Design and Development of Data Acquisition for Leakage Current at Electrical Tracking Test

Abstract—In electrical power systems, the insulator is the material that determines whether the electrical energy can be supplied or delivered to a place of excellent quality and does not harm the human and the environment around such high voltage electrical conductor devices. In testing leakage current in the laboratory, current and voltage changes in input and current changes and output voltages change very quickly, making it difficult to detect with the usual measuring device. For that required software to simulate the test. One method used to test the insulation resistance of the insulator material is the Inclined Plane Tracking (IPT) method. That is a method used to represent the leakage current on the surface of an insulation. The insulation and leakage resistance simulation in this test is performed by Multisim 14 software by simulating the insulation resistance with a potentiometer that changes resistance when a leak current occurs in the test. The resistance is increased step by step to know the parameters of current and voltage at the time of testing. In this simulation testing is done in stages, so it can be known Source Voltage, Input Voltage, Input Current, Leakage Current and Output Voltage. Simulation using Multisim 14 software can represent insulation resistance, leakage current and output voltage that can be used to obtain replacement resistance (Rp), leakage current (Iout), output voltage (Vout), alternating current (Iloss) and replacement voltage (Vloss). Simulation Software Proteus can simulate data received in the form of analog into digital data. Further processed according to the data required.

Currently, epoxy resin has been developing as outdoor insulator replace ceramic and glass insulator, because epoxy resin has some dielectric properties better than the ceramic, glass and porcelain material. When epoxy resin was used as outdoor insulator, some factors affecting performance of epoxy resin insulators are like rain, humidity, ultraviolet rays, condensation and contaminant. To improve the surface properties of epoxy resin, then silicon rubber material that has the ability to repel water were added and silica sand was mixed with silicone rubber to improve the mechanical properties. When contaminant flows at the insulator surface, they can cause damage to the surface of the insulator and it was formed tracking on insulator surface and finally cause flashover. This paper presents the morphological studies of epoxy resin sample test after electrical tracking. The tests were conducted at high voltage laboratory with 3.5 kV AC high voltage and 50 Hz. NH4C1 contaminant was flowed on test sample surface during 6 minutes. After electrical aging was done then samples were taken using SEM devices to be analyzed of morphological condition. The research results showed that epoxy resin material with filled mixtures of silicon rubber and silica 30% (RTV23) did not experience significant damage after electrical tracking by the Inclined Plane Tracking test method

Kepemimpinan Abad 21

Kalau kita mengamati berbagai telaah mengenaikepemimpinan untuk menentukan apa yang melahirkanseorang pemimpin yang efektif dan apa yang membedakanpemimpin dari bukan pemimpin. Literatur kepemimpinanberlimpah, dan banyak itu membingungkan dankontradiksi. Untuk menjelajah hutan ini, kita perlumemperhatikan beberapa pendekatan tentang apa yangmembuat pemimpin efektif
