Model 1511-LTC

Model 1511-LTC

The INCON Model 1511-LTC Programmable Position Monitor provides accurate local and remote indication of load tap changer position.

Applications

  • Indicates tap position for load tap changers on transformers utilizing slidewire (resistive) transmitters
  • Provides flexible, real-time, outputs to interface with SCADA, PLCs, and computers
  • Provides visual and electrical indication of changes in tap position
  • Performs absolute position feedback by providing positive confirmation that the LTC has moved to the required tap position as directed
  • Programmable for uni-polar (0 to 32 taps) or bi-polar (-16 to +16 taps) applications

  • Capabilities

    The Model 1511-LTC indicates the position of transformer load tap changers and can be used to perform a number of functions to help improve system operation.

    • Analog output is unaffected by noisy or intermittent input signals
    • Accepts a 0-24 VDC signal from a slidewire (resistive) transmitter
    • Provides regulated 24 VDC slidewire power
    • Mathematically averages 1000 input signal samples to accurately determine the actual input signal value
    • Provides high and low draghand position indication
    • Offers programmable limit outputs for alarm and control (optional)

    Features

    • Interfaces LTC position information to SCADA systems
    • Extremely accurate signal conditioner
    • Analog and/or digital output
    • Large five-digit LED display
    • Hard-wired security/ lockout feature
    • Non-volatile storage of program parameters
    • Easy, menu-driven, set up mode through its front panel
