GE P40 Agile Series Intelligent Electronic Devices (IEDs)

GE P40 Agile Series Intelligent Electronic Devices (IEDs)

Product overview

The GE P40 Agile series includes intelligent electronic devices (IEDs) such as P14N (non directional feeders), P14D (directional feeders), and P94V (voltage and frequency), designed to provide comprehensive protection, control, and monitoring functions for power systems. This series of products integrates the design rigor and technology of transmission applications, suitable for new construction and renovation projects in public utilities and industrial markets. It can be applied to scenarios such as overhead lines, underground cables, busbars, circuit breakers, transformers, reactors, and distributed generation, supporting various applications from distribution (as primary protection) to transmission voltage levels (as backup protection), and is suitable for direct grounding, resistance grounding, and arc suppression coil systems.

Core functions

Protection and control

It has comprehensive current, voltage, power, and frequency protection functions, including multi-stage independent protection components, multiple curves (4 setting groups), high impedance faults, load intrusion, switch closure to faults, and fault locators.

Support functions such as rate of change, automatic reclosing for all schemes, TEFD, and synchronization check.

Measurement and Monitoring

Provide comprehensive metering and power on diagnostic functions, including two-level circuit breaker faults and circuit breaker status monitoring.

Support switch device monitoring, including CT/VT, DC power supply, complete trip circuit monitoring, circuit breaker faults, switch control and status (up to 8), as well as up to 2048 events and 10.5 second disturbance records.

Advanced communication

Up to two Ethernet ports, optional redundancy protocol (RSTP or PRP/HSR).

Supports SNTP or IRIG-B time synchronization, multiple communication protocols including IEC 61850, Modbus, DNP 3.0, IEC 60870-5-103, and Courier/K-Bus, and supports simultaneous operation of IEC 61850 and DNP3 Ethernet protocols.

Ease of Use

Compact and withdrawable design, available in 4-inch, 6-inch, and 8-inch size options.

Through programmable binary input voltage, universal CT, and simplified standardization of power supply, seamless migration with K-series relays is achieved, facilitating on-site relay upgrades.
