Superior protection performance is combined with integrated station automation features for seamless transition into new and retrofit applications. SEL SV merging units (or other IEC 61850-9-2 SV-compliant units) digitize signals and transmit them via Ethernet over fiber-optic cables to an SEL-487B-2 SV relay in the control house Page 1 32 programmable ele- ments and voltage elements provide additional pro- ments for local control, remote control, protection tection for the capacitor bank

SOLUTION Sel 487e transformer protection relay testing procedures. The SEL-2600 RTD Module provides as many as 12 temperature inputs, and Apply up to 5 three-phase restraint inputs, three independent restricted earth fault protection elements, and 2 three-phase voltage inputs, all with synchrophasors

SEL487E Transformer Differential Relay. Distributed Bus Protection Apply the SEL-487B in a distributed bus protection scheme using TiDL technology. SEL SV-Based Solutions Based on the IEC 61850 standard, SV-based solutions maximize flexibility and interoperability
