IDMTL Overcurrent Protection (ANSI 51) - Schneider Electric

NettetInstantaneous Protection (ANSI 50) Introduction. Instantaneous protection protects all types of motor applications against very high intensity short-circuit currents. Operating Principle . Instantaneous protection is fixed: the pickup value is determined by the current rating In. Protection is instantaneous. NettetGrading with the protection relay directly behind the protection relay, which has the instantaneous devices enabled, is accomplished at the current setting of the instantaneous devices and not at the maximum short circuit level.
