This study was aimed at explaining the effect of discount price on purchase intention and consumer's perceived risk as mediator. This study was using Explanatory Research and Quantitative approaches. The variables of this study were discounted price, purchase intention, and consumer's perceived risk. The population in this study was Shopee user who is aware of the flash sale program and has the intention to buy. Incidental sampling is used to determine the sample with 250 respondents that had been counted with infinite population formula. Furthermore, the researcher used online questionnaire as the data instrument. Meanwhile, path analysis and descriptive analysis were used as the data analysis technique to find out (1) discount price, customer perceived risk, and purchase intention on Shopee flash sale program, (2) Direct effect of discount price on consumer's perceived risk, (3) direct and indirect effect of discount price on purchase intention, (4) direct effect of consumer's perceived risk on purchase intention.

Continuity of power transmission is important to ensure the reliability of the electricity supply. As most system faults are temporary, the auto reclose (AR) scheme has been used extensively to minimise the outage duration, prevent widespread outages, thus increase system stability. Meanwhile, the hybrid transmission line (HTL) combining overhead line (OHL) and high voltage cable has been introduced to provide an inexpensive solution for an urban power grid. Protecting HTL with a conventional protection system would forbid the operation of the AR scheme due to difficulty to ensure whether the fault occurred on the OHL or cable section. Therefore, the circulating current protection (CCP) scheme is used in the cable section to ensure the fault location and block the AR scheme. The technology of an optical current transformer (OCT) as one of the non-conventional instrument transformers (NCIT) has emerged to provide a solution to drawbacks on the conventional current transformer (CCT). Consequently, this paper investigated the impact of using OCT over the CCT for CCP of the HTL. The result shows that OCT could be used for CCP on much longer cable sections thus increase its reliability as the AR scheme can be used on longer or multiple cable section.
