RMU Protection

RMU Protection

The ADR141S is member of ADITYA series designed to meet demand of Ring Main Unit (RMU) type switchgear where Auxiliary supply as well as PT voltage is not available. The relay takes power from CT’s and continuously monitors all 3 phases and earth current, through CT connections. The high-speed microcontroller samples this current through a 12 bit A/D converter. The micro controller performs powerful Digital Algorithms to find out Amplitude of fundamental current signal, and then these values are use for protection and metering function.
