Sel 487e relay serial#
You can use synchrophasors over serial or Ethernet communications to easily detect reactive loop flows, turn state estimation into state measurement, and provide an early warning of potential system instability. Station Phasor Measurement Unit (PMU)-Improve power system quality with SEL synchrophasors (IEEE C37.118) from all 24 analog channels (6 voltage and 18 current sources) in your relay. The SEL-487E can monitor substation dc power systems for out-of-tolerance voltage levels or excessive voltage ripple. Advanced breaker monitoring helps reduce inefficient and costly breaker maintenance.

Generator Step-Up Protection-Protect generator step-up (GSU) transformers, and apply the built-in thermal elements (requires the SEL-2600 RTD Module) for monitoring and protecting generator and transformer winding temperatures simultaneously.Īdvanced Asset Monitoring-Track transformer wear with through-fault and thermal monitoring. With a typical two-winding transformer application, you can use the remaining three-phase current inputs for feeder backup protection. The adaptive differential element responds to internal fault conditions in less than 1.5 cycles.ĭiverse Transformer Applications-Protect large transformers with breaker-and-a-half high- and low-side connections. High-Speed, Adaptive Differential Protection-Implement a two-stage slope that automatically adapts to internal or external fault conditions, even with CT saturation and heavily distorted waveforms, for fast, sensitive, dependable, and secure differential protection. Sensitive Turn-to-Turn Fault Detection-Avoid catastrophic transformer failure by detecting turn-to-turn faults involving as little as two percent of the total winding with the patented negative-sequence differential element. You can invert individual or grouped CT or PT polarities to account for field wiring or protection zone changes. Three independent REF elements provide protection of grounded-wye windings. This includes single transformers with tertiary windings. Multiwinding Protection-Configure the SEL-487E for transformer differential protection in transformer applications using up to five restraint currents. Optional Time-Domain Link (TiDL) technology and SEL Sampled Values (SV) technology using IEC 6 transform the way you modernize your substation. Breaker wear monitoring reduces inefficient and costly breaker maintenance, saving time and money. Through-fault and thermal monitoring allow you to track transformer wear and schedule maintenance as necessary. You can minimize commissioning time and eliminate costly errors with included software that recommends matrix compensation settings. The relay also helps avoid catastrophic transformer failure by detecting turn-to-turn faults involving as little as 2 percent of the total winding. The SEL-487E limits transformer damage by responding to internal fault conditions in less than 1.5 cycles. It offers up to five three-phase restraint inputs, three independent restricted earth fault (REF) protection elements, and two three-phase voltage inputs, all with synchrophasors. relay instruction manual, the user's guide and the application guide havenondedicated CTs with the SEL-487B Bus THE SEL-487B IS A POWERFUL SOLUTION FOR THE DIFFERENTIAL Differential element operation in less.Protect and monitor most transformer applications with the powerful SEL-487E.
