Abstract :
The reliability of the electric power system is related to the quality of the electric
power service to load. for customers or users of electric power, the quality of
service in the show comfort for the user and also the security of equipment used,
with the reliability of the system reliability analysis, to determine frequency of
outages or System Average Interruption Frequency Index
(SAIFI
) conducted
research by using data research assuming customer out of 150 and subscriber
number 350 and micro Arduino uno as a functioning tool to record how many
times the power system went out, then analyzed to determine the frequency of
outage or System Average Interruption Frequency Index
(SAIFI
), Based on the
blackout times recorded on the tool design which then the data in the analysis that
has obtained the results of its SAIFI value is 3,428 blackouts / customers / week
while the electricity network that can be said reliable by the PLN is 3 times
blackouts / customer / year, the value is the value formed by PT PLN (PERSERO
).
