Schneider Easergy P3L30 line differential and distance protection with Feeder protection relay
Description
The relay has a modular design and it can be optimized to almost all types of feeder protection applications in low and medium-voltage distribution systems.
Main characteristic and options
• The relay has all the necessary feeder protection for industrial and utility applications for power distribution networks. Synchrocheck and auto-reclosing extend automatic network control.
• The relay has an optional interface for connecting four arc flash point sensors.
• The relay has optional arc flash communications and high speed outputs to allow for simple arc flash system configuration.
• Two alternative display options
◦ 128 x 128 LCD matrix
◦ 128 x 128 LCD matrix detachable
• Power quality measurements and disturbance recorder enable capture of
transients
• Wide range of communication protocols, for example:
◦ Modbus TCP/IP
◦ Profibus
◦ IEC61850
The following options depend on the order code:
• power supply options
• earth fault overcurrent input sensitivity
• number of digital inputs
• number of trip contacts
• integrated arc-options (point sensors)
• various possibilities with communication interfaces:
◦ high-speed outputs
◦ simple arc flash system communications (BIO)
◦ fiber loop
• front panel protection of IP54

Protection functions
• Universal, adaptive protection functions for user-configurable applications like
feeder, motor, and voltage protection from basic non-directional to directional
overcurrent protection, thermal overload, and auto-recloser
• Neutral voltage displacement, overvoltage and frequency protection including
synchrocheck for two breakers
• Single-line diagram, measurements and alarms in the user-machine interface
(UMI)
• User-configurable interlocking for primary object control
• Optional arc flash detection utilizing point sensors and a fiber loop that can
provide system wide arc flash detection.
Virtual injection
• Current and voltage injection by manipulating the database of the product by setting tool disturbance recorder file playback through the product’s database
Robust hardware
• User-selectable Ethernet, RS485 or RS232 -based communication interfaces
• Designed for demanding industrial conditions with conformal-coated printed circuit boards
• Standard USB connection (type B) for Easergy P3 setting software
Common technology for cost efficiency
• Powerful CPU supporting IEC 61850
• Thanks to four setting groups, adaptation to various protection schemes is
convenient
User-machine interface (UMI)
• Clear LCD display for alarms and events
• Single-line diagram mimic with control, indication and live measurements
• Programmable function keys and LEDs
• Circuit breaker ON/OFF control
• Common firmware platform with other Easergy P3 range protection relays
