MiCOM Agile P441, P442 & P444 distance protection relays

Product Description

MiCOM Agile P441, P442 & P444

Distance Protection Relays

Part of the MiCOM P40 platform, the Agile P441, P442 andP444 numerical full scheme distance relays provide flexible, fast and reliableprotection of transmission and sub-transmission lines. They include full scheme6-zone distance, plus aided directional earth fault (DEF) and comprehensivebackup protection for utility lines and cables at all voltage levels,particularly oriented towards transmission grids.

These distance protection systems are ideal for single circuit breaker application, single and/or 3-pole tripping, and includes a fullsuite of monitoring, control and recording capabilities plus fault locator, autore close and check synchronism.

Key features:

• Dual algorithm distance operation for maximum fault detection dependability
• Deploy in traditional CT/VT applications, or digital substation architectures with merging units and non-conventional instrument transformers using IEC 61850-9-2 process bus
• Distance to fault location assists dispatching of maintenance crews 
• Full-scheme relay offers fast, discriminative response to double-circuit, cross-country and evolving faults
