WHAT HAPPENED HT MOTOR FEED WITH LT SUPPLY

3919

A double circuit with dog conductor 66KV Transmission line from wind farm evacuation to feeding substation having capacity of 25MW for transmission. Can same transmission network be considered for further expansion of Power & how much in MW. If we need to expand next 10-15 MW more will there any augmentation is required in transmission network? Kindly reply asap.

y we use neutral,all r told its used to for closed path..k its a just used to closed path,in a transmission line y we put same conductor used n both phase and neutral..if we use less than phase conductor in neutral mean we ll reduce cost its right r wrong..if we use mean any problem occur in transmission line..
