To be confirmed at the time of ordering.
Protection and control
UR series relays include the most complete and unique
The protection algorithms, these algorithms can provide unparalleled security
Completeness and system uptime. Feature list of UR series products
All of the relays in each type are listed (in the following section)
Protective element.
For different protection and control functions, UR series relays are available
Prepare different forms of I/O (Specific functions should be based on the specific model
It is determined). Equipped I/O includes:
CTs and VTs
UR series relays can be configured with up to 24 analog currents
CT and VT signals, these
The signal is used to monitor AC power lines. The series relay branch
Take a 1A and 5A CT. Special function modules available include:
A CT module with a sensitive ground input (the module can
Provides ground fault protection in high impedance ground systems) and a
A high impedance fault detection module (for use due to sagging wires)
To provide reliable detection of faults).
Monitoring and measurement
UR series relays include high accuracy for all AC signals
Measurement and recording function. Voltage, current, and power measurement

RMS amplitude and Angle (vector) of current parameters in UR system
Column relays are also measurable parameters. UR series relays also
Can be used as a replacement for a digital fault recorder (DFR)
Substitute to use.
The measured values include:
Synchronous phasor (Plan 2005)
Voltage phasor
Symmetrical component of voltage
Current phasor
Symmetric component of current

The measured signal can be displayed locally, can also be uploaded, and can be
Measurement signals can also be stored in a wave recording or data
Record in the file.
Diagnostic functions such as wave recording, event recording, data recording and so on
The combination of EnerVista software tools can greatly shorten failures
The exclusion time, and can be in the event of a system failure
Simplify the report generation process.
Wave recording
This series of relays can be equipped with up to 64 wave recording channels, which
These channels are used to monitor any physical I/O points or to monitor internally
The digital and analog variables. Waveform tracking and digital status functions
Ability to provide power systems as well as capture during specific trigger events
Visual display of operational data. The maximum sampling rate is every week
Wave 64 samples, up to 64 fault records can be stored in
UR series of relays.
Digital I/O
UR series relays are configured with 96 digital inputs (power system
The voltage rating can be up to 250V) and 64 digital inputs
Out. These inputs and outputs can be protected in substations or otherwise
Applications for monitoring and controlling a wide range of auxiliary devices.
Types of digital I/O modules include: tripping to determine the rating
The A type module, C type module and fast C type module, since
Hold modules and solid state modules, these modules or with DC
Voltage and current monitoring module, or without voltage and electricity
Flow monitoring module. Mechanical locking output can be interlocked with security
The application is used in combination so that mechanical switches can be replaced.
All digital I/O modules have a speed of less than 4ms
The I/O module supports both wet and dry contacts.
High current disconnect capability and fast trip and return capability
The power solid state output module is ideal for direct trip applications
Choice.
Transmitter I/O
The RTD and dcmA modules can be used to monitor system parameters, for example
For example, temperature, vibration, pressure, wind speed and flow rate. simulate
Inputs can be used from the controller to the SCADA system, to the programmable
Procedure logic controllers or to other user interface devices (e.g
For example, panel display) hardwire connection.
Remote I/O
Remote I/O features are available in one of UR series relays or others
Number of IEDs or controllers shared according to IEC 61850 standards
Means of word point status information. Remote output with other UR systems
Column devices for remote input can be passed in compliance with IEC61850 standards
The GSSE and GOOSE (or conform to earlier versions of the UR series)
The communication system is carried out using the UCA 2.0 standard protocol
Seamless connection. Security is recommended for distribution logic and I/O
Peer-to-peer communication to design more complex schemes.
Direct I/O
Direct I/O can be connected in a dedicated section of optical fiber (single mode
Or multimode) on UR relays, RS422, G.703, or
The C37.94 interface provides secure peer-to-peer communication. In this case
There is no need to connect any switchgear because the IED device can
Configure with direct ring connections or redundant (dual) ring connections.
This feature has been optimized for speed and can be used in distributed logic
For use in applications, this feature can also be used as an option
The number of single relay chassis inputs/outputs is expanded to be used.
