Power Transmission Lines and Substations

1. Tirana 220kv/110KV/35kv substation restructure Project

1.1 The introduction of construction
The project is built to reinforce the 220 KV Tirana substations, Albania . The substation has three sets of autotransformers and will reinforce another one through this project.
1.2 The description and value of main autotransformer
Type of autotransformer:
　 Capacity: 120/120/60 MVA
　 Voltage: 220 + 8x1.25% /115/37.5 + 2x2.5% KV
　 Method of connection: Y0-o/ Δ
The continual working current:
　 220 KV side: Ig 1 =0.331 KA
　 110 KV side: Ig 2 =0.662 KA
　 35 KV side: Ig 3 =0.971 KA
