Transformer protection RET650
Product version: 1.1
Authority check ATHCHCK
To safeguard the interests of our customers,
both the IED and the tools that are accessing
the IED are protected, by means of
authorization handling. The authorization
handling of the IED and the PCM600 is
implemented at both access points to the IED:
• local, through the local HMI
• remote, through the communication ports

IEC 61850-8-1 communication
protocol
The IED supports the communication
protocols IEC 61850-8-1 and DNP3 over TCP/
IP. All operational information and controls
are available through these protocols.
However, some communication functionality,
for example, horizontal communication
(GOOSE) between the IEDs, is only enabled
by the IEC 61850-8-1 communication protocol.
The IED is equipped with an optical Ethernet
rear port for the substation communication
standard IEC 61850-8-1. IEC 61850-8-1
protocol allows intelligent electrical devices
(IEDs) from different vendors to exchange
information and simplifies system
engineering. Peer-to-peer communication
according to GOOSE is part of the standard.
Disturbance files uploading is provided.
Disturbance files are accessed using the IEC
61850-8-1 protocol. Disturbance files are
available to any Ethernet based application
via FTP in the standard Comtrade format.
Further, the IED can send and receive binary
values, double point values and measured
values (for example from MMXU functions),
together with their quality, using the IEC
61850-8-1 GOOSE profile. The IED meets the
GOOSE performance requirements for

tripping applications in substations, as
defined by the IEC 61850 standard. The IED
interoperates with other IEC 61850-compliant
IEDs, tools, and systems and simultaneously
reports events to five different clients on the
IEC 61850 station bus.
The event system has a rate limiter to reduce
CPU load. The event channel has a quota of
10 events/second. If the quota is exceeded
the event channel transmission is blocked
until the event changes is below the quota,
no event is lost.
All communication connectors, except for the
front port connector, are placed on integrated
communication modules. The IED is
connected to Ethernet-based communication
systems via the fibre-optic multimode LC
connector (100BASE-FX).
The IED supports SNTP and IRIG-B time
synchronization methods with a time-
stamping resolution of 1 ms.
• Ethernet based: SNTP and DNP3
• With time synchronization wiring: IRIG-B
The IED supports IEC 60870-5-103 time
synchronization methods with a time
stamping resolution of 5 ms.
