From the perspectives of no-load loss, load loss, and total cost of ownership, we analyze the selection logic and recovery period calculation method for upgrading from S13-M to energy-efficiency level 1 S20/S22.
S13-M-1000/10 oil-immersed power transformer, 1000kVA, 10.5/0.4kV, Dyn11 connection, no-load loss ≤870W, suitable for high-temperature, sandy conditions in the Middle East and salt-spray, humid environment in Southeast Asia, providing a full set of IEC 60076 test reports.
