Grounding System Sample Clauses
Grounding System i) All ground connections shall be checked and the entire system shall be checked for continuity. The resistance of the ground system at each site shall be measured using a 3-point fall-of-potential method. The maximum ground resistance shall be three ohms.
ii) Ground tests shall meet the requirements of the California Electric Code, Article 250.
iii) All PV system grounding shall meet the requirements of CEC Article 690.
Grounding System. Perform electrical resistance testing to verify continuity of grounding systems. Measure current on ground cables and test for ground faults.
Grounding System. Inspect grounding system connections for mechanical and electrical integrity, corrosion, and damage. Spot check torques.
Grounding System a. A site survey shall be performed to determine the grounding grid design for the station.
b. A ground grid shall be provided for the plant and shall be in accordance to latest NEC standards. The plant and substation fences shall be grounded.
Grounding System o.1) New substations must have a deep grounding grid securing personnel against contact voltages. At the same time, the grounding grid should allow the safe discharge to land of lightning over-voltages without the equipment installed being affected.
o.2) The expansion and connection to the grounding system in existing substations is included in the scope.
o.3) All items of all the equipment without voltage will be connected to the grounding grid. o.4) All arresters will be also connected to individual ground electrodes.
Grounding System. A grounding system should be provided to discharge static charges accumulated in the DCP structure and provide a stable voltage reference for the equipment, following the standards NBRs 13.571/96, 5426/85, 5456/87, 6006/80, ASTM E 478, UL-467, or other standards ensuring equal or superior quality. The grounding system planned should have the following minimum characteristics:
a) Solid copper cable, 3.0 meters in length, and nominal section of 35 mm2 (total of 1 unit per DCP);
b) Grounding rod composed of a carbon steel core, ABNT 1010 to 1020, coated with at least 0.25 mm of electrolytic copper layer with at least 95% purity, no traces of zinc, 2.4 meters in length by 1/2" in diameter, with a beveled tip (total of 1 unit per DCP);
c) The rod should not present cracks or displacement of the copper layer when bent at an angle of 30°.
d) Devices to connect the copper cable to the DCP box and the rod.
e) Connectors between the grounding rod and the copper cables should be of the "U" type, with an area of 1/2" for the grounding rod, as shown in the image below: Photo of connectors The grounding rod should be delivered tied inside the 3-meter galvanized tube used as the support rod for the DCP.
Grounding System. CROWN will install a buried Site ring in accordance with Ericsson standards (to be provided by TRITON to CROWN)and provide a coiled length of ground wire to connect to TRITON's BTS equipment. CROWN will install all other required external grounding. Ground ring connections will be cadwelded except the connection to the master ground bar and all coax grounding kit connections will be mechanical. Notwithstanding the foregoing, all grounding shall meet or exceed Ericsson grounding requirements identified in Exhibit "I-I-B-i".
Grounding System i. Replace two defective exothermic weld connections. (completed prior to 8/17/04)
ii. Modify the plant’s maintenance program to include periodic evaluations of the grounding system and visual checks of all accessible exothermic weld connections. (completed prior to 8/17/04)
iii. Test and repair as part of regular preventative maintenance.
Grounding System. 8.3. A The Contractor shall re-connect all necessary equipment and hardware to the grounding system and install new grounding connections as indicated by the Contract Standards and drawings or any requirements of the Contract.
