The commissioning of the lightning-safe system makes the school, its building, children, teachers, and surrounding houses in a radius of 107 meters safe from lightning. It will facilitate fearless education, games and extracurricular activities in and around school premises.<\/span><\/p>\n

\u00a0<\/span><\/div>\n

Notably, Mayurbhanj is the lightning capital of India both in terms of lightning occurrences and deaths. Several dignitaries, school staff and students attended the event. It was carried out as part of the \u201cNorth Odisha Tribal Lightning Resilience Programme\u201d led by Maharaja Sri Ram Chandra Deo Bhanj University in collaboration with CROPC, the India Meteorological Department, Ministry of Earth Science, and Fakir Mohan University Balasore.<\/span><\/p>\n

\u00a0<\/span><\/div>\n

It is worth noting that CROPC and IMD are running a countrywide \u201cLightning Resilience India Campaign\u201d to educate people about available solutions to lightning hazards and save precious human and animal lives.<\/span><\/p>\n

\u00a0<\/span><\/div>\n

Villagers of Paharpur apprised that lightning has increased phenomenally and there is always a threat to the life of both humans and animals in the village. The villagers have requested that Pahadpur being a highly lightning-prone village, the entire village should be made lightning safe so that they can have fearless life and livelihood.<\/span><\/p>\n<\/div>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n

The Lightning protection is installed in BOYS hostel, which is a two-floor building with a headroom. There is a SOLAR PV installation as well on the second floor. The proponents claimed that this LPS will protect an area of about 107-meter radius from Lightning, as a result, it will protect the Citizens of that area. The distinguished guests who participated in the inauguration, the teachers and students believed that the installed ESE rod protects the school and the neighborhood up to a 107-meter radius.<\/span><\/p>\n<\/div>\n

2.1 One \u201cESE (Early Streamer Emissions)\u201d air terminal is installed at the highest point of the building, which is at the top of the staircase headroom (say 3rd floor top). Additionally, a non-ESE air terminal is installed in the building, closer to the rooftop SOLAR PV modules on the second-floor top (Fig 3 & Fig 4 respectively). <\/em>There is NO other air termination arrangement (e.g. a mesh or similar arrangement) on the building.<\/span><\/p>\n<\/div>\n

2.2 From the ESE rod, a GI strip runs vertically downwards through the wall of the staircase headroom, further, it runs horizontally above the floor, (which is plastered) Both ESE & Franklin Rod are interconnected, at the terrace of the building (Fig. 5). The second floor has a stainless-steel handrail. Neither the air terminals nor the down conductors are connected to the handrail. There are two runs of GI strips starting from both the air terminals to the down conductor. They are interconnected at the top (Note: GI strip used is 25 * 6 mm)<\/em>.<\/span><\/p>\n<\/div>\n

2.3 Two strips run (parallel to each other at a distance of around 300 mm) from the air terminals as a Down conductor. Along these two Down conductors, a power line in a conduit also runs, hence all 3 together looks like down conductors (Fig. 6, 7 & 8)<\/em>.<\/span><\/p>\n<\/div>\n

2.4 Two down conductors running parallel are connected to two separate earth electrodes (Fig. 10)<\/em>.<\/span><\/p>\n<\/div>\n
