The nonlinear interpretation technique is proposed to detect the fault in transformer windings during the impulse test. To prove feasibility of the proposed technique, 90-MVA 220/110-kV, 250-MVA 500/275/33-kV transformers, and a 22-kV interleaved winding are used. © 1986-2012 IEEE.

The low temperature co-firing compatibility between ferrite and dielectric materials is the key issue in the production of multilayer chip inductive-capacitive filters. A new composite comprising dielectric-ferrite ceramics was prepared by mixing MgCuZn ferrite with BaTiO3 based commercial dielectrics. (Mg 0.25Cu 0.20Zn 0.55)Fe 2O 4 ferrite powder was synthesized through sol-gel auto-combustion method. Commercial Z5U type dielectric powder was used as such. Dielectric-ferrite mixed powder was uniaxially pressed into toroids and pellets. Specimens were sintered at 950 °C. The co-sintering behavior of dielectric-ferrite in composite was investigated using thermo-mechanical analyzer. The co-existence of spinel ferrite and BaTiO 3 pure phases were confirmed by X-ray diffraction analysis. The permittivity of composite continuously decreases and permeability increases with increasing ferrite content. Dielectric and magnetic losses in the composite increased due to the generation of interfacial charges in the ferrite-ferroelectric interface. © 2011 Elsevier B.V. All rights reserved.

Identification and location of partial discharge (PD) source is an important diagnostic tool for reliable operation of transformer. In this paper, future template numerical interpretation techniques are proposed for location of PD pulse duration from 0.1 μs to 5 μs in transformer windings using sweep frequency response analysis (SFRA) principle. To analyze the efficacy of the proposed techniques due to different PD pulses, experimental studies are performed on 22 kV transformer windings by injecting a voltage source of PD pulse across each winding section (tapping). According to Parseval's theorem, energy distributions of the winding responses are calculated to decide on time period/frequency range to be considered for analysis. The measured winding responses obtained due to injection of 1 μs reference pulse across the winding are considered as reference responses. If the PD has occurred any where within the winding, numerical interpretation coefficient has to observe real PD response and make a 'best estimate/best matches' with reference responses through appropriate mathematical formulation. The best matches will give the originating source of PD. To predict the confidence limits and significances of numerical interpretation coefficients output for PD pulse location, hypothesis test and probable error methods are utilized. © 2014 Elsevier B.V.

The BSE Sensex and NSE Nifty fell for a fourth consecutive day as market participants continued to square-up positions following last trading session of the October derivatives expiry on Thursday. Concerns that likely Fed rate hike in December would see outflows from emerging markets, too dampened sentiments. Sensex closed 201 points down at 26,838.14 while Nifty closed 59.45 points down at 8,111.75. In the 50-share index, YES Bank, Dr Reddy’s Labs, Vedanta, Lupin, Ultratech Cement gained between 0.80 per cent and 2.30 per cent. On the other hand, BHEL, BPCL, Axis Bank, Coal India and Gail slid between 2.40 per cent and 4.50 per cent.

Earnings though kept the markets buzzing and there were lots of scrip specific actions based on the performance. Yes Bank gained 1.95 per cent after the bank reported a 26.5 per cent  increase in net profit for the September quarter due to lower provisions and higher net interest income and other income.

The scrip jumped after the company informed BSE that it has bagged an export order worth Rs 125 crore as an initial order of a special range of jewellery for the European markets. Valcambi has a strong marketing network in Europe developed over a period of more than 50 years. Valcambi has agreed to market Rajesh Exports products in Europe provided the products meet European standards and designs. 1.15 pm: SKS Microfinance shares were trading 1.70 per cent up at Rs 432.90. SKS Microfinance will avail its first refinance limit from MUDRA whereby MUDRA (Micro Units Development & Refinance Agency), launched by the Government of India for financing micro entrepreneurs engaged in small business activities like manufacturing, processing, service sector and trade, has sanctioned a refinance line of Rs 100 crore at 10% per annum to SKS Microfinance. The development is expected to contribute to bringing down the cost of interest-bearing liabilities at SKS. Sensex was down 172 points at 26,867. 12.58 pm: Brokers said squaring-up of positions by participants with today being the last trading session of the October derivatives expiry dampened sentiment. A weak trend at other Asian bourses after the Federal Reserve hinted at a possible US interest rate hike in December also hit sentiment.
