Solvent free high solid coatings are increasingly used as they posses number of advantages such as, lower cost per unit film thickness, better performance and eco-friendliness. In the present study polymeric film-forming materials such as aniline-novolac (ANS), cresol-novolac (CNS) and acrylic copolymer blended cresol-novolac (ACNS) coating materials have been prepared. The corrosion resistance properties of the prepared high solid coating materials have been evaluated through potential-time, potentiodynamic polarization and electrochemical impedance studies (EIS). Among the three coating systems, cresol-novolac polymer coated substrates offer better corrosion resistance property and the order of the performance was found as CNS > ACNS > ANS. We can recommend these systems for use in automobile applications.

IEC 61850 based substation automation system mainly consists of a various of protective and control IEDs. In order to implement the system, All of them should require the performance verification of IEC 61850 communication services for the assurance of interoperability throughout the digital network. This paper shows a research result on the testing method of IEC 61850 control communication interface of IEDs according to IED IEC 61850 conformance test procedures.

The protection for copper tarnish was developed by surface treatment method and volatile corrosion inhibiting (VCI) technology. The performance of surface treatment and VCI material is also examined in simulated test environment. Benzotriazole (BTAH) solution that contained molybdate showed best performance than others. Usage of VCI materials with surface treatment was more effective. The protection film foamed on the surface of copper was investigated by auger electron spectroscopy (AES) and X-ray photoelectron spectroscopy (XPS). Molybdate does not participate in the formation of the protective film but promotes the passivation effect. This facilitates the stabilization of the cuprous oxide film, and strengthens the adsorption of BTAH.

The measurement of electric current using optical techniques provides a number of important practical advantages including effective isolation from high line potentials and freedom from the saturation effects observed in conventional current transformers. In this work the optical current sensor which uses thin YIG(Yittrium Ion Garnet) film as a Faraday element has been developed. We have characterized this optical current sensor and implemented it to the OOCR(Opto-electronic OverCurrent Realy) Performance of the OOCR shows the possibility of replacing the present overcurrent relays with OOCR.

The main aim of the paper is the study of the surge voltages in electric railway signal security system. Hence these studies will provide means of introducing a suitable protective device insulating transformer. This influences the surge voltage interrupting capacity using surge arresters and bypass capacitors. This circuit can be used for investigating surge phenomenon in electric railway signal security system. In this paper a insulating transformer has been introduced for the reduction of surge voltages in the above circuit model and performance evaluation.

To prevent the rusting of steel, a variety of finishing materials has been applied. When steel is exposed to an extreme chloride environment, however, the thermal performance and aging of the finishing materials cause the material to lose its rust protective performance. In this study, an accelerated corrosion test was performed on five different finishing materials for steel, to determine the critical values of corrosion. As the result, the critical value of corrosion was found with no coat between 0.58mg/d㎡ and 0.73mg/d㎡, with urethane coat between 7.89mg/d㎡~8.46mg/d㎡, with one-layered red lead coat between 57.95mg/d㎡ and 69.48mg/d㎡, and with staleness201 between 80.73mg/d㎡ and 89.35mg/d㎡.

In recent years, with the continuous development of modem power system, the need for high performance protection to meet the customers' requests for more stable and reliable power supply has become increasingly emphasized. So, there is urgent need for a proper testing platform about not only existing digital protection relay but also new digital protection relay on the transmission line. It is also dynamic-state test which can test the performance of digital relay. This paper suggests basic system model for testing transmission line protection using PSCAD/EMTDC, and presents the process of the component modeling in the basic system.

'KRS 6330-3256라' standard regulates performance test of insulating transformer for protecting the electronic interlock linkage equipment which is being done by test procedures and methods according to the standard. The balance/unbalance test evaluating the performance of transformer are applied by impulse voltage($l2/200{\mu}s$) but affected by many other factors. Therefore, the review about these is necessary to have the reliability and reappearance of test results. In this paper, we have simulated about several phenomenon appearing in real balance/unbalance test and compared simulated results with real ones. With the basis of these results, the influence to test result of inner and outer factors are investigated and analyzed and established the plan boosting the reliability and reappearance of test results.

Surge protective devices can be divided into three categories based on the circuit assembly: a parallel circuit type that considers the surge current amount within the device, a series circuit type that considers the voltage and single circuit type that uses a single element. However, when assembling SPDs, there are many things including function and safety to be taken into consideration because they are directly related to the performance and safety of the device. In this paper, we executed an experimental comparative study of performance and thermal stability of each SPD type using lightning surge generator and thermal image camera.
