A theoretical analysis of variations in the propagation velocity of ultrasonic waves in liquid dielectrics in an external DC electric field was performed. Measurements of these variations in transformer oil in dependence on the field strength and temperature were made applying the phase method. To express the experimental results in graphical form numerical procedure of interpolation in Lagrange polynomials was used. The experimentally obtained variations in the velocity are compared with those predicted theoretically by the formulae derived.
