EACH AND EVERY PIECE OF EQUIPMENT IS TESTED IN THEFACTORY BEFORE DESPATCHING TO THE SITE. PRECOMMISSIONING TESTING AT SITE IS DONE TO PROVE THAT

1. TO ENSURE THAT EQUIPMENT WAS NOT SUBJECTED TO ANY

DAMAGE DURING TRANSPORTATION.

2. EACH EQUIPMENT HAS BEEN INSTALLED CORRECTLY.

3.EACH EQUIPMENT IS WORKING IN CO-ORDINATION WITH OTHEREQUIPMENTS AS DESIRED.

. ALL THE PROTECTION AND CONTROL SCHEMES ARE WORKING IN

ACCORDANCE WITH RELEVENT SPECIFICATION AND PROTECTIONREQUIREMENTS.

!. EACH EQUIPMENT HAS BEEN ADJUSTED PROPERLY IN ACCORDANCE

WITH SETTINGS.

NEED FOR TESTS ONELECTRICAL INSTALLATION


3/51

". THE INSTALLATION IS SAFE FOR PUTTING IN TO SERVICE.

#. THE PREIODICAL TESTING WILL ENSURE THEAVAILABILITY OF THE EQUIPMENT FOR THE RELIABILITY OF THE SYSTEM PERFORMANCE.

$. THE TESTING OF PROTECTIVE SYSTEM FOR COMBINATIONOF CONTINGENCIES THAT CAUSE THE SYSTEM INSTABILITY ANDSEPARATION WILL EVOLVE THE DYNAMICS OF THE SYSTEM.

%. THIS WILL ALSO HELP IN UPDATING THE SYSTEM

DISASTER CONTROL MEASURES IMPLEMENTED.

1&. FINALLY THIS WILL GIVE A RECOGNITION FOR THE

POSSIBILITY TO FACE THE UNFORSEEN MULTIPLECONTINGENCIES AND'OR NATURAL CALAMITY WHICH MAYCAUSE THE COLLAPSE OF THE ENTIRE SYSTEM
