Data record instr.vacuum-interrupter-tester.purpose

Verified 2026-10-27 Confidence: High

A vacuum interrupter tester checks whether the vacuum inside the sealed interrupter of a medium-voltage circuit breaker is still intact, and therefore whether the breaker can still interrupt a fault current; the interrupter is tested in place without dismounting it from the breaker.
