Easergy™ MiCOM P532 - Line Differential Protection and Bay Control Device

Easergy MiCOM P532 provides a two-ended line differential protection function with all of the necessary protection communication interfaces.

Easergy MiCOM P532 is an inexpensive line differential protection device that features optional control functions for rapid and selective short-circuit and overload protection of cables and power lines. 

It provides a rapid three-stage differential protection system using a tripping characteristic with multiple knee points amongst the numerous supplementary functions. The optional control functions enable Easergy MiCOM P532 to control up to six switchgear units fitted to a bay panel, and to monitor their contact positions.

Easergy MiCOM P54x - Line Differential Protection Relays

Easergy MiCOM P54x is designed for high performance overhead line and cable applications, it interfaces readily with the longitudinal (end to end) communications channels and has optional distance backup protection.

Models available:

  • MiCOM P541, P542, P543, P544, P545, P546


Easergy MiCOM P541-P546 series provides high-speed current differential unit protection. The P54x is designed for all overhead line and cable applications, as it interfaces readily with the longitudinal (end to end) communications channel between line terminals.

A full range of back-up protection is integrated. This enhances the dependability of the protection, as hot-standby elements (such as distance zones and overcurrent) can be brought into service whenever a signaling channel outage may occur.
