The quality of two different separable expansion methods (\sl W matrix and Ernst-Shakin-Thaler) is investigated. We compare the triton binding energies and components of the triton wave functions obtained in this way with the results of a direct two-dimensional treatment. The Paris, Bonn \sl A and Bonn \sl B potentials are employed as underlying two-body interactions, their total angular momenta being incorporated up to j ≤ 2. It is found that the most accurate results based on the Ernst-Shakin-Thaler method agree within 1.5% or better with the two-dimensional calculations, whereas the results for the \sl W-matrix representation are less accurate.
