Schneider Easergy P3T32 Relay has a modular design, and it can be optimized to medium and big sized transformers.

Schneider Easergy P3T32 Relay Main characteristic and options

• The relay is a transformer protection relay for medium sized transformers in power distribution.

• 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

Schneider Easergy P3T32 Relay Protection functions

• Universal, adaptive protection functions for user-configurable transformer applications
