FOR FURTHER ASSISTANCE CHAPTER 1: INTRODUCTION
1
Only qualified personnel are to operate the device. Such personnel must be thoroughly familiar with all safety
cautions and warnings in this manual and with applicable country, regional, utility, and plant safety regulations.
Hazardous voltages can exist in the power supply and at the device connection to current transformers, voltage
transformers, control, and test circuit terminals. Make sure all sources of such voltages are isolated prior to
attempting work on the device.
Hazardous voltages can exist when opening the secondary circuits of live current transformers. Make sure that
current transformer secondary circuits are shorted out before making or removing any connection to the current
transformer (CT) input terminals of the device.
For tests with secondary test equipment, ensure that no other sources of voltages or currents are connected to such
equipment and that trip and close commands to the circuit breakers or other switching apparatus are isolated,
unless this is required by the test procedure and is specified by appropriate utility/plant procedure.
When the device is used to control primary equipment, such as circuit breakers, isolators, and other switching
apparatus, all control circuits from the device to the primary equipment must be isolated while personnel are
working on or around this primary equipment to prevent any inadvertent command from this device.
Use an external disconnect to isolate the mains voltage supply.

Chapter 2: Product description
Product descript ion
This chapter outlines the product, order codes, and specifications.
2.1 Product description
The L60 Line Phase Comparison System is part of the Universal Relay (UR) series of products. It provides a simple phase-
comparison principle successfully employed by analog and static relays for many years, along with the significant
advantages of a modern microprocessor-based relay. The phase comparison element performs the following calculations:
• Samples and filters three-phase AC currents at a rate of 64 samples per cycle
• Computes sequence components of the current
• If two CT/VT modules are employed for breaker-and-a-half applications, the relay sums up two currents and performs
the breaker-and-the-half logic calculations
• Forms a composite signal from current components according to a user-defined setting
• Forms local positive and negative squares from the composite signal sent to remote terminal and used locally along
with the channel delay value
• Samples received from remote terminal squares 64 samples per cycle measuring magnitude of the pulse voltage
• Processes received samples to compensate for asymmetry and distortions in the signal
• Detects fault condition with the fault detector
• Compares coincidence of local and remote squares which indicate the presence of internal or external faults
• Detects transient conditions to block the phase comparison function
All processed signals, including transmitted and received pulses, are available in oscillography for commissioning,
maintenance, and analysis. The L60 integrates received pulses on a sample-per-sample basis, similar to the analog phase-
comparison principle, making the relay exceptionally robust on noisy channels. All permissive and blocking schemes, as
well as single and dual phase comparison, are incorporated into a single protection element and can be selected with a
relay setting. The L60 supports two and three-terminal applications, can be used for single- and three-pole tripping
applications, and supports breaker-and-a-half applications. Multiple backup functions include three-zone phase and
ground distance, directional overcurrent, pilot schemes, and current and voltage elements.
Control features include synchrocheck, autoreclosure, and control for two breakers. Monitoring features include CT failure
detector, VT fuse failure detector, breaker arcing current, disturbance detector and continuous monitor.
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. 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 to
program settings and monitor 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, Modbus/TCP, TFTP, and PTP
(according to IEEE Std. 1588-2008 or IEC 61588), and it allows access to the relay via any standard web browser (UR 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.
Settings and actual values can be accessed from the front panel or EnerVista software.
The figures show typical two-terminal and three-terminal applications.

2.2 Security
The following security features are available:
• 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 as a software option. When purchased, the options are
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 L60 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 L60, 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 a software option that provides advanced security services. When this 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
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. Permissions for each role are outlined in the next section.
Figure 2-3: CyberSentry user roles
The following types of authentication are supported by CyberSentry to access the UR device:
• Device Authentication (local UR device authenticates)
• Server Authentication (RADIUS server authenticates)
The EnerVista software allows access to functionality that is determined by the user role, which comes either from the local
UR device or the RADIUS server.
The EnerVista software has a device authentication option on the login screen for accessing the UR device. When the
"Device" button is selected, the UR uses its local authentication database and not the RADIUS server to authenticate the
user. In this case, it uses its built-in roles (Administrator, Engineer, Supervisor, Observer, Operator) as login names and the
associated passwords are stored on the UR device. As such, when using the local accounts, access is not user-attributable.
In cases where user-attributable access is required especially to facilitate auditable processes for compliance reasons, use
RADIUS authentication only.
When the "Server" Authentication Type option is selected, the UR uses the RADIUS server and not its local authentication
database to authenticate the user.

No password or security information is displayed in plain text by the EnerVista software or UR device, nor is such
information ever transmitted without cryptographic protection.
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: Observer cannot write any settings.

CyberSentry server authentication
The UR has been designed to direct automatically the authentication requests based on user names. In this respect, local
account names on the UR are considered as reserved and not used on a RADIUS server.
The UR detects automatically whether an authentication request is to be handled remotely or locally. As there are five local
accounts possible on the UR, if the user ID credential does not match one of the five local accounts, the UR forwards
automatically the request to a RADIUS server when one is provided.

If a RADIUS server is provided, but is unreachable over the network, server authentication requests are denied. In this
situation, use local UR accounts to gain access to the UR system.
2.3 Order codes
The order code is on the product label and indicates the product options applicable.
The L60 is available as a 19-inch rack horizontal mount or reduced-size (¾) vertical unit and consists of the following
modules: power supply, CPU, CT/VT, contact input and output, transducer input and output, and inter-relay
communications. Module options are specified at the time of ordering.
The L60 is specified with two CT/VT modules (8F and 8P). When the L60 is applied in two-breaker configurations (such as
breaker-and-a-half or ring configurations), the currents from the two CTs are summed internally within the relay or
externally. If the voltage is not supplies to the relay, some functions (such as distance, undervoltage, and synchrocheck)
are not available.
Order codes are subject to change without notice. See the ordering page at
