About Henries
The henry (H) is the SI derived unit of electrical inductance, equal to 1 volt-second per ampere (1 V·s/A = 1 Ω·s = 1 kg·m²·A⁻²·s⁻²), named after Joseph Henry (1797-1878). Mains-frequency (50/60 Hz) power transformers have primary inductances of 1-100 H; loudspeaker crossover woofer inductors are 1-5 mH; large power-line reactors are 0.1-10 H. 1 H = 10³ mH = 10⁶ µH.
About Kilohenries
The kilohenry (kH) equals 10³ H, encountered in the inductance of very-low-frequency (VLF) antenna loading coils and large power-system shunt reactors. Submarine communication transmitters at 10-30 kHz use loading coils of 100-2 000 H = 0.1-2 kH; high-voltage shunt reactors in 400 kV grid substations have inductances of around 100-1 000 H = 0.1-1 kH. 1 kH = 10³ H = 10⁻³ MH.
