T35 GE Multilin - Transformer Protection System

Brand: GE Multilin™

Model: T35 Transformer Protection System

Product Type: Transformer Protection System

Performance and Features: The T35 is a high-speed transformer differential protection system that provides advanced features in a cost-effective package. It includes improved security for transformer energization and inrush through a superior adaptive 2nd harmonic restraint algorithm. The system offers application flexibility for transformers with up to 6 sets of CTs, independent magnitude/phase angle compensation, and grounding settings.
