CEI/IEC 60076-13:2006 Power transformers. Part 13. Self-protected liquid-filled transformers

First edition. — IEC, 2006. — 44 p.International Standard IEC 60076-13 has been prepared by IEC technical committee 14:
Power transformers. This part of IEC 60076 applies to high-voltage/low-voltage self-protected liquid-filled and naturally cooled transformers for rated power 50 kVA to 1 000 kVA for indoor or outdoor use having a
– primary winding (high-voltage) with highest voltage for equipment up to 24 kV;
– secondary winding (low-voltage) with highest voltage for equipment of 1,1 kV.
These transformers are equipped with a self-protection and disconnection device to protect the environment, property and people and prevent any disturbance of the high-voltage network from the consequences of an internal transformer fault.
