Data record instr.series-resonant-test-system.tuning-variants

Verified 2026-10-27 Confidence: Medium

Resonance is reached either with a variable-inductance reactor whose core gap is moved at a fixed power frequency, or with a fixed reactor fed by a frequency converter that varies the frequency until resonance is found; the fixed-core variable-frequency design is lighter and more powerful for the same rating.
