The MiCOM P63x series differential protection devices are designed for fast, selective, short-circuit protection of transformers, motors, generators and other installations.

Providing quick and selective differential protection, the MiCOM 63x is easily interfaced to almost any kind of substation control or SCADA system. It is user-friendly and provides clear readings from extensive recordings.

High-speed, three-system differential protection

MiCOM P63x provides high-speed three-system differential protection using a triple-slope characteristic and two high-set differential elements in combination with transformer inrush restraint, overfluxing restraint and through-stabilization.

By entering the nominal values of transformer windings and associated CTs, users obtain amplitude and vector group matching. The devices also incorporate many supplementary protective functions. MiCOM P63x provides four setting groups for easy adaptation to varying system operation conditions.

Systems versatility and easy, clear readings

Equipped with 1A/5A setting software, MiCOM P63x has two communication interfaces for SCADA and RTU, and numerous communication protocols. It allows easy and complete device settings and readings from extensive recordings. Available for flush or wall mounting, MiCOM P63x benefits from InterMiCOM interfacing for direct end-end communication between two protection devices.
