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.

Distribution transformer we provided 2 separate earthing pit for Body and 2 separate earthing pit for neutral,we can not connect separate body earthing pit to other earthing pit but we do metal glanding in secondary side cable termination in both side, transformer and PCC panel (LT Panel), is this safe for transformer and other equipment?
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..
