Product Description
Scheider Advanced transformer Protection and Control
Transformers are high capital cost assets in electrical power systems. Elimination of all electrical and mechanical stresses, although desirable to
Preserve transformer life, is impractical. Adaptive techniques to measure and alarm (or trip) in such instances, and advise on cumulative service duty, can help to schedule preventive maintenance before a costly failure occurs.
Internal faults are a risk for all transformers, with short-circuits dissipating
The highest localized energy. Unless cleared quickly, the possibility to
Rewind windings reduces, and core damage may become irreparable. The MiCOM P642, P643 and P645 address all these issues - preserving service life, and offering fast protection for transformer faults. Hosted on
An advanced IED platform, the P64X incorporates differential, REF, thermal, and overfl uxing protection, plus backup protection for uncleared external faults. Model variants cover two and three winding transformers (including autotransformers), with up to 5 sets of three-phase CT inputs. Large CT counts are common in ring bus/mesh corner applications, where the P64X summates currents to create each total winding current, easing application of backup protection. Backup overcurrent can be directionalized, where the user includes the optional 1 or 3-phase VT input in their chosen model.
