View all IEDs

Main functions

  • Phase-segregated current differential protection (87B)
  • Undervoltage based fault detection (UV/UVS/UVD)
  • Overcurrent protection (50BF) for circuit breaker failures
  • CT and PT failure detection and alarming
  • External fault detection to prevent wrong tripping due to CT saturation
  • Busbar-bridged protection according to the status conditions of DS's and alarming for abnormal conditions
  • Automated compensation for different CT ratios
  • Communication with multiple BUs based on high speed serial communication (1Gbps, fiber optic)
  • Fully IEC 61850 compliant, Edition 1
  • Self-monitoring on a regular basis
