Model 4000-SV
Recording for a fully digital substation environment

Now with IEC 61850 Sampled Value support!
TESLA 4000-SV Recorders with IEC 61850 Sampled Values Subscription

Application using IEC 61850 in Digital Substations

  • Lower Installation Cost - quickly exchange data over the station LAN without wiring separate links for each relay
  • Lower Extension Costs - add devices and applications into an existing IEC 61850 system with minimal impact, if any, on existing equipment
  • Lower Integration Costs – to integrate substation data into the enterprise, use same networking technology widely used across the utility

TESLA 4000 provides support for IEC 61850-9-2LE process bus Sampled Values and IEC 61850-8-1 station bus applications. It implements mapping according to IEC 61850 edition 2 logical nodes and data models.

Use the TESLA 4000 to subscribe sampled values streams from merging units. Apply the Model 4000-SV to publish and subscribe to GOOSE messages from protective relays and switchgear. The Model 4000-SV also supports direct streaming of MMS reports to remote clients, eliminating the need for RTUs. The Model 4000-SV supports the top-down or bottom-up engineering process defined in the IEC 61850-6 standard. Such flexibility permits standardization and interoperability of fault and disturbance recording solutions as the industry moves towards fully digital substations.


  • Complete integrated insight of power system health
  • Performance monitoring of substation IEDs and equipment
  • Over 1000 user settable triggers capture vital information that could be missed by relays in the system
  • Information provided for wide area monitoring (WAMS) and analysis
  • As a PMU, streams up to 36 phasors, 24 analog quantities, and 64 digital statuses simultaneously

Specific Benefits of IEC 61850-Based Fault and Disturbance Recording System

  • Savings on costly wiring runs from instrument transformers (located in substation yards) to conventional DFRs located in substation control house
  • Practical elimination of CT saturation by eliminating copper cabling between CTs and DFRs
  • Absence of open CT secondary improves operational safety
  • Ease of commissioning, future modification, and expansion
  • Continuous self-monitoring capability using the IEC 61850 GOOSE repetition mechanism and IEC 61850 Edition 2 LGOS/LSVS logical nodes
  • Interoperability of DFR systems and protective relaying systems using common measurements available from merging units
