Motors and Variable Speed drives
By Colin Hargis / Published on Mon, 2007-02-19 12:35 On page 8 one of the "contras" for VSD is given as "sensitive to voltage dips". There is no intrinsic reason why a VSD should be any more sensitive to dips than a directly-connected motor, and in fact if configured correctly the VSD can contribute to a well-controlled and co-ordinated reaction to a power dip or interruption. It can make use of the mechanical stored energy in the load, and a three-phase drive can ride through the loss of one phase for a time only limited by thermal constraints. If VSDs are perceived as sensitive to voltage dips then this is a problem for their manufacturers, and suggests that we need to pay more attention to good quality user-oriented commissioning instructions to ensure they are set up correctly for the application, with due attention paid to their power-dip behaviour.
