The RTD and mA inputs can also be used for

tracking the position of the on-load tap changer.

The four mA outputs can be used for transferring

freely selectable measured or calculated analog

values to devices provided with mA inputs.

Product highlights

• Extensive range of protection and control

functionality for two-winding HV/MV power

transformers, including advanced and fast

differential protection with high inrush stability

• Support for various neutral earthing options,

matching either high-impedance or numerical

low-impedance restricted earth-fault principles

• Automatic voltage regulation of power

transformers with a motor-driven on-load tap-changer
