electricpy.suspension_insulators(number_capacitors, capacitance_ratio, Voltage)[source]¶

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
