Abstract: In this paper, we investigate the oscillation of a conformable fractional three dimensional nonlinear partial delay differential system. We establish some new oscillation criteria of the solutions of the differential system by using the generalised Riccati transformation and the integral averaging method. The obtained results are illustrated by various examples.

Keywords: oscillation; delay; partial differential system; conformable fractional derivative.
