I want to design the installation of a 500KVA Distribution Transformer to supply a neighborhood in Nigeria. The Existing National Grid voltage is 11KV. I want input from you guys to add to my sizing/costing. Inputs: 1. Sizing of XLPE Cable 2. Sizing of Transformer HV Protection ( Current Rating of J & P Fuse ) 3. Sizing of Transformer Body and Neutral Earth Cable 4. Sizing of Armoured Cable from Transformer LV to Feeder Pillar 5. Sizing of Feeder Pillar Amperage 6. Sizing of Current per Feeder/Circuit emanating from the Feeder Pillar 7.Sizing of Upriser Armoured Cable 8. Sizing of Feeder Pilllar HRC Fuse Amperage 9.Sizing of Feeder Pillar Earth Cable 10. How many earth pit needed in the distribution station? 11. Transformer primary and secondary current 12. Transformer Maximum Fault Current 13. Current per phase 14 How to balance consumers load per phase of the transformer I look forward to hearing from you guys. Thanks.
