DATA RECOVERY
The combined accuracy of the SEPCOS with its user-friendly touch screen interface (Display) removes the need of an oscilloscope or other extra measuring equipment.
• Display of the various screens through the service software S-web embedded in the control and protection unit SePcoS developed by Sécheron Sa.
• application of recovered data from the SePcoS during the short-circuit testing for validation and setting of protection functions.
