Introduction
This part of the user manual describes the protection functions,
provides application examples and contains technical data of
the functions.
The numerical device includes basic voltage and frequency
protection functions needed in common applications. Further,
the device includes several programmable functions, such as
trip circuit supervision and check of synchronism and also
communication protocols for various protection and
communication applications.
1.1.
Main features
Fully digital signal handling with microprocessor
technology, and high measuring accuracy on all the setting
ranges due to an accurate A/D conversion technique.
Set of functions for voltage and frequency based protection
of lines, generators and transformers
The device can be matched to the requirements of the
application by disabling the functions that are not needed.
Flexible control and blocking possibilities due to digital
signal control inputs (DI) and outputs (DO).
Easy adaptability of the device to various substations and
alarm systems due to flexible signal-grouping matrix in the
device.
Possibility to control objects (e.g. circuit-breakers,
disconnectors) from relay HMI or SCADA/automation
system
Freely configurable large display with six measurement
values.
Freely configurable interlocking schemes with basic logic
functions.
Recording of events and fault values into an event register
from which the data can be read via relay HMI or by means
of a PC based VAMPSET user interface.
All events, indications, parameters and waveforms are in
non-volatile memory.
Easy configuration, parameterisation and reading of
information via local HMI, or with a VAMPSET user
interface.
Easy connection to various automation systems due to
several available communication protocols. Native
IEC61850 implementation is available as option.
