Integrated Solution: Pad Mounted Transformers Enhancing Efficiency and Reliability in Distributed Solar PV Systems
1. The Core Role of Pad Mounted Transformer (PMT) in Distributed PV SystemsA Pad Mounted Transformer (PMT) is a fully sealed, box-type transformer installed directly on a ground-level concrete pad (pad). It is suitable for voltage step-up and grid interconnection in distributed photovoltaic (PV) power plants. Its primary functions include: Voltage Transformation:Steps up the low-voltage electricity output from PV inverters (e.g., 0.8kV) to 10kV or 35kV to meet grid interconnection requirements.
