Im using siprotec 7SJ66 relay for feeder protection. the same relay is used for over voltage protection. PT used is 33/kV110V. Proble is that Fedder gets trip due to higher voltage in grid.but Even the grid voltage lowers the over voltage limit , the relay doesnot reset automatically. System:- 33kV. PT used :-33kV/110V Technical Manual Chapters 1. Description of Operation 2.

The corresponding device driver for 7SJ66 V4.3 has also been installed in the Laptop. However, when trying communication of new 7SJ66 relay with laptop through the relay's front USB port and an straight male-male USB cable, the laptop is not detecting the relay. The SIPROTEC 7SJ64 can be used as a protective control and monitoring relay for distribution feeders and transmission lines of any voltage in networks that are earthed (grounded), low-resistance earthed, unearthed, or of a compensated neutral point structure.
