Motor Management

The Agile P24xM Motor Management Series, a member of the field proven P40 Agile protective relay platform, and has been designed for the protection, control, and management of medium voltage motors in industrial applications. The P24xM series offers a small, flexible form factor, advanced and redundant communications, multiple I/O options, and is available with current inputs (P24NM) or with current and voltage inputs (P24DM). The P24xM series delivers reliable protection for pumps, conveyors, fans, and compressors to ensure maximum process uptime.

​

Protection & Control

Motor Protection & Control

The P24xM Series (P24NM, P24DM) deliver field proven protection, measurement and control algorithms built from GE’s P40 Agile range of protective devices.

The P24NM and P24DM devices offer multi-stage independent protection elements including a variety of curves in four setting groups. Machine thermal imaging monitoring, start supervision, and circuit breaker condition monitoring ensure maximum process uptime and system reliability.

Communications

Communications

The P24xM Series offers flexible and redundant communications options, simplifying device integration into SCADA or DCS systems.

Two communication ports are standard - a rear port providing remote communications and a front port for local operators. The front USB port allows the programming of settings, configuration of the programmable scheme logic, extraction and viewing of event, disturbance and fault records, viewing of measurements and the instigation of control functions.

 

The P24xM series supports the following advanced communication protocols:

• Courier / K-Bus

• Modbus

• IEC 60870-5-103

• DNP 3.0 (RS485 serial or Ethernet)

• IEC 61850 (100 Mbit/s Ethernet)

​

IEC 61850 or DNP 3.0 over Ethernet are available when the optional Ethernet port is ordered in the 30TE and 40TE models. Redundant Ethernet protocol PRP, HSR and RSTP are also available in dual RJ45 or dual fiber. The copper physical link option uses RJ45 connectors, the fiber option uses LC connectors. IEC 61850 offers high-speed data exchange, peer-to-peer communication, reporting, disturbance record extraction and time synchronization. To help smooth transition from the existing protocol to the IEC 61850 protocol, the P40 Agile relay had been designed to provide concurrent Courier, Modbus or DNP3 on the RS485 while provide IEC 61850 over Ethernet port.

Software

The Agile Generator/DG Interconnection/DLR P341-6 IEDs are now available with software 38/72. This software allows new enhancements and protection improvements in P341-6 range of products.

 

The IEDs available with the new software are:

• P341 Interconnection/DLR: Hardware P (P341) / Software v38 (standard), v72 (with DLR)

• P342-6 Generator: Hardware P (P342), M (P343/4/5/6) / Software v38

 

The new software features:

• Enhanced power protection with 4 stages of single phase power/VAR (P341-6) selectable as A/B/C phase or 4 stages wattmetric power/VAR (P345) and 4 stages of 3 phase power/VAR protection (P341-6)

• New minimum power setting reduced to 0.2%Pn for large generator reverse power applications

• New user curves for overcurrent, voltage dependent overcurrent, earth fault, SEF, under/overvoltage, NVD, V/Hz for creation of user specific characteristics eg for undervoltage fault ride through applications

• Independent voltage dependent overcurrent (51V) and underimpedance (21) protection

• New field failure directional line and increase in setting ranges for field failure elements

• 3rd stage of undervoltage protection

• Enhanced cybersecurity

• New PSL counters and timers settable in PSL or in settings enables more complex logic schemes to be created such as equivalent logic to TP2xx pole slipping (de-synchronization) relay

• A large range of communications protocols including IEC61850 8-1 and new DNP 3.0 over Ethernet

• New XCPU3 with extended memory, new opto input and PSU design (P and M hardware)
