1.3 Features

This device is based on a 32-bit high performance dual-core processor, internal high speed
bus and intelligent I/O ports, and the hardware is in modularized design and can be
configured flexibly, featuring interchangeability and easy extension and maintenance.

Modularized hardware design makes this relay be easily upgraded or repaired by a qualified
service person. Various function optional modules can satisfy various situations according to
the different requirements of the users.

The adoption of 16-bit A/D converter and the dual-channel sampling technology can ensure
the accuracy and reliability of protection sampling and the correctness of protection operation.
It also provides dedicated current transformers for metering, and ensures the high accuracy of
telemetering with 48-point high speed sampling rate per cycle.

This device can sample the analog values from the traditional instrument transformers, or
receive the sampled values from the electronic transformers. It can support the protocol
IEC60044-8, IEC61850-9-2 and GOOSE.

Various algorithms for protection and measurement have been completed in this device for
the feature of electronic transformer sampling, such as the error prevention method of
multi-algorithms data anomaly for the digital channels, to realize high accuracy and reliability
under various conditions of network faults or communication interruption.

This device has powerful GOOSE functions, and the connection and cooperation between
some devices can be realized without using electrical cables, to facilitate the realization of
such functions as simple bus differential protection, overload interlock shedding function and
backup automatic transfer function etc.
