Description
This information notice is being provided to alert recipients to potential problems involving HFA, PVD 21B, PVD 21D, and HGA relays manufactured by General Electric Company (GE), as described below. Although some of these problems are several years old, they are included because utilities are still identifying problems discovered while implementing advice issued by GE in the early 1980s. The specific problem with the HFA relays concerns mechanical binding in the relay caused by incorrect location of a stop tab that is welded to the armature. The problems with the PVD 21B, PVD 21D, and HGA concern their seismic capability
