Tap Position Indicator for Power Transformers
The Tap Position Indicator is an essential device used in transformer control systems to continuously monitor and display the exact tap position of On Load Tap Changers (OLTC) and Off Circuit Tap Changers (DETC). It helps operators maintain proper voltage regulation and ensures safe and efficient transformer operation.
Designed for industrial and utility applications, our Tap Position Indicators are suitable for power transformers installed in substations, power generation plants, switchyards, and heavy industrial facilities.
The system receives position feedback from the OLTC mechanism through resistor chains, potentiometers, or encoder-based arrangements and converts it into a clear tap position display. The indicator can be supplied in analog, digital LED, or microcontroller-based versions depending on customer requirements.
