Lightning Protection. If there is no lightning protection system at the installation site, or if an existing lightning protection system is more than 5m from the antenna location, then Customer shall arrange for the antenna and any other ancillary equipment to be connected to an appropriate lightning protection system and ground. Customer shall comply with all applicable laws, rules and regulations. Customer shall further ensure that the IDU has a potential equalization location with a response resistance of < 2 Ohm. Customer shall also prove a cable trunk for the connection between the antenna and internal Equipment. The maximum distance for the lightning/grounding protection system is 5m for both the antenna and the internal Equipment. Cable specification should be Cu / Fe / Ø 10mm. Fuses Customer shall provide fuses in accordance with the following specifications: For internal Equipment 230 V- 16 A As separate circuits with safety sockets For antenna heating (if applicable) 230 V- 10 A As separate circuits with grounding If antenna AC us used 230 V – I 10 A 10 A As separate circuits with grounding Services Not Included in Standard Installation In addition to the other provisions of this Appendix A, the following are not included in the standard installation. If Customer requests GDS to provide any of the following, then GDS will issue a separate quotation for such services. • Any preliminary work • Laying of cable lines • Construction work, e.g. laying of foundation • Fencing of the antenna unit • Assembly of lightning protection • Use and operation of a crane • Disassembly of any existing equipment • Packaging and crating of any removed/de-installed equipment
Lightning Protection. 1. One (1) lightning protection system.
Lightning Protection a. In general, all buildings shall have an Underwriters Laboratories, Inc. approved, Master Label lightning protection system. Where such a system is not provided, complete justification for its elimination shall be made a part of the record.
Lightning Protection. Lightning Protection System shall be provided in accordance with Singapore Standard CP.
Lightning Protection. Buildings will be equipped with an appropriate number of lightning conductors. External inputs to the building such as, cables, pipes, power supplies, ducts, etc. will also be protected against lightning strikes
Lightning Protection. The building superstructure and foundations serve as the main building lightning protection earthing point A lightning protection system is installed to BS EN: 62305:2006 on the roof areas interconnected with foundations by means of connections to the building steel frame. All roof installed equipment is connected to the roof lightning protection system.
Lightning Protection. The Contractor shall furnish and install complete lightning protection systems for the stacks, main plant building, gas turbines, and other outdoor facility equipment and structures, as required. Lightning protection for the switchyard equipment and structures will be by others. The systems shall be complete with air terminals, conductors and ground rods. The installation shall be accomplished by an experienced installer. Design, installation and materials shall be in accordance with LPI and NFPA standards. Surge arresters shall be placed on electric and telephone service entrances, utility lines to the main transformer, service entrances in which overhead lines are utilized, and on all generator leads.
Lightning Protection. Provide and install a complete lightning protection system in compliance with NFPA no. 79 system shall be installed for a UL Master Label A.
Lightning Protection. The SPV power plants shall be provided with lightning & overvoltage protection. The main aim in this protection shall be to reduce the over voltage to a tolerable value before it reaches the PV or other sub system components. The source of over voltage can be lightning, atmosphere disturbances etc The entire space occupying the SPV array shall be suitably protected against Lightning by deploying required number of Lightning Arrestors. Lightning protection should be provided as per IEC 62305 /IS 2309 standard. The protection against induced high-voltages shall be provided by the use of metal oxide varistors (MOVs) and suitable earthing such that induced transients find an alternate route to earth.
