Safety interlocks are the last line of defense against dangerous switching sequences in medium-voltage (MV) switchgear. This video breaks down “Five-Prevention” logic and shows how permissive chains work in real panels—linking breaker status, truck position (service/test/isolated), earthing switch status, door access, and voltage indication.
You’ll learn:
The 5 misoperations that interlocks are designed to block
How DSN (electromagnetic lock) and DXN (voltage indication) fit into the interlock chain (project-dependent naming)
A practical permissive/state-matrix approach for commissioning and troubleshooting
Field checks that help prevent bypass culture and false-safe indications
If you need an interlock review or a testable permissive matrix for your lineup, contact XBRELE.
