1 Briefly Introduction
1.1 Application Scope
The PRS-7367 is a numerical distributed protection intended for protecting and monitoring various
primary apparatus including overhead line, underground cable, transformer, capacitor, etc.
PRS-7367 can be used in various voltage level, generally ranging from 10kV to 35kV. PRS-7367
can detect and clear all types of internal phase-to-phase.
PRS-7367 provides fast and selective protection, monitoring and control for feeders and
capacitors. The relay can operate correctly over a wide frequency range in order to accommodate
power system frequency variations during disturbances.
This relay can sample the analog values from the traditional instrument transformers, or receive
the sampled values from the electronic current and voltage transformers (via a merging unit). The
binary inputs and outputs of this relay can be configured according to the demands of a practical
engineering through the PRS IED Studio configuration tool auxiliary software, which can meet
some special requirements of protection and control functions.
This relay can fully support the IEC61850 communication protocol and GOOSE function, and can
completely meet the demands of a modern digitalized substation.
