1.	What is the additional usage of the presspahn material used as insulation material?(a) lamination(b) to reduce the losses(c) to protect secondary winding conductor from mechanical damage(d) to protect secondary winding conductor from electrical damageI have been asked this question in an online quiz.This intriguing question originated from Current Transformers Construction in section Design of Current Transformers (CT) of Design of Electrical Machines
Answer» Right option is (c) to protect secondary winding CONDUCTOR from mechanical damage The best EXPLANATION: The PRESSPAHN is USED as INSULATING material in the current transformer. In addition to that the presspahn is also used to protect the secondary winding conductor from mechanical damage.
