1. Introduction
1.1. About this manual
This manual provides thorough information on the protection relay REF 610 and its
applications, focusing on giving a technical description of the relay.
Refer to the Operator’s Manual for instructions on how to use the
Human-Machine Interface (HMI) of the relay, also known as the Man-Machine
Interface (MMI), and to the Installation Manual for installation of the relay.
1.2. The use of the relay
The feeder protection relay REF 610 is a versatile multifunction protection relay
mainly designed to protect incoming and outgoing feeders in a wide range of feeder
applications.
REF 610 is based on a microprocessor environment. A self-supervision system
continuously monitors the operation of the relay.
The HMI includes a Liquid Crystal Display (LCD) which makes the local use of the
relay safe and easy.
Local control of the relay via serial communication can be carried out with a
computer connected to the front communication port. Remote control can be carried
out via the rear connector connected to the control and monitoring system through
the serial communication bus.

2. Safety information
Dangerous voltages can occur on the connectors, even though the
auxiliary voltage has been disconnected.
National and local electrical safety regulations must always be
followed.
The device contains components which are sensitive to electrostatic
discharge. Unnecessary touching of electronic components must
therefore be avoided.
The frame of the device has to be carefully earthed.
Only a competent electrician is allowed to carry out the electrical
installation.
Non-observance can result in death, personal injury or substantial
property damage.
Breaking the sealing tape on the upper handle of the device will result
in loss of warranty and proper operation will no longer be guaranteed.
When the plug-in unit has been detached from the case, do not touch
the inside of the case. The relay case internals may contain high voltage
potential and touching these may cause personal injury.

3. Instructions
3.1. Application
REF 610 is a versatile multifunction protection relay mainly designed for protection
of incoming and outgoing feeders in MV distribution substations. REF 610 can also
be used as back-up protection for motors, transformers and generators, in industrial
as well as in utility applications.
The large number of integrated protection functions, including three-stage
overcurrent protection, two-stage, non-directional earth-fault protection as well as
thermal protection, makes REF 610 a complete protection against overcurrent and
earth faults.
The optional arc protection for detection of arc situations in air insulated metal-clad
switchgears and the auto-reclose function for automatic clearing of overhead line
faults increase the range of applications further.
The large number of digital inputs and output contacts allows a wide range of
applications.
3.2. Requirements
To secure correct and safe operation of the relay, preventive maintenance is
recommended to be performed every five years when REF 610 is operating under
the specified conditions; see below and section Technical data.
When being used for real-time clock or recorded data functions, the battery should
be changed every five years.
Environmental conditions
3.3. Configuration
Setting and connection examples
The appropriate configuration of the output contact matrix enables the use of the
signals from the protection stages as contact functions. The start signals can be used
for blocking co-operating protection relays and signalling.
Fig. 3.3.-1 and Fig. 3.3.-2 represent REF 610 with the default configuration: all trip
signals are routed to trip the circuit breaker. In Fig. 3.3.-1, the residual current is
measured via a core-balance current transformer and the output contacts are
connected to enable the use of the auto-reclose function. In Fig. 3.3.-2, the residual
current is measured via a summation connection of the phase current transformers
and the output contacts are connected to enable the use of the trip lockout function.
