D60 Line Distance Protection System
Chapter 2: Product description
Product descript ion
This chapter outlines the product, order codes, and specifications.
2.1 Product description
The D60 Line Distance Protection System is part of the Universal Relay (UR) series of products. It is a microprocessor-based
relay for use on transmission lines of any voltage level, without, with, and in the vicinity of series compensation, in three-
pole and single-pole tripping applications. The primary function of the relay consists of five phase and ground distance
zones of protection, either mho or quadrilateral as per user selection, with built-in logic for the five common pilot-aided
schemes. The distance elements are optimized to provide good measurement accuracy with fast operating time, even
when used with capacitive voltage transformers (CVTs), and can be supervised by detection of power swings. The relay
also provides directional ground overcurrent elements, which are commonly used as part of an overall line protection
system.
D60 phase distance zones can be configured to work with voltages and currents fed from VTs and CTs located
independently from one another on either side of a three-phase power transformer. The relay compensates accordingly to
preserve reach and correct target information regardless of the location and type of fault. This feature allows backup
protection applications for generators and power transformers.
A close-into-fault (or switch-on-to-fault) function is performed by the line pickup element. Out-of-step tripping, three-pole/
single-pole dual-breaker autoreclosing, synchrocheck, fault location, and many other functions are also available. In
addition, overcurrent and undervoltage protection, fault diagnostics, power metering, and remote terminal unit (RTU)
functions are provided. The D60 provides phase, neutral, and ground time overcurrent protection. The time overcurrent
functions can be programmed with multiple curve shapes or FlexCurve™ for optimum coordination.
Voltage, current, and power metering is built into the relay as a standard feature. Current parameters are available as total
waveform root mean square (RMS) magnitude, or as fundamental frequency only RMS magnitude and angle (phasor).
Diagnostic features include an event recorder capable of storing 1024 time-tagged events, oscillography capable of
storing up to 64 records with programmable trigger, content and sampling rate, and data logger acquisition of up to 16
channels, with programmable content and sampling rate. The internal clock used for time-tagging can be synchronized
with an IRIG-B signal, using the Simple Network Time Protocol (SNTP) over the Ethernet port, or using the Precision Time
Protocol (PTP). This precise time stamping allows the sequence of events to be determined throughout the system. Events
can also be programmed (via FlexLogic™ equations) to trigger oscillography data capture that can be set to record the
measured parameters before and after the event for viewing on a computer PC. These tools significantly reduce
troubleshooting time and simplify report generation in the event of a system fault.

Several options are available for communication. A faceplate RS232 port can be used to connect to a computer for the
programming of settings and the monitoring of actual values. The rear RS485 port allows independent access by operating
and engineering staff. It can be connected to system computers with baud rates up to 115.2 kbps. All serial ports use the
Modbus RTU protocol. The IEC 60870-5-103 protocol is supported on the RS485 interface. IEC 60870-5-103, DNP, and
Modbus cannot be enabled simultaneously on this interface. Also only one of the DNP, IEC 60870-5-103, and IEC 60870-5-
104 protocols can be enabled at any time on the relay. When the IEC 60870-5-103 protocol is chosen, the RS485 port has a
fixed even parity and the baud rate can be either 9.6 kbps or 19.2 kbps. The 100Base-FX or 100Base-TX Ethernet interface
provides fast, reliable communications in noisy environments. The Ethernet port supports IEC 61850, IEC 61850-90-5,
Modbus/TCP, TFTP, and PTP (according to IEEE Std. 1588-2008 or IEC 61588), and allows access to the relay via any
standard web browser (D60 web pages). The IEC 60870-5-104 protocol is supported on the Ethernet port. The Ethernet
port also supports the Parallel Redundancy Protocol (PRP) of IEC 62439-3 (clause 4, 2012) when purchased as an option.
Secure Routable GOOSE (R-GOOSE) is supported with software options.
Settings and actual values can be accessed from the front panel or EnerVista software.
The D60 uses flash memory technology that allows field upgrading as new features are added. Firmware and software are
upgradable.

• Password security — Basic security present by default
• EnerVista security — Role-based access to various EnerVista software screens and configuration elements. The
feature is present by default in the EnerVista software.
• CyberSentry security — Advanced security available using a software option. When purchased, the option is
automatically enabled, and the default Password security and EnerVista security are disabled.
2.2.0.1 EnerVista security
The EnerVista security management system is a role-based access control (RBAC) system that allows an administrator to
manage the privileges of multiple users. This allows for access control of UR devices by multiple personnel within a
substation and conforms to the principles of RBAC as defined in ANSI INCITS 359-2004. The EnerVista security
management system is disabled by default to allow the administrator direct access to the EnerVista software after
installation. It is recommended that security be enabled before placing the device in service.
Basic password or enhanced CyberSentry security applies, depending on purchase.
2.2.0.2 Password security
Password security is a basic security feature present by default.
Two levels of password security are provided: command and setting. Use of a password for each level controls whether
users can enter commands and/or change settings.
The D60 supports password entry from a local or remote connection. Local access is defined as any access to settings or
commands via the faceplate interface. This includes both keypad entry and the through the faceplate RS232 port. Remote
access is defined as any access to settings or commands via any rear communications port. This includes both Ethernet
and RS485 connections. Any changes to the local or remote passwords enables this functionality.
When entering a settings or command password via EnerVista or any serial interface, the user must enter the
corresponding connection password. If the connection is to the back of the D60, the remote password must be used. If the
connection is to the RS232 port of the faceplate, the local password applies.
Password access events are logged in the Event Recorder.
2.2.0.3 CyberSentry security
CyberSentry embedded security is available using a software option (Level 1) that provide advanced security services.
When the option is purchased, the basic password security is disabled automatically.
CyberSentry provides security through the following features:
• An Authentication, Authorization, Accounting (AAA) Remote Authentication Dial-In User Service (RADIUS) client that is
centrally managed, enables user attribution, provides accounting of all user activities, and uses secure standards-
based strong cryptography for authentication and credential protection
• A Role-Based Access Control (RBAC) system that provides a permission model that allows access to UR device
operations and configurations based on specific roles and individual user accounts configured on the AAA server (that
is, Administrator, Supervisor, Engineer, Operator, Observer roles)
• Security event reporting through the Syslog protocol for supporting Security Information Event Management (SIEM)
systems for centralized cybersecurity monitoring
• Strong encryption of all access and configuration network messages between the EnerVista software and UR devices
using the Secure Shell (SSH) protocol, the Advanced Encryption Standard (AES), and 128-bit keys in Galois Counter
Mode (GCM) as specified in the U.S. National Security Agency Suite B extension for SSH and approved by the National
Institute of Standards and Technology (NIST) FIPS-140-2 standards for cryptographic systems
CyberSentry user roles
CyberSentry user roles (Administrator, Engineer, Operator, Supervisor, Observer) limit the levels of access to various UR
device functions. This means that the EnerVista software allows for access to functionality based on the user’s logged in
role.

Example: Administrative functions can be segmented away from common operator functions, or engineering type access,
all of which are defined by separate roles (see figure) so that access of UR devices by multiple personnel within a
substation is allowed.
