Product Introduction
Transformer issues in substations require quick resolution. The ABB RET615E-E works as a dedicated protection, control, measurement, and supervision IED for two-winding power transformers, unit transformers, and generator-transformer blocks.
In field deployments of 615 series units, this model delivers stable differential protection with good inrush handling. It supports thermal overload and backup protection effectively. Bottom line — it performs when CT data matches the transformer nameplate. Honestly, the withdrawable format speeds up field replacements.
