A zone 3 distance relay is utilized to provide remote backup protection in the event that the primary protection fails. Second, neural network models do not admit a mathematical or computational description that is at once transparent and precise, so it is difficult to understand their behavior except phenomenologically, by looking at results such as misclassification tables. Neural networks are based either on the study of the brain or on the application of neural networks to artificial intelligence. There are however many neurons in a single layer and many layers in the whole network, so we need to come up with a general equation describing a neural network.
