1. Application GUID-EB939A4F-1C88-4EB1-A217-571FEF72AC7B v2
The RET650 provides fast and selective protection,
monitoring and control functions for two- and three-
winding transformers, autotransformers, generator-
transformer units and shunt reactors. The IED is
designed to operate correctly over a wide frequency
range in order to accommodate power system frequency
variations during disturbances and generator startup
and shutdown. Apparatus control for 3 circuit breakers
is included.
A fast differential protection function with built-in
transformer ratio matching and vector group
compensation makes this IED the ideal solution even for
the most demanding applications. Since RET650 has
very low requirements on the main CTs, no interposing
CTs are required. The differential protection function is
provided with 2nd harmonic and waveform-blocking
restraint features to avoid tripping for magnetizing
inrush current, and 5th harmonic restraint to avoid
tripping for overexcitation.
The differential function offers a high sensitivity for
low-level internal faults. The unique and innovative
sensitive differential protection feature of the RET650
provides the best possible coverage for internal turn-to-
turn winding faults, based on the theory of symmetrical
components.
A low impedance restricted earth-fault protection
function is available as a complimentary sensitive and
fast main protection against winding earth faults. This
function includes a directional zero-sequence current
criterion for additional security.
Tripping from pressure relief/Buchholz and temperature
devices can be implemented through the IED's binary
inputs, where trip signal conditioning can be performed
(pulsing, lockout, additional logics, etc). The binary
inputs are thoroughly stabilized against disturbances in
order to prevent incorrect operations due to for
example DC system capacitive discharges or DC earth
faults.
Versatile phase, earth and zero sequence overcurrent
functions with directional capability provide further
alternative backup protections. Thermal overload with
two time-constants and breaker failure protection is
also available.
A built-in disturbance and event recorder provides
valuable data to the user about status and operation for
post-fault disturbance analysis.
One pre-configured package has been defined for the
following application:
• Three-winding transformer in single breaker
arrangements (A05)
The package is configured and ready for direct use.
Analog and control circuits have been predefined and
other signals need to be applied as required for each
application. The pre-configured IED can be changed and
adapted to suit specific applications with the graphical
configuration tool.
Forcing of binary inputs and outputs is a convenient way
to test wiring in substations as well as testing
configuration logic in the IEDs. Basically it means that all
binary inputs and outputs on the IED I/O modules (BOM,
BIM and IOM) can be forced to arbitrary values.
Central Account Management is an authentication
infrastructure that offers a secure solution for enforcing
access control to IEDs and other systems within a
substation. This incorporates management of user
accounts, roles and certificates and the distribution of
such, a procedure completely transparent to the user.
The Flexible Product Naming allows the customer to use
an IED-vendor independent 61850 model of the IED. This
customer model will be used as the IEC 61850 data
model, but all other aspects of the IED will remain
unchanged (e.g., names on the local HMI and names in
the tools). This offers significant flexibility to adapt the
IED to the customers system and standard solution

3. Differential protection
Transformer differential protection T3WPDIF M16104-3 v17
The Transformer differential protection is provided with
internal CT ratio matching, vector group compensation
and settable zero sequence current elimination.
The function can be provided with up to six three-phase
sets of current inputs if enough HW is available. All
current inputs are provided with percentage bias
restraint features, making the IED suitable for two- or
three-winding transformer in multi-breaker station
arrangements.

differential protection
The setting facilities cover the application of the
differential protection to all types of power
transformers and auto-transformers without load tap
changer as well as shunt reactors and local feeders
within the station. An adaptive stabilizing feature is
included for heavy through-fault currents.
Stabilization is included for inrush and overexcitation
currents respectively, cross-blocking is also available.
Adaptive stabilization is also included for system
recovery inrush and CT saturation during external faults.
A high set unrestrained differential current protection
element is included for a very high speed tripping at
high internal fault currents.
Included is an sensitive differential protection element
based on the theory of negative sequence current
component. This element offers the best possible
coverage of power transformer windings turn to turn
faults.
Restricted earth-fault protection, low impedance
REFPDIF M13047-3 v18
Restricted earth-fault protection, low-impedance
function REFPDIF can be used on all directly or low-
impedance earthed windings. The REFPDIF function
provides high sensitivity and high speed tripping as it
protects each winding separately and thus does not
need inrush stabilization.
The REFPDIF function is a percentage biased function
with an additional zero sequence current directional
comparison criterion. This gives excellent sensitivity and
stability during through faults.
4.
Current protection
Instantaneous phase overcurrent protection PHPIOC
M12910-3 v12
The instantaneous three phase overcurrent function has
a low transient overreach and short tripping time to
allow use as a high set short-circuit protection function.
Four-step phase overcurrent protection OC4PTOC
M12846-3 v16
The four step three-phase overcurrent protection
function OC4PTOC has an inverse or definite time delay
independent for step 1 to 4 separately.
All IEC and ANSI inverse time characteristics are
available together with an optional user defined time
characteristic.
The directional function needs voltage as it is voltage
polarized with memory. The function can be set to be
directional or non-directional independently for each of
the steps.
A second harmonic blocking level can be set for the
function and can be used to block each step individually.
Instantaneous residual overcurrent protection
EFPIOC M12701-3 v15
The Instantaneous residual overcurrent protection
EFPIOC has a low transient overreach and short tripping
times to allow use for instantaneous earth-fault
protection, with the reach limited to less than typical
eighty percent of the transformer impedance at
minimum source impedance. EFPIOC can be configured
to measure the residual current from the three-phase
current inputs or the current from a separate current
input.
Four step residual overcurrent protection, zero
sequence and negative sequence direction EF4PTOC
M13667-3 v18
The four step residual overcurrent protection EF4PTOC
has an inverse or definite time delay independent for
each step.
All IEC and ANSI time-delayed characteristics are
available together with an optional user defined
characteristic.
EF4PTOC can be set directional or non-directional
independently for each of the steps.
IDir, UPol and IPol can be independently selected to be
either zero sequence or negative sequence.
Second harmonic blocking can be set individually for
each step.
Residual current can be calculated by summing the three
phase currents or taking the input from neutral CT

