Embedded Power System Monitoring Of Illegal Power Connections In Kenyan Domestic Supply

Abstract

Globally Technical Losses (TLs) and Non-Technical Losses (NTLs) are a significant challenge for power distribution systems. Mostly NTLs is caused by illegal power connection which can be as much as half of all the energy supplied in some countries. This implies that power generated may not meet the demand and therefore the power utilities are diverting to other types of power generation that are cheaper, reliable and cost effective. High demand for electric power that does not match the current power generated always leads to shortage thus increasing the cost per unit of electric energy consumed. This highly affects the economy of any nation. Most utility company experiences loss of revenue since illegally consumed power cannot be measured or billed. The difference between the total energy sent to the consumers and the sum of energy consumed by all the connected consumers can be determined, and the total amount of NTLs in the distribution line evaluated. Also, the high losses incurred are a burden to the legally connected consumers since it is factored out in their bills. The scenario of NTLs is not restricted to underdeveloped countries and the percentage varies depending with the connected electric users. The techniques used are illegal tap wiring and meter tampering through security seal violations. The existing system in Kenya does not identify the location where illegal connection has occurred. The suggested embedded system will remotely locate the users who attempts to tap power at the service head which is not billed. The system will communicate with the utility company immediately about the status of the affected connection via Global System Communication. This will protect the distribution network in Kenya from high NTLs caused by illegal connections thus lowering the cost of electricity.
