The electric and luminous characteristics of low-frequency inductive discharge of transformer type (IDTT) in mercury vapor were studied experimentally for different parameters of the discharge: mercury vapor pressure in the discharge chamber and the input power of the discharge. The energy distribution over the spectral range of 250 - 600 nm and volt-ampere characteristics were measured for the following discharge parameters: power 2 - 100 kW (specific power 10 - 500 W/cm), mercury vapor pressure 2 - 40 kPa. The IDTT characteristics were analysed using a U-like channel model for axisymmetric thermal arcs; the results were compared with characteristics for regular arc discharge in mercury vapor. The dependency of key electric and luminous characteristics of IDTT on the discharge parameters is very close to those for mercury arc discharge.
