Medium-voltage switchgear contains dozens of critical components beyond the circuit breaker: epoxy insulators, busbars, interlocks, voltage sensors, earthing switches, cable…
Switchgear safety depends on knowing whether circuits are energized before maintenance work begins. Visual inspection cannot distinguish between 12 kV…
Transformer voltage regulation capability ranks among the most consequential decisions in procurement. The choice between an on-load tap changer (OLTC)…
Vacuum interrupter contact wear is the primary factor determining when a vacuum circuit breaker reaches end-of-life. Systematic measurement of contact…
Partial discharge in epoxy insulation refers to localized electrical breakdown within gas-filled voids or defects that does not fully bridge…
Vacuum circuit breaker commissioning failures don’t announce themselves during factory acceptance tests. They surface at site energization when auxiliary contacts…
Medium-voltage equipment fails when insulation distances are wrong. Not dramatically—just silently enough that the failure surfaces months after commissioning, after…
Tulip contacts are the separable, high-current interface used in drawout MV equipment: the moving primary stab mates into a spring…
What “Safety Interlocks” and “Five-Prevention” mean in MV switchgear A safety interlock in medium-voltage (MV) switchgear is an engineered permission…
