Description
The protection relay DIGISAVE RN is used to protect isolated or compensated neutral point lines and transformers in medium voltage networks and also possesses the full functionality of a motor protection.
DIGISAVE RN possesses a number of functions and features that enable it to respond appropriately to the requirements of our customers' systems. For example, the fact that connections can be made using a plug-in socket, plus the comprehensive power management of the protection relay's power feed (power consumption <1VA). In this version the current converter power feed requires only a principal current converter with a power rating of 1VA. This dual-power or triple-power relay can operate with a converter power supply as low as 0,2In at 200mVA per phase.
Freely parameterisable LEDs and a four-line screen displaying intelligible messages make it possible to clearly and easily convey the status values of the various processes, enabling operators to always be alert to the equipment's current and foregoing states. Protection parameters are set up in the simplest possible way - on the protection relay itself, using a single turn-and-press knob and with menu guidance. Naturally you can also use the operating program DIGICOM to set up the parameters.
DIGISAVE RN meets the high standard expected of "swiss made quality" and fulfils all the homologation tests specified in IEC60255.
