Transformer protection and control RET630

RET630 has been designed to protect power and step-up transformers

in utility and industrial power distribution systems. RET630 is also ideal for

transformer bay control.

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
