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.

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.