Thermal overload protection, two time constant
TRPTTR M13243-3 v10
If a power transformer reaches very high temperatures
the equipment might be damaged. The insulation within
the transformer will experience forced ageing. As a
consequence of this the risk of internal phase-to-phase
or phase-to-earth faults will increase.
The thermal overload protection estimates the internal
heat content of the transformer (temperature)
continuously. This estimation is made by using a
thermal model of the transformer with two time
constants, which is based on current measurement.
Two warning levels are available. This enables actions in
the power system to be done before dangerous
temperatures are reached. If the temperature continues
to increase to the trip value, the protection initiates a
trip of the protected transformer.
The estimated time to trip before operation is
presented.
Breaker failure protection CCRBRF M11550-6 v16
Breaker failure protection (CCRBRF) ensures a fast
backup tripping of the surrounding breakers in case the
own breaker fails to open. CCRBRF can be current-
based, contact-based or an adaptive combination of
these two conditions.
A current check with extremely short reset time is used
as check criterion to achieve high security against
inadvertent operation.
Contact check criteria can be used where the fault
current through the breaker is small.
CCRBRF can be single- or three-phase initiated to allow
use with single phase tripping applications. For the
three-phase version of CCRBRF the current criteria can
be set to operate only if two out of four for example,
two phases or one phase plus the residual current start.
This gives a higher security to the back-up trip
command.
CCRBRF function can be programmed to give a single- or
three-phase re-trip of its own breaker to avoid
unnecessary tripping of surrounding breakers at an
incorrect initiation due to mistakes during testing.
5. Multipurpose protection
General current and voltage protection CVGAPC M13083-3 v6
The protection module is recommended as a general
backup protection with many possible application areas
due to its flexible measuring and setting facilities.
The built-in overcurrent protection feature has two
settable current levels. Both of them can be used either
with definite time or inverse time characteristic. The
overcurrent protection steps can be made directional
with selectable voltage polarizing quantity. Additionally
they can be voltage and/or current controlled/
restrained. 2nd harmonic restraining facility is available
as well. At too low polarizing voltage the overcurrent
feature can be either blocked, made non directional or
ordered to use voltage memory in accordance with a
parameter setting.
Additionally two overvoltage and two undervoltage
steps, either with definite time or inverse time
characteristic, are available within each function.
The general function suits applications with
underimpedance and voltage controlled overcurrent
solutions. The general function can also be utilized for
generator transformer protection applications where
positive, negative or zero sequence components of
current and voltage quantities are typically required.
6. Secondary system supervision
Fuse failure supervision FUFSPVC SEMOD113820-4 v11
The aim of the fuse failure supervision function
FUFSPVC is to block voltage measuring functions at
failures in the secondary circuits between the voltage
transformer and the IED in order to avoid inadvertent
operations that otherwise might occur.
The fuse failure supervision function basically has three
different detection methods, negative sequence and
zero sequence based detection and an additional delta
voltage and delta current detection.
The negative sequence detection algorithm is
recommended for IEDs used in isolated or high-
impedance earthed networks. It is based on the
negative-sequence quantities.
The zero sequence detection is recommended for IEDs
used in directly or low impedance earthed networks. It is
based on the zero sequence measuring quantities.
The selection of different operation modes is possible
by a setting parameter in order to take into account the
particular earthing of the network.
A criterion based on delta current and delta voltage
measurements can be added to the fuse failure
supervision function in order to detect a three phase
fuse failure, which in practice is more associated with
voltage transformer switching during station
operations.

7. Control
Switch controller SCSWI M13486-3 v7
The Switch controller (SCSWI) initializes and supervises
all functions to properly select and operate switching
primary apparatuses. The Switch controller may handle
and operate on one three-phase device or up to three
one-phase devices.
Circuit breaker SXCBR M13489-3 v6
The purpose of Circuit breaker (SXCBR) is to provide the
actual status of positions and to perform the control
operations, that is, pass all the commands to primary
apparatuses in the form of circuit breakers via binary
output boards and to supervise the switching operation
and position.
Circuit switch SXSWI M16492-3 v6
The purpose of Circuit switch (SXSWI) function is to
provide the actual status of positions and to perform
the control operations, that is, pass all the commands to
primary apparatuses in the form of disconnectors or
earthing switches via binary output boards and to
