1. Introduction
VAMP 220 is a state-of-the-art arc protection system for
electrical power distribution systems. By using VAMP 220 in
switchgears considerable safety improvements are obtained in
the form of minimized injury and damage in case of an arc
fault.
VAMP 220 uses modern microprocessor technology and
provides numerous new features previously not found in
similar devices.
Key features of VAMP 220:
a total operating time of 7 milliseconds
exact location of the activating arc sensor
self-supervision of the entire system
system wiring using standard copper cables
self configuration.
In addition to the high-level requirements set for protective
relays, VAMP 220 meets the most recent EMC-standards.
Figure 1-1 VAMP 220 arc protection system.
VAMP 220 is a modular system composed of a master unit,
slave units, arc sensors, temperature sensors, and possible trip
multiplying units and interface units.
The master unit VAMP 220 includes all the main functions of
the arc protection system, such as overcurrent, arc and
temperature supervision. Up to 10 slave units can be connected
to a master unit.
The slave unit VAM 12 CD serve as a link between the sensors
and the master unit. Each slave unit can be connected to ten
fixed arc sensors, one temperature sensor and one portable arc
sensor.

VAMP Ltd Arc protection system
User manual VAMP 220 / 220R
VM220.EN004 Vamp 24h support phone : [phone]
The arc sensor VA 1 DA is activated by strong light which it
transforms to a current signal. The signal is tranferred via the
slave to the master unit.
The portable sensor VA 1 DP is an arc sensor that can be
temporarily connected to a slave. Attached to persons it
improves the personal safety during work in live switchgears.
The master unit provides up to four trip output channels for
tripping circuit-breakers. By connecting the trip multiplying
relay VAR 4 CE to the outputs, up to 16 trip outputs can be
obtained.
The standard sensor cable length is 6m. Arc sensors can be con-
nected over longer distances, up to 20 m, using a sensor with a
shielded cable.
Thanks to the modularity, the system can be flexibly adapted to
a variety of arc protection applications, ranging from simple
systems with one master unit and one slave unit to complex
solutions comprising multiple master units, for instance, in
applications with selective arc protection.
VAMP220 suits both low voltage and medium voltage
switchgears. It can be installed in new as well as existing
switchgears.

When the conditions for an arc short circuit occur
(simultaneous overcurrent and arc signal), the master unit
trips the circuit-breaker(s) of the incoming feeder(s). A master
unit can trip up to four circuit breakers. If more than four
parallel trip outputs are required, the trip multiplier relay VAR
4 CE can be used.

User manual VAMP 220 / 220R
VM220.EN004 Vamp 24h support phone : [phone]
The tripping of the arc protection system can be backed up by
employing the built-in circuit breaker failure protection
subunit. This unit trips another breaker, for instance, the
upstream circuit breaker, in case the main circuit breaker
should fail to operate. Thus, it gives the system redundancy
and increased security.
The master unit includes a unidirectional arc input, a
unidirectional current dependent arc output, and a bi-
directional arc in/output. Furthermore, the master unit is
equipped with a unidirectional overcurrent output and a bi-
directional overcurrent in/output. With these properties a
selective arc protection can be built even in complex
distribution systems.
Any voltage within the range 40 - 265 V ac or dc (or optionally
18 - 36 V dc) can be used as auxiliary supply voltage for the
master unit. All internal supply voltages required by the
system are derived from the auxiliary supply voltage of the
master unit.
NOTE!
It is recommended that the auxiliary voltage is fed from a
secured source, which is unaffected by a possible arc fault.
2.1.2. Functional description
The current inputs of the three-phase overcurrent subunit
(220) or two-phase overcurrent and E/F subunits (220R) are
connected in series with any other possible protective devices of
the switchgear. The start value of the overcurrent (220) /
overcurrent + E/F (220R) subunits are set according to the
preconditions determined by the arc short circuit and/or E/F
current (220R) , independently of the settings of any other
protection systems within the switchgear. The start value is set
with a potentiometer knob on the control panel of the master
unit (220). VAMP 220R has a separate E/F setting.
The arc protection unit obtains its measuring signals from the
slave units, to which the arc sensors of the system are
connected. The unit starts when one or more of the system's
arc sensors are activated.
At a simultaneous activation of the overcurrent unit (220) /
overcurrent or/and E/F unit (220R) and the arc protection unit,
the arc protection system operates and the output elements trip
the circuit-breakers.
NOTE!
No operation takes place if only one unit (either the
overcurrent or arc protection unit) is activated.

