Transformer Differential Settings: Transformers are critical substation components that need sensitive protection. Relay protection for transformers involves calculations for differential current thresholds, through-fault stability, inrush restraint, and harmonic filtering to. Provide current diferential protection for up to five windings with an adaptive-slope percentage restraint for transformers at power plants, transmission substations, distribution substations, and industrial plants. Table below lists failures for six categories of faults (acc. 1): Winding and tap changers account for 70% of failures. In some cases, a user may apply the techniques described in this guide for protecting. Some sections are written specially for this handbook some are from old informations, lectures etc.
