FUNCTION CHARACTERISTICS

CT supervision - 74CT

Preface

The CT monitoring function is employed to issue an alarm when secondary phase CTs and/or phase

input of the NC20 relay failure are detected.
Interruptions are detected by means of a symmetry criterion of the

input currents.

The symmetry factor is calculated comparing the minimum and maximum of the fundamental compo-

nents of the three phase currents (

LMIN

LMAX

Operation and settings

The starting of the timer occurs if both the following conditions are ﬁ lled:

(

LMIN

LMAX

) < S

that is the symmetry factor is lower than the S

adjustable threshold;

LMAX

> I*

Where
I*:

maximum phase current threshold

S<: element

pickup

value

S<:

operate time

If both conditions are ﬁ lled over the

adjustable time an alarm is issued.

The output may be assigned to the selected

S<TR-K

output relays inside the

Set\CT supervision-

74CT

submenu; the same for addressing the LED indicators

S<TR-L

If the

S<-BLK1

parameter is set to

, and a binary input is designed for logical block (Block1), the

CT supervision function is blocked off whenever the given input is active. The trip timer is held in re-
set condition, so the operate time counting starts when the input block goes down.

[1]

The

S<-BLK1

parameter is available inside the

Set\CT supervision-74CT

submenu.

All the parameters are common for A and B Proﬁ les.

Note 1 The exhaustive treatment of the logic block (Block 1) function may be found in the “Logic Block” paragraph inside
