Measuring relays and protection equipment - Part 187-3: Functional requirements for differential protection - Line current differential protection

Abstract

IEC/TC 95 had decided to revise IEC 60255-13 and replace it with IEC 60255-187-3. IEC 60255-13 specifies the performance requirements of electrically biased (percentage) differential relays as well as methods of presenting the characteristics and performance of these relays. Applies to relays in a new condition designed for the detection of faults particularly in a.c. generators, motors and transformers. All tests are type tests. Does not apply to relays designed for busbar protection, nor applies to current differential relays used for the protection of transmission lines.
