Implementation of Monte Carlo Simulation in Evaluation of The Uncertainty of Rainfall Measurement

open access: yesPrisma Sains: Jurnal Pengkajian Ilmu dan Pembelajaran Matematika dan IPA IKIP Mataram, 2023
Many factors trigger the uncertainty of rainfall measurement. Several factors can be related to the instruments, weather conditions, and acquisition methods. The degree of uncertainty could be obtained through the calibration process.

Zero‐Sequence current measurement uncertainty in three‐phase power systems during normal operation

open access: yesIET Generation, Transmission & Distribution, 2021
Zero‐sequence currents in high‐voltage power systems during normal operation can have a significant influence on nearby infrastructure. It is therefore necessary to gain insight into typical levels of zero‐sequence currents in a variety of operational ...
