1. What is a pole-mounted substation?
   A pole-mounted substation is an electrical substation installed on utility poles, typically used in rural or semi-urban areas to step down high-voltage electricity for local distribution.

2. How does a pole-mounted transformer work?
   A pole-mounted transformer steps down high-voltage power from distribution lines to lower voltages suitable for residential or commercial use, usually converting 11kV/33kV to 400V/230V.

3. What are the advantages of pole-mounted transformers?
   They are cost-effective, easy to install, require less space, and are ideal for areas where ground space is limited or expensive.

4. What is the typical capacity of a pole-mounted transformer?
   Pole-mounted transformers usually range from 16 kVA to 100 kVA, depending on the power demand of the area they serve.

5. How are pole-mounted substations maintained?
   Regular maintenance includes visual inspections, oil level checks, insulation testing, and cleaning to ensure efficient operation and prevent failures.

6. What safety features do pole-mounted transformers have?
   They include lightning arresters, fuses, and protective relays to prevent damage from surges, overloads, or short circuits.

7. Can pole-mounted transformers be used in urban areas?
   Yes, but they are more common in rural or semi-urban locations due to space constraints and aesthetic considerations in cities.

8. What is the lifespan of a pole-mounted transformer?
   With proper maintenance, they can last 25 to 40 years, depending on operating conditions and load demands.

9. How are pole-mounted transformers installed?
   They are mounted on sturdy poles using brackets and connected to overhead power lines, with proper grounding for safety.

10. What are the common issues with pole-mounted transformers?
    Common problems include oil leaks, overheating, insulation degradation, and damage from environmental factors like storms or lightning.
