Common use of REGULAR VISUAL INSPECTIONS Clause in Contracts

REGULAR VISUAL INSPECTIONS. The Concessionaire will carry out visual inspections to identify line sections that present high levels of surface contamination in conductors and chains of insulators. Inspections shall cover the entire length of the line and shall be carried out at least once a year. OSINERGMIN has the power to witness the inspections and request their repetition, if necessary, in order to verify the reported contamination level. The levels of conductor and insulator contamination will be classified as Low, Medium and High, pursuant to Table 1. The procedure for conducting visual inspections is as follows: a) Inspections will be carried out by specialists in transmission lines, equipped with safety equipment, binoculars and digital camera with date stamp. b) Inspections will be carried out only during the day, with the presence of sunlight, absence of rain, low humidity and no strong wind. c) The technician in charge of the inspection shall be located on the ground at a distance of 30 to 50 meters from the line axis; using binoculars, the technician will observe contamination accumulation on the surface of conductors and insulators in the three phases of the span. If necessary, he/she will carry out the inspection climbing up to the line structure. d) Particular attention must be paid to the installation points of spacers and dampers, in order to verify conductor condition at attachment points. e) According to Table 1, the technician will rate and record the conductor and insulator contamination level in the logbook. f) If contamination level is Medium High, the technician will take a photographic record. g) The steps indicated in (c) to (f) shall be repeated for each of the other spans of the inspected line until 100% of the sections to be inspected are completed. h) The Concessionaire will verify the contamination rating reports and group the sections by contamination levels of. If there are observations on the rating, reassign the correct rating by using the photograph or, if such is the case, a new field inspection will be carried out. “Año del Buen Servicio al Ciudadano” Low Minimum contamination, there are no accumulation spikes Medium Visible contamination with small contamination spikes along the conductor High Visible contamination with large accumulation spikes Visual inspection reports will be submitted to OSINERGMIN.