VAMP 220 / 220R Arc protection system
User manual VAMP Ltd
10 Vamp 24h support phone : [phone] VM220.EN004
NOTE!
The arc, overcurrent and E/F (220R) stages can also be
activated from external BI/O signals.
The circuit breaker failure protection subunit (CBFP) starts if
the preconditions for the operation of the arc protection unit
have not disappeared when a set operate time (80, 100 or 150
ms) has elapsed since the arc fault trip. The CBFP, which is
optional, trips its own circuit breaker. When not used, its trip
contacts are left unwired.
If not used for circuit breaker failure protection, the CBFP
output contact (TRIP3) can be set to operate in parallel with
the actual trip circuit (TRIP1), if two circuit breakers are to be
tripped simultaneously.
The desired function for the third trip circuit (TRIP3) is to be
specified when ordering the master unit.
By default, TRIP3 is programmed for CBFP function with a
time delay of 80 ms.
Figure 2.1.2-1 shows the TRIP signalling block diagram of
VAMP 220.

2.2. Slave unit VAM 12 CD
The slave units, which can be mounted into suitable places in
the switchgear compartments, serve as links between the
sensors and the master unit. Each slave unit can be connected
to ten arc sensors and one portable arc sensor. Up to 10 slave
units can be connected to one master unit. The master unit and
the slave units are interconnected by means of modular cables.
The slave units contain, for instance, the self-supervision of the
connected arc sensors.

Figure 2.2-1 Slave unit VAM 12 CD.
When the system operates due to an arc fault, information of
the sensor that caused the operation is forwarded by the slave
unit to the master unit. The slave number and sensor number
is then displayed by the master unit.
The slave unit supervises all its sensors continuously. In an
internal fault situation the fault information is transferred to
the master unit and the fault can be viewed on the display of
the master unit.
A fault alarm is also given if an arc sensor connected to the
slave unit remains in active state for more than 7 s. This can
happen, for instance, if the arc sensor is exposed to direct sun
light. At the same time the corresponding slave unit is
disconnected from the master unit in order to prevent false
circuit-breaker trippings. When the interference light
disappears, the function of the slave unit is restored.
2.3. Arc sensor VA 1 DA
The arc sensor is a light sensitive element, which is activated
by strong light. Arc sensors should be mounted in the
switchgear cubicles in such a way that they cover the space to
be protected as completely as possible.

VAMP Ltd Arc protection system
User manual VAMP 220 / 220R
VM220.EN004 Vamp 24h support phone : [phone]
Figure 2.3-1 Arc sensor VA 1 DA.
A sudden increase of the light intensity is interpreted as an arc
fault. The electronic circuits of the sensor transforms the light
message into a current message and transmits it to the slave
unit, which forwards it to the master unit.
The sensitivity of the sensor is nearly equal over the front side.
At the rear side the sensitivity decreases remarkably. See
Figure 2.3-2. In a switchgear, however, the light caused by an
arc is reflected from the walls. Therefore, the mounting position
of the sensor is not critical.
The standard sensor cable length is 6 m. As an option, a
shielded cable can be used for distances up to 20 m.

