Summary: This standard specifies with brake (percentage) differential relay performance requirements. These relays constitute such 60255-6 (Electrical relays Part 6: Multiple input energizing quantity Measuring relays) defined multiple input energizing quantity measuring relays especially the family, them parameters from these relays provide manufacturers. The standard also provides a description of these relays features and performance methods. This standard applies to pre- testing, especially detection alternators, AC motor, transformer failure relay. It does not apply for busbar protection relay, does not apply to Transmission Line Protection current differential (eg guide wire) relay. This standard outlines the most with brake (percentage) differential relay, but also includes those such as braking ratio increases with the increase of cross currents relay. For some special cases, their supplementary requirements may be appropriate standards.
