Most of the faults occurring in current transformers are due to insulation failure. Insulation aging is a function of temperature and other environmental factors such as solar radiation and wind velocity. The aging effect is produced by Hot Spot Temperature (HST). The HST value depends on the ambient temperature, the rise in the Top Oil Temperature (TOT) over the ambient temperature, and the rise in the winding HST over the Top Oil Temperature. The winding hot-spot temperature can be calculated as a function of the Top Oil Temperature and that can be estimated using the transformer loading data, top-oil temperature, ambient temperature, wind velocity and solar radiation. This paper discusses the HST with considering environmental factor and without considering the environmental. The loss of life of insulation is related exponentially to the HST. This paper presents the mathematical model of Hot Spot Temperature under variable environmental condition in MATLAB.","PeriodicalId":13702,"journal":{"name":"International Journal of Advanced Research in Electrical, Electronics and Instrumentation Energy","volume":"65 1","pages":"3980-3988"},"PeriodicalIF":0.0,"publicationDate":"2015-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80361024","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We have different applications in microwave frequency range such as GSM, Bluetooth, and WLAN etc.in order to use this applications we need different antenna lengths, but as technology is being advanced the demand of making an antenna which operates in all the above applications is required. To fulfill the demand of above stated antenna, a design of micro strip patch antenna which works under multi frequency of operation using serrated structures has been introduced. This antenna maintains a maximum gain of 7-8dB. The designed antenna has a small overall size of 13×13×0.67 cm, and operates over the frequency ranges, 1.45 GHz,-1.85 GHz, 2.10–2.70 GHz, and 2.82–3.74 GHz making it suitable for GSM 1.8GHz, Bluetooth 2.4GHZ, WLAN 2.4 GHz and Wi-MAX 3.5 GHz applications.

Wind turbines and micro hydro generators with induction generators are considered as an alternative choice. Wind turbines with Self-excited Induction Generators (SEIGs) are increasingly being used to generate clean renewable energy. SEIGs are widely being used in isolated areas (rural areas) to generate electrical energy. Capacitor banks are used with a purpose to provide reactive power for its excitation. The nonlinearity of the magnetizing inductance and the varying rotor speeds necessitates the calculation of excitation capacitance required for voltage build up in a SEIG. This paper presents the various approaches for determining the excitation capacitance and evaluates the value of excitation capacitor for 220/380V, 12.4/7.2A, 4 pole, 50Hz induction machine through various approaches, to build-up voltage for isolated operation of a self-excited induction generator.","PeriodicalId":13702,"journal":{"name":"International Journal of Advanced Research in Electrical, Electronics and Instrumentation Energy","volume":"114 1","pages":"4069-4074"},"PeriodicalIF":0.0,"publicationDate":"2015-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76679971","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The converter uses a switching scheme which operates the switch MOSFET in cutoff and saturation region to reduce power loss across MOSFET. Then, the output voltage is controlled using SM Control technique to get the desired output voltage level. The design is based on low power application such as laptop charger, mobile charger etc. The circuit is simulated using MATLAB/SIMULINK software to obtain desired response.The SM control is a type of nonlinear control introduced initially as a means for controlling variable structure systems. The main advantage of the SM control over other types of nonlinear control methods is its ease of implementation. This makes it well suited for common DC–DC power regulation purposes. The SM control is naturally well suited for the control of variable structure systems. Characterized by switching, power converters are inherently variable structure systems. It is therefore; appropriate to apply SM control on power converters.","PeriodicalId":13702,"journal":{"name":"International Journal of Advanced Research in Electrical, Electronics and Instrumentation Energy","volume":"73 1","pages":"4001-4008"},"PeriodicalIF":0.0,"publicationDate":"2015-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83200971","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The large numbers of drives used for commercial, industrial, residential and utility application are induction motor drive. To run such kind of load energy is required as an input source but due to energy crises solar energy is used as an input energy. To run induction motor with PV source DC-DC converter and inverter is used as an interface circuit. For efficient utilization of solar power SEPIC converter with the P &O MPPT controller is used. The boosted output from SEPIC converter use as an input for inverter. The inverter converts the DC input voltage to AC output voltage for the induction motor. To minimize the harmonic from the inverter output voltage, various types of MCSPWM techniques use to generate the firing pulse for the switches of the inverter.

The main component of the CVT are the capacitive voltage divider, a tuning reactor, a step down voltage transformer, a Ferro-resonance suppression circuit and the burden made by the relay. CVT are used for protection of high voltage lines, substations and transmission of high frequency signals. These applications required low voltage signal, which is given by output of CVT. The CVT applications require fast and secure protection. The energy storage elements like inductors & capacitors cause CVTs to exhibit transient behaviour. Further the performance of protection devices is also affected by the transient of CVTs. In steady state, the secondary voltage of a capacitor voltage transformer mirrors the primary voltage. Because of the energy-storage elements used, the transient output, caused by sudden change in primary voltage, is no longer a replica of the primary. Transient over voltages, which exceed insulation ratings can stress electrical insulation, leading to abrupt failure or gradual breakdown of the dielectric of electrical component. This paper attempts to study the effects of changes in capacitor values on the transient response of the CVT. Furthermore, the various method which affects the transient response are discussed by simulating the mathematical model using MATLAB","PeriodicalId":13702,"journal":{"name":"International Journal of Advanced Research in Electrical, Electronics and Instrumentation Energy","volume":"30 1","pages":"3993-4000"},"PeriodicalIF":0.0,"publicationDate":"2015-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87328739","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
