100-series protection relay
The VAMP protection relays include all the main properties you have been
used to see in the medium voltage distribution protection systems.
Additionally the relays include a number of other innovative and unique
features. The following basic functions are the same in all relays.
Basic features
Comprehensive and versatile setting
and programming possibilities.
Programmable blocking and output
matrix.
Disturbance recorder and evaluation
software
Several communication protocols are
available in the relays.
Continuous self-supervision.
Robust metal enclosure.
Wide auxiliary supply voltage range.
Two mechanical sizes: 100-serie and
200-serie.
Unique features
All VAMP overcurrent relays can be
equipped with arc sensors. The
sensors are installed, for instance, inthe cable compartment of the
outgoing feeders.
Thanks to optional integrated
transducers, any measured and
calculated values can freely beconnected to the mA outputs.
Maximum demand measurementquantities and disturbance recorder
are available for load profiling and
fault evaluation.
User Interface
Settings, parameters and metered values
are accessible from the front panel. Thesame values are also available via the PC-
connection on the front panel of the relays.
The Windows compatible, free of charge,VAMPSET software package can be used
with all VAMP protection relays and the
power monitoring unit (VAMP 260).

Interface in the VAMP 200 series relays.
Selective arc protection
Features
Communication protocols, VAMPSET setting, configuration and
disturbance evaluation software
VAMP protection relays and the power monitoring unit can be connected to
an automation system utilizing of the various communication protocols used
in industrial and utility applications. IEC 60 870-5-103, SPA bus, MODBUS RTU,
Modbus/TCP and Profibus DP protocols are supported.
ABB’s SPA bus communication protocol
is widely used at powerdistribution substations in utility andindustrial applications.
Profibus DP protocol is widely used for theprocess control as well as for the power
distribution monitoring and control in theprocess industry.
VAMP protection relays can be connectedto the Ethernet network via the Modbus/TCP protocol.
VAMPSET software is compatible with Windows XP /
2000 / NT / 98 / 95 operating system.
Configuration and on-line
monitoring of the VAMP
protection relays and powermonitoring units can either be
done via display or using the
VAMPSET software. The samesoftware supports evaluation of
disturbance recorder files from
the VAMP protection relays. Theprogram is free and can be
downloaded from our home
page at
