The electrical conductivity σ (T) and thermoelectric power S(T) measurements of Sr₂InV₃O₁₁ showed the insulating state and the change of sign of thermopower from p to n at T_{n-p}=400 K. The I-V characteristics provided the evidence of symmetrical and non-linear behaviour typical of strong emission of charge carriers induced by temperature and voltage. Relative dielectric permittivity ε_{r} as well as loss tangent (tan δ) strongly depend both on the temperature in the range of 295-400 K and the frequency in the range of 5×10² to 1×10⁶ Hz, showing the broad maximum at 320 K. These effects are considered as a relaxation process like in the Maxwell-Wagner or Jonscher model as well as the conduction of electric current, as determined by the Joule-Lenz law.
