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: for
example overvoltage, undervoltage and residual voltage
supervision by measuring the phase voltages, over and
undervoltage supervision by measuring the line voltages,
overvoltage, undervoltage and residual voltage supervision
by measuring two line voltages and residual voltages (The
third line voltage is calculated).
•
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 voltage measurement transducer
can be wired to an external meter or a SCADA system.
•
Handy configuration, parameterization and reading of
information via the user panel or by means of the PC based
VAMPSET user interface.
•
Easy to connect to power plant automation systems due to
versatile serial connection and several available
communication protocols.
•
Latest events and indications are in non-volatile memory
•
Reliable built-in self-regulating dc/dc converter for auxiliary
power supply within the supply voltage range 40 - 265 V
dc/ac, optionally 24 V dc.
•
Built-in disturbance recorder for evaluating primary and
secondary, as well as neutral currents of the protected
object.
