HUMIDITY EFFECTS AND MITIGATION ON GENERATORS IN THE COASTAL AREAS OF NIGERIA
Journal Title: ASIAN JOURNAL OF NATURAL & APPLIED SCIENCES - Year 2018, Vol 7, Issue 2
Abstract
Owing to unreliable electricity supply from the national grid, petrol generators are now an essential part of the energy supply in Nigeria. But Nigeria’s climatic environment affects the operation of these generators. This study investigated the effect of humidity on small petrol generators (rated 500W - 10KVA) in the coastal areas of Nigeria. Climatic data on three coastal states namely Rivers, Bayelsa and Akwa Ibom were collected from the Nigerian Meteorological Agency (NiMET) in Oshodi, Lagos. The data which covered a period of ten years (2008-2017) were analysed using the Statistical Package of the Social Science (SPSS) version 16.0. The stator winding insulation of select brands of generators were tested using the Fluke 1555 Insulation Resistance Tester (IRT). Oral interviews were conducted amongst the generator owners and the generator repairmen to obtain operational information about the generators. The results of the study were represented by appropriate tables and charts. The findings show that small generators in the coastal areas of Nigeria are exposed to high humidity climatic conditions which adversely affect the performance and drastically reduce the designed life spans. The paper suggests regular inspection and scheduled preventive maintenance programs as well as additional ingress protection (IP) to help reduce operational failures as well as boost the life span of the generators.
