directional earth fault protection. Furthermore, the voltage
measurements enable several other protection functions like
voltage and frequency protection.
The modern technology in association with an extensive self-
supervision system and a reliable construction ensures an
extremely high availability for the VAMP feeder and motor
managers.

Main features
•
Fully digital signal handling with a powerful 16-bit
microprocessor, and high measuring accuracy on all the
setting ranges due to an accurate 16-bit A/D conversion
technique.
•
Wide setting ranges for the protection functions, e.g. the
earth fault protection can reach a sensitivity of 0.5%.
•
Integrated fault location for short-circuit faults.
•
The manager 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 manager to various substations
and alarm systems due to flexible signal-grouping matrix in
the manager.
•
Possibility to control six objects (e.g. circuit-breakers,
disconnectors).
•
Status of eight objects (e.g. circuit-breakers, disconnectors,
switches).
•
Freely configurable 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 a keypad and a local
HMI or by means of a PC based VAMPSET user interface.
•
All events and indications are in non-volatile memory.
•
Easy configuration, parameterisation and reading of
information via local HMI, or with a VAMPSET user
interface.
•
Easy connection to power plant automation system due to a
versatile serial connection and several available
communication protocols.
•
Built-in, self-regulating ac/dc converter for auxiliary power
supply from any source within the range from 40 to 265 V
dc or ac. The alternative power supply is for 18 to 36 V dc.
•
Built-in disturbance recorder for evaluating all the
analogue and digital signals.
