Abstract:
Earthing means the connection of conductive part of the system with the ground mass to avoid any
accident and smooth functioning of the power system. The act of ensuring effective earthing
resistance is and optimal lightning arrester performance is critical for the safety and reliability of
electrical installations at Busitema University. This project assesses the earthing systems and
lightning protection measures across university structures to evaluate their compliance with
international standards (IEEE, IEC) and their effectiveness in mitigating electrical faults and
lightning strikes. Field measurement of earth resistance were conducted using the Fall of Potential
method, while lightning arrester performance was analyzed through visual inspections, continuity
tests and surge protection efficiency evaluations. The findings revealed variations in earthing
resistance values across different sites, with some exceeding recommended thresholds, indicating
potential safety risks. Lightning arrester were generally functional and some were damaged which
requires maintenance to ensure long term reliability. Recommendations were developed which
included; improving soil conductivity, upgrading earthing electrodes and implementing routine
maintenance schedule for lightning protection systems.
