Optimum transformer design and operation within capability to prevent damage.
The project will deliver tools to analyse what happens to plant with a magnetic circuit when that circuit starts to become saturated because of extreme operating conditions. Examples of this are transformers under ferroresonant conditions, transformers subject to DC currents such as during geomagnetic (GIC or sun storm) events, series reactors under fault conditions and quadrature boosters under high load conditions. Failure to properly analyse these conditions leads either to excessive capital cost in increasing core dimensions, or potential failure in service due to the heating of the magnetic circuit and other steel parts in the transformer or reactor.
