Transformer surveys

Large oil filled transformers used on the electrical grids remain in operation and at temperature, for many years causing the internal components to degrade over time. Since the internal condition is unknown, to manage risk, they are replaced at great cost, long before operationally failing. Gnosys have developed an in-situ method of conditionally assessing transformers and analysing the degree of degradation enabling the operator to extend the life and reduce costs.
