Applications
Applications
- The INCON Model 1511-LTC is ideal for use in applications that require accurate position measurement.
- 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
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 programmable segmented position indication
- Offers programmable limit outputs for alarm and control (optional)
Features
