Discrete Capacitors Voltage in a Suspension Insulator Strain.

To perform the calculations described here, the following formulas are satisfied, and used to construct a matrix used to solve for \(V_i \text{i in range(1,n)}\).

\[\sum_{i=1}^{n-2} V_{i} + V_{n-1} \cdot (1+m) - V_{n} \cdot m=0\]
\[\sum_{i=1}^{n} V_{i} = V_{\text{transmission line}}\]

Additional Information

Parameters:
number_capacitors : int

Number of disk capacitors hung to transmission line

capacitance_ratio : float

Ratio of disk capacitance and pin to pole air capacitance

Voltage : float

Voltage difference between the transmission line and ground

Returns:

  • string_efficiency (float) – String efficiency of capacitive disks

  • capacitor_disk_voltages (float) – Voltage across each capacitive disk starting from top to bottom
