This work presents an attempt in developing a non-electrical contact and non-invasive type, portable fault diagnosis unit for Induction Motor (IM), using OMAP digital signal processor and Micro-Electro-Mechanical-Systems (MEMS) accelerometer. The novelty of the work lies in the fact that several electrical and mechanical faults can be successfully detected in order to deal with challenges in the continuous condition monitoring of incipient faults in IM. The methodology includes capturing of vibration signal by accelerometer, conversion of vibration signals to voltage signal and taking the FFT of the signal in digital signal processor to carry out the spectral analysis. The experimental results have been validated by comparing with the results of Tektronix FFT analyzer and simulation. Further the developed system was examined on IMs at Milk processing dairy industry and Ply wood manufacturing industry to validate the system performance.

With the dynamic drop test method (DDT), the hydrophobicity retention of polymeric insulation materials can be evaluated under stress with droplet under electrical field stress, which results also to droplet corona stress. The CIGRE WG D1.58 carried out a round robin Test (RRT) with the aim of clarifying the reproducibility and repeatability of test results (hydrophobicity retention) with this method. In the participating laboratories, retention times were determined on the same insulating materials, which have both a very good agreement and considerable deviations from one another. Even with repeated tests in a laboratory, different retention times are sometimes measured for identical technical insulating materials, whereby the reason for this was not fully evaluated up to now.For this reason this investigation shows the research work based on evaluation of possible reference materials to check the repeatability and reproducibility of different test stands and different test locations.
采用动态滴落试验方法(DDT)，在电场应力作用下，用液滴来评价聚合物绝缘材料的疏水性保留率，从而得到液滴电晕应力。CIGRE WG D1.58进行了一轮循环试验(RRT)，目的是澄清该方法测试结果(疏水性保留)的再现性和可重复性。在参与的实验室中，在相同的绝缘材料上测定了保留时间，两者之间既有非常好的一致性，也有相当大的偏差。即使在实验室中反复试验，有时对相同的技术绝缘材料测量不同的保留时间，其原因至今尚未得到充分评价。为此，本调查显示了研究工作的基础上评价可能的参考物质，以检查不同的试验台和不同的试验地点的重复性和再现性。

In sodium cooled Fast Breeder Reactors; power control is achieved through control rods which are driven by Induction motor with Electromagnetic brake. The motor will be energised upon release of brake unit. The brake coil will be energised to release the brake. The coil is of 48 V DC. If the brake is not released properly due to low flux developed in the brake coil, inter-turn short, liner wear; then there is a chance of Induction Motor getting damaged due to high frequency Surge generated due to interruption of locked rotor current. Hence the performance of brake unit in this application is highly critical. Voltage build-up time for brake power supply is checked. Magnetic field developed by various EM brake units has been measured and plotted as a function of applied voltage. Brake coil has been modelled in FEMM and Electromagnetic Finite Element Analysis has been carried out for determining the number of turns and fill factor of the coil. Brake unit has been dismantled and the effect of brake liner and the friction plate on pulling force of coil is observed. The same has been simulated in FEMM for computing the EM force on movable armature (disk) at various distances from the brake coil. Experiments and simulation results were used for diagnosing the cause of non-release of the EM brake. This paper discuses various causes of failure to the brake unit and to avoid recurrence of similar failure event.

Transmission system is of vital importance that they should function reliably year in and year out. High voltage DC cable systems act as the backbone to power transmission system particularly to transmit wind power from offshore to load Centre with reduced loss. Cross linked polyethylene though most widely used insulation material for cables, is non-recyclable one. As the environmental concern are on the rise, to use a recyclable material, Isotactic polypropylene (i-PP) is identified as one of the a recyclable material. This has the advantage of operating under high temperature as well. Nano composite thin films for this work are prepared with i-PP as base with various weight percentages of TiO2 and ZnO nano particles. These specimens are subjected to stresses provided by (i) HVDC (ii)High frequency AC (10kHz and 20kHz), (iii) Superimposed stress (HVDC and High Frequency AC). Sample stressed with high frequency AC leads to rapid degradation. Polymer Nano composite with TiO2 filler is found to have higher resistance to insulation degradation compared with ZnO filler.

