RET650 - Transformer protection

For reliable protection and control of all types of power transformers and reactors

RET650 offer optimum ‘off-the-shelf’, ready-made solution for protection of two- and three-winding transformers. The type tested variant of RET650 IEDs (Intelligent Electronic Device) is delivered equipped and configured with complete functionality and with default parameters for easy handling of products – from ordering, engineering and commissioning to reliable operation.

The 650 series IEDs (Intelligent Electronic Device) has a number of useful features, such as a significantly reduced number of parameter settings and extended IED HMI functionality, including 15 dynamic three-color indication LEDs per page, on up to three pages, and configurable push-button shortcuts for different actions.
