onent, the maximum wind speed observed ( known) on site shall be used, with due consideration for punctual wind events (cyclones, torn adoes, hurricanes, etc.). The PV array structure shall be secured in an appropriate manner or in accor dance with local building standards. The minimum wind flow requirement is given in cl no. 4.1, howev er it shall be observed at site & accordingly the effective loading capacity of the structure on the roof to be calculated. Total Load on the roof of the Building The Bidder shall submit the total weight of structure, array & other accessories taking care of wind load on the roof, according the st rength of the roof to be desi gned. 0.1.1 Earthing system PV array earthing 1 of 1 INDRADHANUSH GAS GRID LIMITED TECHNICAL SPECIFICATION FOR NATURAL GAS COMPRESSOR STATION FOR NORTH EAST GAS GRID PIPELINE PROJECT TS NO.: MEC//2UU/0/2/0 Solar photo voltaic ( SPV) power supply system Chapter-0.1 2, MECON Limited, All Right Reserved Page 1 of 2 General The earthing of the PV system is classified as follows- 1. Earthing of the main current ca rrying conductors of the array (system earthing) 2. Earthing of exposed conductive parts for lightning protection nd/or equi-potential bonding. PV array system earthing In the following Table several configurations are considered. consideration is given to earthing of exposed conductive parts, which covered in the following cla use. PV system earthing configurations Photovoltaic array earthing equipment Application circuit Consequence on the status of the PV array Unearthed Unearthed DC loads Floating Earthed DC loads Fixed to earth AC loads connected via isolated PCU Floating AC loads connected via nonisolated power conditioning unit Fixed by the status of the neutral of the application circuit Earthed * ** Unearthed DC loads Fixed to earth Earthed DC loads AC loads connected via isolated PCU AC loads co