2.4. Portable sensor VA 1 DP
This module is a portable sensor element which can be
temporarily connected to the slave units. It is used to improve
personal safety during work, for instance during maintenance
work, in a live switchgear. The sensor should be located close to
the place where work is done. It can, for instance, be attached
to the breast pocket of the service man's shirt or boiler suit.
The function of the portable arc sensor equals that of the fix-
mounted arc sensors. The difference is that the portable arc
sensor can be moved around within the reach of the connection
cable.

Figure 2.4-1 Portable sensor VA 1 DP in use.
The connector of the portable arc sensor can be plugged into the
SENSOR connector of any slave unit of the arc protection
system. The portable sensor should be attached in such a way
that the sight is clear towards the working place.
NOTE!
To avoid false activations, the portable arc sensor must be dis-
connected from the slave unit immediately after use.
2.5. Trip multiplier relay VAR 4 CE
With the VAR 4 CE multiplying relay the TRIP signals can be
multiplied. Each multiplying relay has four ultra fast trip
outputs, each of which can trip its own circuit breaker. Any
combination of NO and NC contacts is available (to be specified
in the order, see Figure 5.6-1 and table 9.3-1).
Figure 2.5-1 Trip multiplier relay VAR 4 CE.

VAMP Ltd Arc protection system
User manual VAMP 220 / 220R
VM220.EN004 Vamp 24h support phone : [phone]
Up to four trip functions are available by connecting TRIP1
and/or TRIP2 output to the control inputs of the trip multiplier
relay. Auxiliary supply voltage is available from the 24 V OUT
terminals of the master unit.
2.6. Systems with multiple master units
Especially in medium-voltage switchgears the power may be
fed from two or more infeeders. At an arc fault situation, each
infeeder that can supply short circuit power must be tripped. In
these applications, the arc protection system may include
several master units, that is, one master unit per infeeder.
In applications with multiple master units, the master units
are interconnected via the BI/O connectors. When an arc sensor
in the system is activated, information is transferred over the
BI/O lines to all master units in the system. As a consequense,
all master units with the overcurrent subunit activated will
trip their respective circuit breakers.
If a master unit connected to the BI/O lines is tripping, and the
arc or overcurrent activation comes from a BI/O connection, the
identifier of the activated BI/O line will be shown on the
display.
2.7. Selective arc protection
The master unit facilitates a selective arc protection even in
more complex electricity distribution systems. As mentioned
earlier, it includes the following input/output modules:
•unidirectional arc input
•unidirectional arc output (current dependent)
•bidirectional arc in/output
•unidirectional overcurrent output
•bidirectional overcurrent in/output.
By utilizing these features, complex busbar systems can be
divided into separate zones. Each zone includes the parts of the
distribution system that are limited by two or more circuit-
breakers. See the example in Figure 2.7-1. Selective arc
protection means that all zones are protected independently of
each other.
In the example in Figure 2.7-1, VAMP 220 master units are
used for tripping the circuit-breakers K4, K5, K6 and K7 as
well as the actual infeeding circuit-breakers K1, K2 and K3.

VAMP 220 / 220R Arc protection system
User manual VAMP Ltd
16 Vamp 24h support phone : [phone] VM220.EN004
Suppose that an arc fault occurs in switchgear B in Figure 2.7-
1, in a situation where circuit-breaker K3 is closed and the
other two infeeding circuit-breakers are open. The arc fault
power is fed via K3 to switchgear C and further to switchgear B
by bus ducts E, A and D. The master unit of the bus duct D
(which trips the circuit-breaker K6) obtains the unidirectional
arc information from the B I/ O bus of the master unit in
switchgear B. In other words, when an arc occurs in switchgear
B, the arc information is forwarded to all master units that
limits that particular zone, independently on their physical
location. In the described infeeding arrangements the pre-
conditions for an arc fault (arc signal and overcurrent) are
fulfilled only in the master unit tripping the circuit-breaker K6.
Therefore, K6 is the only circuit breaker that is tripped.
In this example, the overcurrent BI/O lines are not used.
