Preface
The relay type NV10P can be typically used in HV, MV and LV distribution systems, on transformers
or for electrical machines.
It can be used for system decoupling, load shedding and loss of main (islanding) protection.
In addition to the main protection element, the breaker failure (BF) , Trip Circuit Supervision (TCS) and
programmable logic (PLC) are also provided are also provided.
Input circuits for inductive VTs TV or direct connection
Following input circuits are available:
Three voltages (line-to-line) with nominal voltages programmable in the range 50...130 V (U
R
=100V)
or 200...520 V (U
R
= 400V) and one residual voltage input with nominal voltage programmable in the
range 50...130 V (U
ER
=100V).
Input circuits for electronic Sensor
Following input circuits are available:
Three voltages (line-to-ground) with 20/√3 kV nominal voltage); the residual voltage is calculated
from phase voltages.
Setting, programming and reading operations must be effected by means of Personal Computer with
ThySetter software or by means of remote communication interface (RS485 bus and Ethernet net-
work); all operations must be performed through MMI if enabled.
According to the hardware confi gurations, the NV10P protection relay can be shipped in various
case styles depending on the required mounting options:
Flush.
Projecting mounting.
Rack.
With separate operator panel.
Other options are:
Auxiliary power supply operating range.
Communication protocols.
