Equivalent Circuit of 5 Disc Suspension Insulator
- The equivalent circuit of a 5-disc suspension insulator consists of 5 discs connected in series.
- Each disc has capacitance and leakage resistance associated with it.
Voltage Across Each Disc in a String
- Let V be the total voltage applied across the 5-disc string.
- The voltage across each disc in the string can be calculated using the voltage divider rule.
- Let V1, V2, V3, V4, and V5 be the voltages across each disc respectively.
- The total capacitance of the string is the sum of capacitances of each disc, denoted as C_total.
- The voltage across each disc can be calculated as:
V1 = V * (C1 / C_total)
V2 = V * (C2 / C_total)
V3 = V * (C3 / C_total)
V4 = V * (C4 / C_total)
V5 = V * (C5 / C_total)
String Efficiency
- String efficiency is a measure of how effectively the insulator string distributes the total voltage across all the discs.
- It is defined as the ratio of the voltage across the whole string to the sum of the voltages across each disc.
- Mathematically, string efficiency (SE) can be expressed as:
SE = V_total / (V1 + V2 + V3 + V4 + V5)
- A higher string efficiency indicates better voltage distribution across the discs in the string.
- String efficiency is an important parameter to consider in the design and operation of insulator strings in power systems.
