NATIONAL FOREWORD

This Indian Standard (Part 10) (Second Revision) which is identical with IEC 60050-(448) :1995‘international Electrotechnical Vocabulary — Chapter 448: Power system protection’ issued by theInternational Electrotechnical Commission (lEC) was adopted by the Bureau of Indian Standards on therecommendation of the Basic Electrotechnical Standards Sectional Committee and approval of theElectrotechnical Division Council.

This standard was first published in 1968. The first revision was published in 1993. The second revisionhas been undertaken in order to bring it in line with the latest IEC publication IEC 60050-(448) :1995.

The text of IEC Standard has been approved as suitable for publication as an Indian Standard without

deviations. Certain conventions are, however, not identical to those used in Indian Standards. Attentionis particularly drawn to the following:

a) Wherever the words ‘International Standard’ appear referring to this standard, they shouldbe read as ‘Indian Standard’.

b) Comma (,) has been used as a decimal marker while in Indian Standards, the currentpractice is to use a point (.) as the decimal marker.

For the purpose of deciding whether a particular requirement of this standard is complied with, thefinal value, observed or calculated expressing the result of a test or analysis, shall be rounded off inaccordance with IS 2:1960 ‘Rules for rounding off numerical values (revised)’. The number of significantplaces retained in the rounded off value should be the same as that of the specified value in thisstandard.

Protection, generally distance protection, using telecommunication, with undemeach protectionat each section end and in which a signal is txmsmitted when a fault is detected by the under-reach protection. Receipt of the signal at the other end permits a sequential measurement by anoverreach zone to initiate tripping.

Removal of the blocking signal together with thereceipt of the unblocking signal permits the initiation of tripping by the local protection.

Nore .- If no unblocking signal is received following removal of the blocking signal, it is usual-ly arranged to permit the overreach protection to initiate tripping within a variable time intervalusually in the range 1OO-2(K) ms.

is too low to allow operation of the main fatdtdetecting elements such that the remote signal isnot sent. Receipt of the signal at the weak infeed end, subject to appropriate locaf conditionsbeing fulfdled. results in reflex transmission of the received signal back to the strong irrfeed endto permit tripping at that section end.

automatic restoration equipment

Equipment intended to initiate the scheduled, sequential and delayed automatic reconnection ofcircuit-breakers or other specific switching dewces.

Nofe .- Automatic restoration could follow an unsuccessful automatic reclosure or a generalizeddisconnection condition with, or w~thout, automatic reclosing operation. Automatic restoration isnormally programmed to restore voltage partially. or to whole stations, after a widespread distur-bance has occurred.

Operation of zone 1 protection a: end C will initiate tripping at C and also send a signal to C).

On reception of the signal, tripping at D will be initiated only if there is a suitable local permissive critarion.

Permissive criterion can be given by:

starters (zone 3) of distance protection;

directional or non-directional underimpedance relay;

undervoltage relay;

overcurrent relay;

Reverselooking

Signal received from CE Block zone A

This scheme requires measuring relays looking in the reverse direction. If a reverse looking relay detects an

external fault it will send a signal to the opposite end and block zone A at that end.

In the case of internal fault zone A will operate in a similar way as a permissive overreach protection.

If a fault is detected by zone A in C, the blocking signal disappears ●nd ●n unblocking signal is received in D.Zone A-tripping will be unblocked and tripping will be initiated at D. Similar operation will occur in C after datac-tion operation of zone A in D.

If no unblocking signal is received after the blocking signal has disappeared, zone A-tripping will be unblockedfor a period of T1-T2. T1 -T2 is normally set at 100-200 ms.

NOTE - The blocking signal is sometimes referred to as a guard signal.

Zone A will not initiate tripping without a signal being received from the remote end.

Zone A at C detects a fault and sends a signal to D. On reception of the signal, the overreach zone A at D willinitiate tripping at D.

Similar operation will take place at C when a signal is sent from zone A at D’ to C

in a tull distance protection normally the measuring relays of the second zone will be used as sending and per-

missive criteria.

In a switched distance protection normally a separate measuring unit must be used as zone A.
