Transformer Protection Relay T-PRO 4000 Product Overview The IEC 61850 station bus embedded T-PRO 4000 relay provides complete three-phase multi-winding transformer fault and overload protection, DFR-quality fault oscillography, fault logging, sequence of event logging, trend recording, transformer monitoring and overload early warning (TOEWSTM) integrated with advanced communications in a flexible, cost effective package. Apply the T-PRO 4000 system for high speed protection and complete control of multi-winding transformers with the HV and LV windings connected to ring or breaker-and-a-half arrangements. • Easy-to-use, intuitive setting and analysis software • IEC 61850 communication via optical/copper ports • Internal magnitude and phase shift compensation, eliminating requirements for external CT connections and auxiliary CTs • 2nd and 5th harmonic restraint algorithm that improves security for energization, inrush and overfluxing • THD alarm function that alerts to the degree of current waveform distortion and therefore harmonic content • Asset management to maximize use of transformer capacity (ANSI/IEEE C57.91-1995) • Through Fault Monitoring function to measure the duration, current peak RMS and accumulated I2t values for each phase during through fault (use this information for analysis and preventive maintenance planning) • Ambient Temperature Adaption (ADP) adjusts the pickup level of the time overcurrent protection (51HV) based on the ambient temperature • High quality fault recording, trending and event log • 8 setting groups to accommodate for various operating conditions • Ethernet ports with 2 unique MAC addresses accommodate network access security needs

Application • Primary and back-up protection, and management of small, medium and large power transformers, and reactors. • Transformer asset monitoring using thermal overload based on hottest spot or top oil temperature, Transformer Overload Early Warning System (TOEWSTM), and Through Fault Monitoring1 • Applicable for transformers installed in substations with bus bar arrangement in a ring bus or breaker-and-a-half configuration Protection & Control • Protection functions include IEEE devices 87, 87N, 49, 67, 50/51, 50N/51N, 51ADP, 50BF (each winding), 24INV/DEF, 59N, 59, 60, 81U/O, THD, 27,...
