A 1 KVA transformer on a 11KV system sounds rather small ! to run neon lights ?Then more like 100 KVA

It sounds like you are trying to set up your own electrical grid, from the ground up?Hello
But I agree with Alan and Chris - get an experienced and licensed person to do it.
I studied the theory at university, then got some practical experience in the industry. But if you want people to have electrical power (and not be killed by it), get someone who has the appropriate qualifications, and knows the standards and regulations for your country. Different countries have different practices, and even different areas of the same country have different practices, depending on the resistivity of the rock, for example.
In selecting the right transformer, you need to know:
- What is the common voltage and frequency in your country; common values are 230VAC at 50Hz and 115/230VAC at 60Hz in North America (Japan has both systems!)
- Is it a 2-phase or 3 phase Low Voltage distribution?
- How much power will be drawn?
- What is the distribution voltage in your area? These are often in the region of 11kV
- Is the distribution system star or delta/wye? (as Syphrum mentioned)
- What type of fuses or circuit breakers will be used on the supply side and subscriber side?
- How will you check the oil purity and replace the oil periodically?
