All other deviations in the Y capacitances cause the leakage current to change in the same direction, that is, the capacitance increases and the leakage current also increases. Equation (8) can also be used to find the contribution of the deviation of each capacitor to the leakage current.
The Equation (8) clearly shows the amount of change in leakage current caused by each Y capacitor error. It is noted that only the deviation in capacitance of the Y capacitor C3 can cause the leakage current to change in the opposite direction, that is, as the C3 capacitance increases, the leakage current decreases.
C = 4 π ϵ 0 (1 R 1 − 1 R 2) − 1. It is interesting to note that you can get capacitance of a single spherical conductor from this formula by taking the radius of the outer shell to infinity, R2 → ∞. R 2 → ∞. Since we will have only one sphere, let us denote its radius by R. R. C single sphere = 4πϵ0R. C single sphere = 4 π ϵ 0 R.
