Check out the GS-1500N demonstration at the State Grid Substation

GS-1500N can scan the detailed internal structure of the substation at both 200m and 300m altitude. The main network ground lines and insulator structures are clearly continuous, and even the 10kv distribution network lines are fully restored.
With its long range and high precision, GS-1500N makes working on the power grid stress-free and eliminates the need for rework.