Inductors utilizing the nonlinear properties of ferromagnetic materials may also be made to perform as switches. These function as magnetic switches which decrease the circuit impedance for the compression of current pulses in time domain. These have been employed in pulsed power applications such as radars and lasers. The nonlinear inductor being robust, relatively inexpensive and having a comparatively long lifetime, have an advantage for operation in certain applications over the conventional switches. In this paper, the authors have developed a magnetic switch which utilizes an inexpensive and readily available material – M5 electrical steel as saturable core.

Due to the cyclic loading of the transformer the ambient air flow through the conventional dehydrating breather. Ambient air contains moisture and due to the poor conditions of the breather, it leads to deteriorate the insulation life of the transformer. In the proposed work, a capacitive parallel plate relative humidity sensor for monitoring moisture inside the breather has been designed. The sensing film between the parallel plates of the sensor is of porous hexagonal ordered structure. It was grown through the anodization of aluminium (Al) by electrochemical fabrication method. Moisture inside the breather was monitored with the help of designed sensor. A phase detection electronics circuit for converting the capacitor change of sensor into the voltage signal was designed. The designed sensor was used in estimating the dehydrating efficiency of 0.5 kg breather used in < 200 kVA transformer for the duration of 44 days. During this period, the steady state response of the moisture inside the breather was also analyzed. With the help of designed sensor and phase detection electronics circuit, the condition monitoring of the breather of the transformer will be possible and reduces the visual inspections of the degree of moisture inside the breather.

Condition monitoring of induction motors has been one of the prime focused area in recent years for its utility and effectiveness. The main aim of this article is to find out induction motor faults in incipient stage, so that uninterrupted hazard free operation could be achieved. It is found that different types of faults could not be precisely identified by Motor Current Signature Analysis (MCSA) using FFT analysis alone. In this proposed work, fault related information is extracted from Park’s Vector Modulus (PVM) current using Discrete Wavelet Transform (DWT). Different DWT coefficients are generated with specific time-frequency resolution to segregate different fault information features. DWT coefficient helps to generate more fault features using statistical methods. Overall, this method shows reasonable accuracy in fault identification by implementing different types of classifiers.

Kraft paper is one of the most commonly used insulation in transformers and cables. Impregnation with transformer grade mineral oil is done to improve the electrical properties of the paper. Voltage endurance coefficient (n) is used to estimate the performance characteristics of the insulation paper aging. In this paper, a comparative study is done to estimate the endurance coefficient using conventional V-t curve method and Damage Equalization Method (DEM). The endurance coefficient is also known as the power law coefficient which is used in the V-t curve method to characterize the insulation aging. The unknown power law coefficient is also obtained from known values of step durations and stresses for each sample till its breakdown under DEM. Various types of AC Breakdown tests were performed on cable insulation of different ages obtained from a local manufacturer.

Underground cables are widely used in urban areas for electrical power transfer, and some of those cables are very old. These cable insulations are often subjected to partial discharges due to aging which, gradually degrades dielectric strength of the insulation and ultimately results in complete failure. Therefore, detection of partial discharge (PD) within the insulation of cross-linked polyethylene (XLPE) cable may help to get an early warning about the fault condition. This paper reports about initial results obtained from the measurement of PD activities within XLPE cable using standard electrical method and UHF method.

Detection and diagnosis of faults in Induction Motor Drive System (IMDS) is critical in industries to avoid unexpected production shut down and subsequent financial losses. This paper presents the design and development of an intelligent, fuzzy based decision support system to detect multiple switch open faults in the drive of IMDS. The proposed technique is developed by systematically analyzing various combinations of multiple switch open fault cases under different loads. The root mean square value of the stator currents together with its Total Harmonic Distortion (THD) are unveiled in this study as the decision variables to accurately transpire various fault conditions. As the functional relationship between the extracted parameters and fault condition cannot not be mapped using binary variables, fuzzy logic is adopted to distinctly identify the fault in the drive. The developed system is tested using MATLAB/SIMULINK. The proposed system is competent to provide the plant operators with timely and informative operational guidance, enabling them to make accurate diagnostic decisions.
