A new ATP add-on for modeling internal faults in power transformers Conference Paper

abstract

• A transformer model and its software implementation capable of modeling internal winding-to-ground and turn-to-turn internal faults in three-phase multiwinding transformers and autotransformers is presented. The method represents a transformer by coupled-RL coils and adds an internal fault model by sub-dividing the windings into sub-coils and appropriately calculating the parameters of the new coils. The stand-alone executable software was developed that supports both the data preparation for the BCTRAN of ATP as well as creation of the transformer model with an internal fault. The software can be used as an add-on with ATP or in conjunction with advanced modeling and testing tools for short-circuit related activities.
