Advantages of line differential protection relay RED670/650

Hitachi Energy provides RED670/RED650 line differential protection solution with high sensitivity and speed, meeting all protection requirements for transmission lines from 110kV, 220kV, 500kV overhead and underground cables.

  • The 87L differential protection function has a fast speed, a trip time of less than 1 cycle (one of the fastest and most sensitive relays available today).
    Integrated parallel working distance protection function with differential protection function in 01 relay.
  • Built-in protection functions 59/27, 24, 81, 68, 50/51, 50N/51N, 67/67N, 32…
  • LDCM communication card used for different differential protection function: Short range, Medium range, Large range; allows the use of both direct optical communication methods, as well as optical communication over the transmission channel system.
  • Support LDCM card communication speed: 64kbps capable of sending 03 Analog & 3 Binary or 192 Binary signals; 2Mbps is capable of sending 09 Analog & 192 Binary signals.
  • Easy integration with traditional substation protection systems and digital substations.
  • There are 06 groups that allow protection configuration for all types of line protection schemes.
  • Fully integrated IEC 61850, Edition 1 and Edition 2 communication protocols.
  • The maximum number of Analog input channels is up to 24AI (RED670) and 12AI (RED650), allowing protection of all types of transformers from simple modal diagrams to complex modal diagrams.
  • Analog input channels are used to configure flexibly, allowing users to customize their use according to CT/VT channels.
  • The hardware of the relay lines in the Redlion 670 product line works on the same platform, so users can use both the hardware of the relay lines together, helping to optimize repair and replacement costs, and ensure operation. Flexible, simple.
  • RED650 has a small size ½ 19inch with integrated 12AI, suitable for protection with simple, cost-effective method diagrams for the upgrade process.
  • The RED670 is available in ½, ¾, 1/1 19inch sizes and integrates up to 24 Analog inputs suitable for protection of complex modal schemes.
  • The number of Binary inputs and Binary outputs is large, reaching a maximum of 96 BO and 112 BI.
  • The trip time of the 87L differential protection is only about <20ms, which is one of the fastest differential protection relays available today.
    PCM600 configuration software is compatible with Windows 10, 11 operating systems.
  • Diverse, high-speed connections according to current electrical industry standards:
+ IEC 61850-8-1.
+ IEC 62439-3 (PRP).
+ IEC 62439-3 (HSR).
+ IEEE 802.1D (RSTP).
+ IEC/UCA 61850-9-2LE hỗ trợ 8 MUs.
+ IEEE 1344.
+ IEC/IEEE 60255.118 (C37.118).
+ IEC 60870-5-103, DNP 3.0, SPA, LON.
