impact scientific research?

A decrease in Psti and Plti values can affect the accuracy and reliability of scientific research, as it may alter the interpretation of results and conclusions drawn from the data. It is important to understand and account for any changes in these values to ensure the validity of experiments and studies.
