Safety recommendations

The warming contained in this document are all-important for safety; special attention must be paid

to the following symbols:

Installation and commissioning must be carried out by qualiﬁed person; Thytronic assumes no re-

sponsibility for damages caused from improper use that does not comply all warning and caution in

this manual.

In particular the following requirements must be met:

• Remove power before opening it.

• Verify the voltage absence by means suitable instrumentation on relay connections; attention must

be paid to all circuits supplied by external sources (binary input, CT, etc...)

• Care must be taken when handling metal parts.

Insulation tests

After insulation tests, hazardous voltages (capacitor charges,...) may be arise; it is advisable to grad-

ually reduce the test voltage avoiding to erase it abruptly.

DANGER Death, severe personal injury or substantial property damage will result if proper precautions

are not taken

WARNING Death, severe personal injury or substantial property damage can result if proper precautions

are not taken.

CAUTION

Settings must be established on the basis of a coordination study.

Numerical values inside examples have educational purpose only; they don’t be used, in no way,

for actual applications.

CAUTION Minor personal injury or property damage can result if proper precautions are not taken

Start Leave an initial condition or reset condition (Pickup)

Trip Operation (with operate time)

Operating time Duration of time interval between the instant when the character-

istic quantity in reset condition is changed, under speciﬁed condi-

tions, and the instant when the relay operates

Dropout ratio The ratio of a reset value to an operate value in well-speciﬁed con-

ditions. The dropout ratio may be lower or greater than 1 according

as an over or under element is considered

Reset time Duration of the time interval between the instant when the charac-

teristic quantity in operate condition is changed, under speciﬁed

conditions, and the instant when the relay operates.

The stated reset time is related to a step variation of characteristic

quantity in operate condition to the reset condition.

Overshoot time The critical impulse time for a relay which is in its reset condition,

is the longest duration a speciﬁed change in the input energizing

quantity(ies) (characteristic quantity), which will cause the relay

to change to operate condition, can be applied without the relay

switches. The overshoot time is the difference from the operate time

and the critical impulse time.

The declared values for the overshoot time are applicable with the

lower setting value of the operation time.

Preface

The relay can be typically used as differential protection fo generators, motors and short lines.

The phase and amplitude adaptation of the current for differential protection can be achieved both

through internal compensation is through the use of external adapters transformers

Following input circuits are available:

• Three phase current side H

• Three phase current side L

• One residual current.

For any input the rated current is independently selectable at 1 A or 5 A using dip-switch.

In addition to the main protection element, the breaker failure (BF), CT monitoring (74CT), Trip Circuit

Supervision (TCS) and programmable logic (PLC) are also provided.

Setting, programming and reading operations must be effected by means of Personal Computer with

ThyVisor software or by means of remote communication interface (RS485 bus, Ethernet network

and USB); all operations must be performed through MMI.

According to the hardware conﬁgurations, the NT10 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.
