This part of IEC 60076-22 applies to electric pumps mounted on liquid immersed power transformers according to IEC 60076-1 and reactors according to IEC 60076-6 with and without conservator for indoor or outdoor installation. It outlines the operation requirements for the electrical and hydraulic performance, mechanical design, routine testing and type testing. Additionally, performance and dimensions of preferred sizes of pump sets are specified in informative annexes. (See Annex A and Annex B). The pumps covered in this standard are rotodynamic pumps driven by a squirrel cage induction motor that is immersed in the insulating liquid. Pump sets conforming to this standard can be of in-line or end suction design.
