Studi ini dimaksudkan untuk mengkaji pengembangkan desain kumparan motor induksi 3-fasa dengan desain lilitan mengacu kepada desain lilitan dengan jumlah fasa yang lebih banyak dari 3 fasa. Khusus untuk studi kali ini lebih difokuskan kepada desain kumparan 6 fasa yang diterapkan pada motor induksi 3-fasa tetapi arah fluks yang dihasilkan motor dibuat untuk menghasilkan 5 medan fluks yang berbe…
This paper studies the number of lightning strikes in the rocky area tower on the 150 kV Payakumbuh-Koto Panjang transmission line. The intensity of the lightning trip-out on the 150kV transmission line is very high, amounting to 66%. The results showed a positive correlation between lightning trip-outs and the tower-footing resistance in rocky areas. The significant cause of trip-out is back…
Single-phase induction (asynchronous) motors are widely used at home. These motors have two windings and usually operate at a lower performance than 3-phase asynchronous motors which have three windings. For this reason, this study aims to design a new winding of a single-phase asynchronous motor by increasing the number of phases in the motor windings in order to increase the performance of th…
The number of lightning stroke on the tower of the 150 kV Koto Panjang-Payakumbuh transmission line located the rocky area has been observed. The high value of tower footing resistance indicates the occurrence of the back-flashover in the transmission line at intensity of 74%. The back-flashover occurrence is dominantly triggered by the tower footing resistance value. Also, the rate of back-fla…
Lightning is a natural phenomenon that destroys a power line. According to the Sumatra load supplier and handling Center (Sumatera P3B), the intensity the number of lightning strikes on a 150 kV transmission line was very high in Indonesia, reaching 66%. As a result, the isokeraunik level on the 150 kV transmission line in that area is at 174 days/year, and the flashover occurrence rate in its …
The lightning phenomenon is a natural disaster that endangers human life. The nature of grabbing objects closest to the cloud can cause fires, damage to electrical equipment, and even fatalities. The Padang Institute of Technology is a campus that has tall buildings, such as buildings B, C, D, E, and F, without an adequate lightning protection system. This is certainly a concern regarding secur…
