Schneider Easergy P3G30 and P3G32 Generator protection with differential protection
Description
The Schneider P3G32 Numerical Relay has a modular design, and it can be optimized to medium and big-sized generators.
Main characteristic and options
• The relay is a generator-block transformer protection relay for medium sized generators in power generation. 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 Of Schneider P3G32 Numerical Relay
• Universal, adaptive protection functions for user-configurable generator and block transformer protection applications
• Neutral voltage displacement, overvoltage and frequency protection including synchrocheck for two breakers 2 Product introduction Generator protection with machine differential protection P3G/en M/J006 19
• 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
