| Title | Part 21 - Loose Connection on Egp/Etr Series Relays |
| Event Description | The following is a summary of information received from TE Connectivity via fax:
During Management of Change review on 7/23/21, TE Connectivity discovered test load was unconnected to HI-POT tester for EGP/ETR series relays. TE's investigation found a connection remained loose after scheduled calibration testing on 12/30/2020. This report serves to document TE's evaluation and the corrective action taken on this issue: 1. A search of TE's database finds no occurrence of Dielectric Withstand Voltage (DWV) test failure at TE facility or similar failure with our customers in the field. 2. Many nuclear customers perform thorough inspections and testing prior to installing relays. 3. No customer history of EGP/ETR complaints of DWV failures found. 4. A series of corrective actions are now in place to guarantee full DWV testing to specification including: a mistake proof HI-POT test fixture developed and installed, and Hi-Pot test setup verification included as part of testing routine. There have been no reported field failures for the identified impacted produce. However, out of an abundance of caution TE will notify customers of the issue and the option to return any relays potentially related to this issue for retesting and recertification.
