'ALSTOM' Protection Relay MODEL NO:- P94VP16A7C0540A; Advanced Transformer Protection, Control and Condition Monitoring Transformers are high capital cost assets in electrical power systems. Internal faults are a risk for all transformers, with short-circuits dissipating the highest localised energy. Unless cleared quickly, the possibility of rewinding will diminish and core damage may become irreparable.The MiCOM Agile P642, P643 and P645 address all these issues - preserving service life and offering fast protection for transformer faults. A transient bias technique has been included, enhancing relay stability and CT requirements. CT saturation and no gap detection techniques have been included to improve the low set differential element operating time during CT saturation where the second harmonic blocking might be asserted. An external fault detection algorithm has been incorporated to prevent the CT saturation and no gap detection from affecting the second harmonic blocking .
