An Analytical Method for the Analysis of Transformer Windings Having Non-Uniform Capacitance Distribution
Abstract: A direct procedure for the transient and frequency analysis of transformer windings with location-dependent inter-turn capacitance distribution is presented. This can help simulate windings with non-uniform insulation. The derived analytic solutions in the Laplace domain are based on expressing the non-uniformly-distributed series capacitance per unit length as the sum of a constant term and a variable part proportional to the square of the distance from the winding’s source terminal. The …

Linear Programming based Model for Design of Looped Water Distribution Networks with Redundancy
Abstract: A new linear programming based two-phased methodology is suggested for design of looped water distribution networks with redundancy. The redundancy is provided against failure of pipes and a network is designed to sustain failure of any one of the link without affecting nodal supplies in a part or full. In the first phase, network is designed under normal pipe working conditions for assumed flow distribution using linear programming. The performance …

Single-Server Queueing Model with Non-Homogeneous Compound Poisson Bulk Arrivals with Intervened Poisson Distribution
Abstract: Queuing models are used to analyse the practical situations in communication networks and transportation in a sophisticated manner. In most of the cases, the arrivals are time dependent and can be characterised by a non-homogenous Poisson process. In this paper, for the performance measures of a single-server queuing model with non-homogeneous compound Poisson bulk arrivals have been studied with intervened Poisson distribution. Sensitivity analysis has been carried out. It is …

An Exact Kolmogorov–Smirnov Test for the Logarithmic Series Distribution with Unknown Parameter
Abstract: AbstractIn this paper, we develop an exact Kolmogorov–Smirnov goodness-of-fit test in the case of logarithmic series distribution with an unknown parameter value. This test is conditional, with the test statistic being the maximum absolute difference between the empirical distribution function and its conditional expectation given the sample total. Some modifications are done on an algorithm previously proposed in the case of the Poisson distribution and used the modified algorithm for …

Voltage Vigilance: Ensuring Balance and curbing Theft in Power Distribution Networks
Abstract: This project proposes a system for detecting electrical overload and earth faults using an Arduino Uno controller. The system uses a current sensor to identify overloads and a voltage sensor to detect earth faults. An ESP8266 module allows users to switch between the two fault detection modes. When an overload is detected, the Arduino turns off AC bulbs using a relay and sends an alert message via a GSM module. …
