8.5.3 Functionality
The tap changer position indication function TPOSYLTC is used for transformer tap
position supervision. The binary inputs can be used for converting a binary-coded
tap changer position to a tap position status indication. The RTD module, available
as an option, provides the RTD sensor information to be used and the versatile
analog inputs enabling the tap position supervision through mA.
