Abstract

Polymer is now developed as the material replacement of the porcelain isolator and glass insulators. However, tropical climates and high rainfall can cause problems to its. Ultraviolet radiation will continuously accelerate to the surface of the polymer insulator material. As a result, the surface of the insulating material becomes easier letting electric current flow and a fast formation of extensive damage to the surface of the insulator material. Materials used in this study were made from epoxy resin diglycidyl ether of bisphenol-A (DGEBA) as the base material, metaphenylen diamine (MPDA) as the reinforcement material and silica sand. DGEBA and MPDA composition was 30% silica sand filler 30%, 25%, 20%, 15%, 10% and 10% silicone rubber was 15%, 20%, 25%, 30%. The size of the test material was 120 mm x 50 mm x 5 mm. The study was conducted in the laboratory according to standard IEC 587: 1984. This study was conducted to determine the effect of ultraviolet radiation on hydrophobic contact angle and surface damage on the broad value of insulation material epoxy resin silanes. The results showed that the length of exposure time to UV light tended to increase the value of the contact angle. This was due to exposure to artificial UV rays which would accelerate the degradation process. The longer the level of ultraviolet radiation on the sample accelerating the degradation off silane epoxy resin insulators in addition, it caused greater leakage current on extensive damage to the surface of the insulating material.

Abstract

The energy meter is a measuring instrument for measuring and knowing the power of used electrical energy on the load/electrical equipment connected over given time. Digital energy meter is currently in Indonesia is growing very rapidly, the researchers conducted a study to develop a system that can calculate the power and cost .This paper describes a design and simulation of digital energy meter using current sensor ACS712. The motivation of this study is based on the service charging Hand - Phone (HP) in places such as restaurants. HP charging a fee is charged by the absence of clear standards. With this equipment, the cost of charging can be set based on power consumption, as well as the physical form of portable, in addition to the cost per - KWH can be inserted. In the implementation of this research, several steps must be passed, one of which is the initial stage, which emphasizes the conceptual design of the algorithms and hardware. The results of this initial phase are test simulation algorithm that shows the average value of error is less than 1 % , this means that the algorithm can work well and can be used for the next step ( development).
