Understanding the dynamics of galaxy triplet systems is one of the significant ways of obtaining insight into the dynamics of large galaxy clusters. Towards that aim, we present a detailed study of all isolated triplet systems (total of 315) taken from the 'SDSS-based catalogue of Isolated Triplets' (SIT). In addition, we compared our results with those obtained for a sample of triplets from the Local Supercluster, SDSS-triplets, Tully's catalogue, Wide (W) and Compact (K)-triplets. In addition, we performed the correlation between the dynamical parameters and the large-scale structure (LSS). Interestingly, we found that there is no correlation between both the mean projected separation for the triplet systems and the LSS and its dynamical parameters. Furthermore, we found that only 3 per cent of these systems can be considered as compact since the mean harmonic separation (r_h) is more than 0.4 Mpc for 97 per cent of the population. Thus, we may conclude that mergers might not have played a dominant role in their evolution.
