Product Description

SIEMENS SIPROTEC 7SL86 LINE DIFFERENTIAL AND PROTECTION NUMERICALRELAY

The combined line differential and distance protectionSIPROTEC 7SL86 is part of the new SIPROTEC 5 series of modular, flexible andintelligent digital field devices. With its modularity and flexibility and itshigh-performance DIGSI 5 engineering tool, the SIPROTEC 7SL86 fits perfectlyfor protection, control, monitoring, and measuring applications in electricalenergy systems.Main function: Differential and DistanceProtectionTripping:3-pole, min. tripping time 9 msInputs and outputs:-12predefined standard variants with 4/4 or 8/8 current/voltage transformers, 5 to31 binary inputs, 8 to 46 binary outputs Hardware flexibility: Flexiblyadjustable I/O quantity structure within the scope of the SIPROTEC 5 modularsystem Width of housing:1/3 x 19'' to 2/1 x 19''

All functions can be configured freely with DIGSI 5. For theapplication of some of the functions, you require the appropriate number offree function points within the device. The function point calculator in theonline configurator provides support in determining the required number offunction points for your device.

  • Minimal tripping time: 9 ms
  • Main protection function is differential protection with adaptive algorithm for maximum sensitivity and stability even with the most different transformer errors, current-transformer saturation and capacitive charging currents
  • Several distance-protection functions selectable as backup protection or secondary main protection: Classic, reactance method (RMD), impedance protection for transformers
  • Directional backup protection and various additional functions
  • Adaptive power-swing blocking, out-of-step protection
  • Detection of ground faults of any type in isolated or arc-suppression-coil-ground systems using the following functions: 3I0>, V0>, fleeting contact, Cos-/SinPhi, harmonic, dir. detection of intermittent ground faults and admittance
  • Ground fault detection using the pulse location method
  • Detection of current-transformer saturation for fast tripping with high accuracy
  • Arc protection
  • Reactive power-undervoltage protection (QU protection)
  • Detection of current and voltage signals up to the 50th harmonic with high accuracy for selected protection functions (such as thermal overload protection) and operational measured values
  • 3-pole automatic reclosing function
  • Control, synchrocheck and switchgear interlocking protection
  • Graphical logic editor to create powerful automation functions in the device
  • Single line representation in small or large display
  • Integrated electrical Ethernet RJ45 for DIGSI 5 and IEC 61850 (reporting and GOOSE)
  • Up to 4 optional pluggable communication modules, usable for different and redundant protocols (IEC 61850, IEC 60870-5-103, IEC 60870-5-104, Modbus TCP, DNP3 serial and TCP, PROFINET IO)
  • Serial protection data communication via optical fibers, two-wire connections and communication networks (SDH networks, MPLS networks, for example using IEEE C37.94, and others), including automatic switchover between ring and chain topology
  • Redundancy protocols PRP and HSR
  • Cyber security to NERC CIP and BDWE Whitepaper requirements
  • Phasor Measurement Unit (PMU) for synchrophasor measured values and IEEE C37.118 protocol
  • Time synchronization IEEE 1588
  • Powerful fault recording (buffer for a max. record time of 80 sec. at 8 kHz or 320 sec. at 2 kHz)
  • Auxiliary functions for simple tests and commissioning
  • Flexibly adjustable I/O quantity structure within the scope of the SIPROTEC 5 modular system
