NVA100X-D - Manual - 02 - 2016

For every of the four thresholds the following block criteria are available:

Logical block (Block1)

If the

I-I/U>BLK1

e/o

I-I/U>>BLK1

enabling parameters are set to

and a binary input is de-

signed for logical block (Block1), the concerning element is blocked off whenever the given input is
active.

[1]

The enabling parameters are available inside the

Set \ Proﬁ le A(or B) \ Voltage controlled-

restraint overcurrent 51V \

I-I/U> Element

(

I-I/U>> Element) \ Setpoints

menus, while the

Block1

function must be assigned to the selected binary input inside the

Set \ Board1(2) inputs \ Binary input

IN1-1...INx-x)

menus.

Selective block (Block2)

All along the protective elements the selective block may be set.
The logic selectivity function may be performed by means any combination of the following I/O:

One committed pilot wire input (BLIN1).
One or more binary inputs designed for input selective block.
One committed pilot wire output (BLOUT1).
One or more output relays designed for output selective block.

Only when the committed pilot wire are used the continuity check of the pilot wire link is active.
Use of committed pilot wire input BLIN1:

The protection is blocked off according the selectivity block criteria when the input BLIN1 is active.
The information about phase or phase+earth block may be select programming the

ModeBLIN1

parameter inside the

Set \ Proﬁ le A(or B) \ Selective block-BLOCK2 \ Selective block IN

menus.

Use of binary inputs:

If the

I-I/U>BLK2IN

and/or

I-I/U>>BLK2IN

parameters are set to

and a binary input is

designed for selective block (Block2), the protection is blocked off by phase elements (Block2 Iph)
or by any protection element (Block2 Iph/IE) according the selectivity block criteria.

menus.

Use of committed pilot wire output BLOUT1:

The information about phase or phase+earth block may be select programming the

ModeBLOUT1

parameter (

OFF - ON IPh - ON IPh/IE - ON IE

) inside

Set \ Proﬁ le A(or B) \ Selective block-

menus.

Use of output relay:

If the

I-I/U>BLK2OUT

and/or

I-I/U>>BLK2OUT

enable parameters are set to

and a out-

put relay is designed for selective block (Block2), the protection issues a block output by phase ele-
ments (BLK2OUT-Iph) or by any protection element (BLK2OUT-Iph/IE), whenever the given element
(Start) becomes active. The enable

I-I/U>BLK2OUT

and/or

I-I/U>>BLK2OUT

parameters
