Introduction
This part of the manual describes the protection functions,
provides a few application examples and contains technical
data. This part of the manual also includes the operating
instructions.
Mounting and Commissioning Instructions are provided in a
separate mounting and commissioning manual
(VMMC.EN0xx).
1.1.
Application
The versatile basic protection functions, the wide variety of
additional functions and several available communication
protocols render the overcurrent and earthfault relay VAMP
140 an ideal protection relay for power plants and substations
as well as for industry, marine and off-shore applications.
The modern technology in association with an extensive self-
supervision system and a reliable construction ensures an
extremely high availability for the VAMP 140 protection relay.
The relay is used for overcurrent and earthfault feeder
protection. The relay can also be used in other applications
where a single-, two- or three-phase protection relay is needed.

Main features
•
Fully digital signal handling with a powerful 16 bit micro
processor and high measuring accuracy on all setting
ranges due to an accurate 12 bit A/D conversion technique.
•
Easy enabling and disabling of protection functions
according to the needs of the intended application.
•
Wide setting ranges for the protection functions.
•
Flexible external control and blocking possibilities due to
the digital signal control input (DI).
•
Easy adaptation of the relay to various substations and
alarm systems due to a flexible signal-grouping matrix in
the relay.
•
Recording of events and fault values into an event register,
from which data can be read via the key pad and the display
or by means of the PC based VAMPSET user interface.
•
Signals from the relay’s current measurement transducer
can be wired to an external meter or a SCADA system.
