LAPCO-HF 6028

differential over current relay LAPCO-HF6028

Features

  • Differential Protection – 2 windings (87T)
  • Restricted Earth Fault Protection (87N)
  • Definite-time Overcurrent Protection (50 P/Q/N)
  • Inverse-time Overcurrent Protection (51 P/Q/N)
  • Disturbance Recording

The LAPCO-HF 6028 differential protection device provides a fast and selective protection of sub-transmission transformers with two windings. Comprehensive integrated back-up protection functions such as time Restricted Earth Fault and overcurrent protection make additional protection devices obsolete.
