Abstract
frequency dependence of the Kerr constant K in transformer oil Nynas Nytro 3000 within a frequency range 117-5017 Hz is determined. An averaged value (2.30 ± 0.03)·10-15 m/V2 for K is obtained. The constant is found to be weakly frequency dependent and approaches its maximum 2.37·10-15 m/V2 at about 3000 Hz. The Kerr constant is of comparable value to that observed in other mineral oils employed previously in measurements of the quadratic electro-optic effect and the electrostriction in crystals.
