RET 521-C3 Transformer Protection Terminal by Robert Mihayo is a document available to read on EtoBox.
What is RET 521-C3 Transformer Protection Terminal about?
The document discusses a numerical transformer terminal called RET 521-C3 that provides protection and control for three-winding transformers. It features transformer differential protection, restricted earth fault protection on the low, medium and high voltage windings, and other protections like overvoltage, neutral overvoltage, and overexcitation. The RET 521-C3 has flexible settings, communication capabilities, and can be used for applications with up to three transformer windings and multiple circuit b
