i want to know the behavior of voltage in 11 KV underground and OH distribution line at different load conditions i.e. no load-full load ...
Voltage behavior in UG cables and OH 11 KV distribution lines

Click For Summary
Discussion Overview
The discussion focuses on the behavior of voltage in 11 KV underground and overhead (OH) distribution lines under varying load conditions, including no load, partial load, and full load. Participants explore the implications of these conditions on voltage and other parameters such as inductance and capacitance, as well as measures to mitigate voltage changes.
Discussion Character
- Exploratory
- Technical explanation
- Debate/contested
- Conceptual clarification
Main Points Raised
- Some participants seek to understand how voltage behaves under different loading conditions in underground and overhead lines.
- Others express that the initial question is vague and request clarification on the specific type of behavior being referred to.
- One participant suggests that regulating voltage requires consulting with a power engineer or studying power system analysis, indicating the complexity of the topic.
- Another participant notes that understanding this subject involves learning basic electrical laws, vocabulary, and physical concepts over time.
- It is mentioned that the capacity between conductors in overhead versus underground cabling can significantly affect performance, particularly over long distances due to phase shift and power factor considerations.
- A participant provides a link to resources regarding the critical length of AC cables, suggesting further reading on the topic.
Areas of Agreement / Disagreement
Participants express varying levels of understanding and approaches to the topic, with some seeking clarification and others emphasizing the complexity of the subject. No consensus is reached on specific behaviors or solutions regarding voltage regulation in these systems.
Contextual Notes
Participants highlight the need for a deeper understanding of electrical engineering principles and the limitations of brief discussions in addressing complex engineering questions.

hi there
welcome to PF
your question is quite vague ... what type of behaviour are you referring to/wanting to know about ?

I meant the change in voltage and other parameters i.e. inductance, capacitance etc in case of different loading like no load , partial loading or full load, and what measures can be taken to prevent any such change .davenn said:hi there

You want to regulate voltage on cables and OH lines. You need to consult with a power engineer, or to study power system analysis enough to do your own engineering.
Answer to questions such as the OP are unlikely to be complete enough to make good choices.

that's not a one afternoon subject.
On the other hand, it's just the laws of Kirchoff and Ohm ...
First one learns the vocabulary
next the basic physical concepts
then the "shorthand" that designers employ to keep the calculations manageable.
As with any field of study It'll take time to become fluent.

One obvious difference between overhead and underground cabling will be the Capacity between the conductors. This can have a very significant effect on very long runs, due to phase shift (/power factor).

I think there are some very informative links here ( Critical length of AC-cables ).
