“…Finite Element Modelling (FEM) is being widely used by transformer manufacturers during the design stage to study the magnetic flux distribution, losses, and structural health [13][14][15][16]. However, existing literature state that FEM simulations can be used not only during manufacturing process but also to understand the behaviour of field installed transformers [12].…”

Power transformer condition monitoring is an important topic in both research and practice. However, condition monitoring of power transformer winding clamping system is rarely discussed. As a result, no reliable condition monitoring technique has been developed to assess the condition of power transformer winding clamping system. However, Finite Element Modelling (FEM) based simulations can be utilised to understand the complex behaviour of winding clamping structure under different operating conditions and then acquired knowledge can be used to improve the accuracy of existing condition monitoring techniques. Therefore, this study reviews the research status in use of FEM based simulations in condition monitoring and diagnosis of power transformer winding clamping system.

There are a number of secondary effects in a synchronous machine which are most often neglected to develop a simplified model. This procedure is simple and straight-forward, but it gives rise to much errors. To avoid the errors, the modelers have developed several techniques. Saturation is one of the secondary effects which become quite dominant at certain load conditions. In the earlier regimes, grapho-analytical techniques were developed to treat the effect of saturation. But such methods were tedious, complex and time-consuming. Now they should be replaced by computer methods. This paper gives a comprehensive discussion on the various methods developed to treat the effect of saturation. It also gives computer-aided methods to replace the older methods.
