Ordering Information

Budgetary Price:
$4,730

The SEL-RTS Relay Test System is designed for testing protective relays having low-level test capabilities. The system consists of the SEL-AMS Adaptive Multichannel Source and either the SEL-5401 or SELTEST™ software.

  • Economical, Quiet, Compact Adaptive Multichannel Source (AMS) Provides 12 Analog Outputs with 16 bit Resolution

    Test relays and other devices by simulating the waveforms from current or potential transformers, as presented to the internal analog input section of the devices under test. Using low-level analog signals reduces the cost, weight, power consumption, cooling and noise of test equipment that supplies high-level voltages and currents.

  • Digital I/O to Simulate Equipment and Monitor Test

    The AMS includes six digital inputs to sense relay outputs and change test states. Use ten contact outputs to simulate station equipment, communications assisted protection points, and more.

  • State-Simulation Software For Flexible Testing

    The included SEL-5401 Test System Software provides a virtual front panel, plus multiple states to simulate power system changes and faults:

    • Sinusoidal outputs simulate steady-state conditions and changed-states.
    • Amplitude ramping supports relay element threshold tests
    • Frequency ramping simulates system events and tests frequency elements
    • COMTRADE files or Mathcad® replayed through analog outputs.
    • Digital inputs can change state to simulate equipment or system event
    • Digital outputs programmed for each state simulate communications and equipment contacts

     

  • Complete Test Package

    The AMS includes 24/48/125 and 250 vdc power supply , to power the equipment under test and the contact I/O. Cable harnesses for the equipment under test are included

  • Test two complete line terminals. Use the Adaptive Multichannel Source to provide the 3 voltage and 3 current waveforms to the relays for each end of a transmission line. Monitor the relay actions with the contact inputs, and simulate breaker 52A contacts with the contact outputs.

     

  • Test that your relay settings cause the relay to operate properly for a known condition. Set the relay, then play-back event reports of known fault conditions to determine if the relay operates correctly.

     

  • Use amplitude ramping to test relay element thresholds.

     

  • Provide instantaneous and event report data, and simulate breaker operations in an informative demonstration for training, education, or other presentations.

Application Example Connections

  • Serial link from the PC to the SEL-4000 Adaptive Multichannel Source.
  • Test signals to each relay include:
      • Three voltages to simulate line VTs
      • Three currents to simulate line CTs
      • Five contacts to simulate 52A and communications equipment
  • Test signals from each relay include three contacts to simulate trip and communications equipement.
  • Serial link from each relay to the PC to collect event reports.
  • Block diagram for a two-terminal line test

    • Order input power option of 110 vac or 220 vac.
