Quadrilateral Characteristic Advantages

Zone reach setting (Z) and Resistive reach (R) setting areindependent

Allows resistive reach to be set exactly according to thefault arc coverage required

No need to rely on characteristic expansion - you get whatyou set!


es s ve reac se ng ac s as e oa n er

Makes characteristic applicable to lines of all lengths,

without risking load encroachment trips

Characteristic simplicity - easy to test and commission

Resistive reach is constant throughout the length of thezone

MiCOM Distance Summary



14/17

P441/P442 Summary

Versatile distance relay for all HV EHV applications

Extremely secure - Delta techniques, for fault detection, directionality

and phase selection

Patented algorithms used in 3 generations of numerical relays

Overhead line and/or cable applications

Efficient use of panel space - size 40TE (P441) or 60TE (P442)


Universal distance protection - with a proven installed base

Menu-driven software for setting and analysis

Intuitive setting

Common Px40 training modules

Comprehensive back up protection

P442


15/17

P437 Summary

Distance protection for application up to and including the highestsystem voltages

Design experience - 3rd generation of numerical distance protectionfrom the same design team

Proven V> and shaped Z< starting for high sensitivity Z< starter acts as a load blinder, to ensure stability when no tripping is

wanted

Maintains and manages the stability of the grid


Out of step tripping to control system separation

An ideal complement to P44x family relays in dual-main distanceprotection applications

Advanced protection and control in a Modular platform

P437


16/17

P443 MiCOMho Summary

Mho and quadrilateral elements available within one device - line/cabletype and length not needed at time of ordering

Load blinder avoids spurious or cascade tripping, withoutdesensitising the protection

Selectable mho characteristic polarising permits control overexpansion - allowing support for compensated and non-compensatedapplications

The relay self-sets zone reaches from protected line data - simplesettin mode


Superimposed (I) fault and power swing detection requires nostarters to be set

Easy to set and apply

High Speed Distance Protection Designedfor Ease of Application
