Description
Standard HV voltages are 15.75 kV, 20 kV, 21 kV and 22 kV. The LV side is built for 800/462, 690/398, 420/242 or 400/231 V to match the inverter output voltage. Cooling is ONAN, ONAF, KNAN or KNAF. The transformer is placed between the inverters and the HV grid. The transformers comply with STN EN 60076 and EN 50708.
