Preparation of completion Reports
After completing the electrical installation works of a new HV/EHV installation or making additions to an existing HV/EHV installation, the electrical contractor who carried out the installation works shall conduct the necessary pre-commission checks and tests and prepare the completion report in the prescribed format. The completion report shall be signed by the electrical contractor and the owner of the installation and submitted to the Electrical Inspectorate and the supply authority. A model form ofthe completion report is given at the end of this chapter.
The completion report shall necessarily contain the following details
1. Full name plate details of all electrical machines and equipments covered in the completion report.
2. Test results of main equipments and switch boards.
3. Measured values of earth resistivity at the site before commencing and after completing the installation.
4. Test results of protective relays
5. Test results of insulating oil in the case of all oil containing equipments.
Copies of the following documents shall accompany the completion report.
1. Power allocation from the supplier
2. Sanction under Sec.44 of Electricity (Supply) Act 1948 in the case of generators
3. Approval from the Electrical Inspectorate.
On receipt of the completion report, the Electrical Inspector will inspect the installation and carry out such additional tests as may be found necessary. If the installation is found fit for energisation, the Electrical Inspector will issue the sanction for energisation under R.63 of the IE Rules. Commencement of supply to a new installation is made by the supplier on the basis of the sanction for energisation issued by the Electrical Inspector.
After satisfactory commissioning of an electrical installation, the date of energisation and date of commercial operation shall be intimated to the Electrical Inspectorate department and the electricity Supply authority. In the case of major equipments, the manufacturer of the equipment may also be intimated of the test results and the date of energisation.
