“…The study on the partial discharge (PD) of solid insulator has been a critical issue to ensure that the insulating function remains in good condition during operation [1][2][3][4][5][6][7]. PD is electrical discharge that partially bridges the isolation between conductors, as result of electrical stress in or on the surface of insulation [8]. PD also one of the factors that could lead to failure of electrical equipment, could destroy insulation and cause ageing of insulation.…”

In practice, field measurement of partial discharge is easily suffered by interferences due to the noisy signal has been mixed with the resulting partial discharge signal. Therefore, the detection and measurement of PD are important to monitor the insulation life in high voltage (HV) power equipment. The paper presents the simultaneous measurement of partial discharge (PD) pulse parameters using the impedance matching circuit and the Rogowski coil sensor to study the features of partial discharge on the epoxy resin insulator. Two different thicknesses of samples were used to observe the PD pulse parameters with the voltage applied vary depending on the thickness of the sample to attain constant electric field intensity for both samples. The step response parameters resulted from the measurement can be used as a time domain features to discriminate various types of PD in HV power equipment. Thus, the PD can be observed clearly, maintenance can be performed, and the performance of the power system can be improved.

This paper presents an analysis of acoustic emission (AE) detection technique for partial discharge (PD) on power transformer using piezoelectric sensor. The AE PD detection technique using piezoelectric material is one of the popular method due to its low cost and compact size. A matching resonant frequency of AE sensor with PD signal which in range 10 kHz to 300 kHz is an important factor for this technique. An AE sensor that have a resonant frequency match with PD signal able to give an optimal performances. Therefore, a simulation on different dimensions of lead zirconate titanate (PZT) AE sensor using finite element method (FEM) is conducted in order to determine the performances in terms of resonant frequency, total displacement and generated voltage. The length of AE sensor is varied from 2 mm to 30 mm in order to reveal the influence of length dimension against generated voltage. Based on the obtained results, that 2 mm length of AE sensor able to generate voltage of 3.01 x10−5 mV at resonant frequency of 113.58 kHz which can be proposed toward PD detection on the power transformer.

The Internet has merged itself as an extremely ground- breaking stage that has changed the correspondence and business exchanges. Presently, the quantity of clients exploring the Internet is more than 2.4 billion. This enormous group of spectators requests online business, learning sharing, informal organizations and so on, which became exponentially in the course of recent years. Accordingly, it prompts the requirement for security and improved protection. As of late, misrepresentation over the Internet comprises one of the fundamental disadvantages for the across the board of the utilization of business applications. Along these lines, the three imperative security issues occur each day in our universe of straightforward design, even more decisively: recognizable proof, confirmation and approval. Distinguishing proof is a procedure that empowers acknowledgment of a substance, which might be either, a human, a machine, or another advantage, for example, a product program. In security frameworks, validation and approval are two reciprocal systems for figuring out who can get to the data assets over a system. Numerous arrangements have been proposed in the writing, from a straightforward secret phrase to late advancements dependent on RFID (Radio Frequency Identification) or biometrics. This paper gives an outline on existing verification techniques, and its upsides and downsides when planning online assistance.
