The choice of a protection scheme for alternators or motors must take into account a number of parameters, including :
the role and importance of the machine within the plant of which it is a part (power generation unit, industrial plant, factory);
the cost of repair in the event of damage and the costs incurred (e.g. for immobilization of the associated industrial process), or even the cost of replacement with new equipment;
the compromise between achieving a good level of reliability for the protected machine and the risk of untimely operation (tripping) of a protection, a risk which increases with the number of protection functions implemented.
For example, in certain applications where continuity of service is essential, it may be acceptable...
