Data record instr.circuit-breaker-analyzer.both-sides-grounded

Verified 2026-10-27 Confidence: High

Timing can be done with both sides of the breaker grounded; the analyzer then senses contact operation by a dynamic capacitance measurement across the grounded contacts rather than by a voltage across open contacts, which removes the hazard of induced voltage in high-voltage substations and makes gas-insulated switchgear testable without altering its connections.
