Application Scenarios / Pain Points
-
Protection systems require correct PT source selection in dual-bus or 3/2 wiring configurations.
-
Conventional switchers cannot automatically transfer based on isolator position, leading to misoperation.
Our Solution
-
Dual-bus PT switching relays automatically transfer voltage based on isolator position. safe testing/isolation.
-
PT paralleling and isolator reclose relays to ensure reliable source transfer.
-
Automatic PT transfer devices for 3/2 bus configurations.
