The voltage distribution across insulator strings is not equal, this because exist capacitances beteween insulators and tower and between insulators and conductor. So how i can calculate the stray capacitances across insulator strings?

Creepage distance in insulators?
It is the shortest distance between the conductors measured along with the surface of insulators.
What is the difference between capacitive reactance and capacitance?
Capacitance is a physical characteristic of a pair of conductors, dependent upon the distance between them, the opposing cross-sectional areas of those conductors, and the nature of the dielectric between them, and is measured in farads.Capacitive reactance is the opposition to the flow of current of a circuit, determined by that circuit's capacitance and the frequency of the a.c. supply applied to that circuit, and is measured in ohms.
How capacitance effects are taken into account in transmission lines?
Natural capacitance exists between conductors at different potentials, including between those conductors and earth (ground). The value of such capacitance is significantly higher with underground cables than with overhead lines, due to the close proximity of the individual conductors in an underground cable. Capacitance results in line losses in both a.c. overhead and underground systems, due to the corresponding capacitive reactance (opposition to a.c.). In the case of long, high-voltage, underground or under-sea cables, the capacitance losses can be so high that d.c. transmission is used instead of a.c. (d.c. eliminates capacitive line losses). In addition to the line losses, the electric fields resulting from the capacitance can lead to insulation breakdown -making it essential that 'sharp corners', etc., are avoided in their design and construction. One of the reasons that high-voltage overhead conductors are 'bundled' (i.e. more than one conductor per line) is to reduce the stress on individual line conductors that would otherwise occur due to their relatively small diameters.
Explain the difference between conductors semiconductors and insulators?
Metals are good conductors of electricity. Insulators are bad conductors of electricity. Similarly, semiconductor devices are partial conductors of electricity means their conductivity lies between conductors and insulators.
Why semiconductor is called semiconductor not semiinsulator?
The purpose of semiconductors is to control the amount of conduction, not the amount of insulation.
Does capacitance exists between two current carrying conductors?
Capacitance exists between any two conductors, current carrying or not.
Differences between conductors and insulators?
Conductors let energy (such as electricity and heat) flow through them easily while insulators do not.
What is the difference between capacitance and stray capacitance?
Capacitance is an ability to store an electric charge. "If we consider two same conductors as capacitor,the capacitance will be small even the conductors are close together for long time." this effect is called Stray Capacitance.
Are scissors conductors?
They are Conductors, not much for insulation though. Differences between conductors and insulators? Conductors let energy such as electricity .
Creepage distance in insulators?
It is the shortest distance between the conductors measured along with the surface of insulators.
Substance in between conductors and insulators used in transistors?
Semiconductors
Difference between stray and parasitic capacitance?
Parasitic capacitance is unavoidable and usually unwanted capacity between two or more conductors which exists due to close proximity and which typically causes non-ideal circuit behavior. Stray capacitance, as it is typically thought of, is a type of parasitic capacitance. It is the capacity from a conductor to its surroundings which is the aggregate of the conductors in its environment inversely weighted by the distance to each of the environmental conductors.
How do you know the difference between conductors and insulators?
Yes I do, a thermal insulator keeps in the heat
What is the similarities between conductors and insulators?
Conductors and insulators are different and simalar in many ways.Two ways they are simallar are they both have electrons and have something to do with electricity.Three ways they are different that conductors let heat and electricity go through it .On the other hand insulators do not let heat or electreicity go through it easily.Another way is conductors transfer eelectrons easily but meanwhile the insulator psses on electrons with difficulty.One last thing is that conductors are not current but insulators are current.

Why do you use semiconductor why not conductors and insulators by changing their properties?
We use semiconductors instead of conductors and insulators by changing their properties because the properties of a semiconductor lies between that of a good insulator ant that of a good conductor. Any of the materials obtained depends on the level of doping.
The property of an electrical device that permits storage of electrically separated charges when potential differences exist between the conductors is called what?
Capacitance.
