stray capacitance calculation
Yes, all electronic components have both stray capacitance and stray inductance.
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?
In the Hay bridge, the capacitor is placed in series to improve the sensitivity of the measurement, allowing for a more accurate determination of capacitance by minimizing errors from stray capacitance. Conversely, in the Maxwell inductance-capacitance bridge, the capacitor is used in parallel to facilitate the comparison of inductance and capacitance directly, enabling a more straightforward calculation of circuit parameters. The differing configurations serve the specific needs of the measurement techniques employed in each bridge design.
A bridge has an upper frequency limit because above that frequency the measuement accuracy fails because of stray capacitance and inductance inside the bridge device.
To calculate the capacitance of a 3X120 sq.mm PILC (Paper Insulated Lead Covered) cable, you can use the formula for the capacitance per unit length of a three-core cable, which is approximately ( C = \frac{2\pi \epsilon}{\ln(\frac{D}{r})} ), where ( \epsilon ) is the permittivity of the insulation material, ( D ) is the distance between the conductors, and ( r ) is the radius of the conductor. The total capacitance can then be derived by multiplying the capacitance per unit length by the length of the cable. Specific values for ( \epsilon ), ( D ), and ( r ) should be obtained based on the cable's construction and insulation type.

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.
Stray capacitance is undesired capacitance. Any electronic component (wires, resistors, etc.) has SOME capacitance; at high frequencies, this can become significant, becoming a problem for circuit design.
depends on circuit and its construction.
due to the load gates capacitance values,there is a increased load capacitance on the driving gate
You can reduce stray capacitance by avoiding having long wires running parallel in circuits. Keep wires as short as possible. Long wires running along each other can exhibit stray capacitance effects. Another way is to cut long leads of components such as capacitors and inductors to make them as short as possible. If best, use SM components, as they have no leads which can cause this stray capacitance effect.

ANSWER Stray capacitance is the capacitance in a circuit not caused by capacitor components. There is a small capacitive effect, often on the order of a few picofarads, between leads of ICs, traces on a PCB, wires in a cable, the power and ground planes in a PCB, etc. In high-speed circuits, stray capacitance can be enough to completely change the operation of a circuit -- even to the point of keeping it from working as designed. Note that capacitor "components" can include PCB traces specifically designed to act as capacitors.
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.
stray capacitance(one that develops between wires ,conductors within the circuit) is obviously not useful as it alters the effective values of circuit components when developed in the oscillators and hence it destabilize the frequency of oscillations Engr.syed mudassir hussain
Any two objects that occupy the same universe have capacitance between them. In electronic circuits components are quite close to each other, and this capacitance is often a nuisance, causing cross-talk, instability, and signal losses.
