D. Makanju mooyeleye@futa.edu.ng <p>Earthing system are used to divert faulty currents to the ground or earth. Thus, a properly designed earthing system capable of dissipating fault currents safely to the ground or earth is required for safety of life and property hence the focus of this project in determining earthing resistance/resistivity adequacy of a Proposed School of Environmental Technology Building (PHASE III), Federal University of Technology, Akure, Nigeria. 4-point measuring technique, Wernner method, using digital earth tester, model 6472-AEMC is used in this work. The site is divided into five transverse for the tree buildings on site. The result shows that the earthing resistance of one building (transverses 1 and 3) generally varies from 3.9? to 54 ?, second building: 2.3? to 11.9? and for third building: 2.2? to 6.4 ?. Of the samples taken, building 1, 2 and 3 conformed to 4%, 47% and 50% of International Electrochemical Standard (IEC) and 48%, 60% and 100% of British International Standard (BIS). Transverse 5 is the best transverse for earthing because 50% of the points met IEC and 100% of the points met BIS standard for earthing resistance value. Earthing rod or mat can be installed at some points in building 1 and 2 in their transverse but not at every point but at any point in building 3 transverse. Earthing rod or mat at can be installed at 150mm (minimum) in the transverse that meet up the international code’s resistance value requirement.</p> <p>The result also establishes that resistance is directly proportional to soil resistivity, the lower the earth resistance the lower the soil resistivity. Building 3 which is closest to swamp area has lower resistance value (2.2?). The site is okay for earthing without any earthing improvement. Earthing resistance value test should be carried out on site prior earthing installation.</p> 2020-03-14T14:45:06-04:00 Copyright (c) 2020 Oyeleye Matthew Olayinka, T. D. Makanju https://ejece.org/index.php/ejece/article/view/196 Multifactor Violator Model. Condition-factors and Resource-factors 2020-04-05T11:08:12-04:00 Oleksandr Kireienko kirealex12@gmail.com <p>Attack scenarios with limitations were investigated. Resource-factors and condition-factors were set as two types of limitations. Resource-factors are spent at each step of attack and can be replenished completely or partially if a given attack step was successful. A situation, where successful completion of current step with one or more preceding ones is required to replenish resource-factors, is possible. After each step of attack the violator can “exchange” resource-factors to accumulate the required amount of those factors for the next step. The lack of the required amount of resource-factors may either forcefully interrupt an attack or to lower success probability or reduce the time required by protection side to discover the consequences of an attack. This article doesn’t consider the change of relative cost of resource-factors, that is caused by urgency, so that all resource-factors have fixed cost regardless of violator’s reserve of these resource-factors.&nbsp;</p> <p>Conditions-factors are fixed limitations for conducting an attack. Discrepancy of condition-factors makes it impossible to either start an attack or to finish the current attack’s step. In certain cases the lack in one condition-factor can be compensated with excess of another condition-factor or via spending additional resource-factors.</p> <p>The influence on resource-factors and condition-factors is laid as a basis of protection strategies. The strategy of increasing the values of condition-factors for violator decreases the total amount of attacks on a system by screening beginner violators. The threat level from groups of violators and from experienced violators will remain unchanged. The strategy of increasing the rate of resource-factors spending is designed to interrupt attacks in progress. Strategy of decreasing the amount of resource-factors that can be replenished after successful completion of certain steps of attack scenario is meant to decrease violator’s interest in attacking specifically our system and to decrease the chances of attack repetition if an attack occurred.</p> 2020-03-14T14:56:09-04:00 Copyright (c) 2020 Oleksandr Kireienko https://ejece.org/index.php/ejece/article/view/199 The Moving Average Filter of Stator Current as Alarm for Overload of Induction Motor 2020-04-03T15:33:10-04:00 Goran Kekovic kekovic221@gmail.com Negovan Stamenkovic negovanstamenkovic@gmail.com <p>In this paper, the method of detecting the overload of the induction motors (IMs) by applying moving average filter of the stator current in the time domain, was suggested.&nbsp; This method can be analyzed as the part of the analysis of the motor current signature analysis (MCSA). The stator current is analysed as the signal and it is divided into regular intervals – windows, within moving average filter applied.&nbsp; The minimum length of the moving window is determined by the sampling frequency detector, as well as the frequency of the stator current. The better resolution of peaks in moving average filter, can be achieved by the greater length of moving window. This is particularly important in areas of variable torque induction motor. This opens the possibility of detecting finer changes in the value of the stator current. It is shown that within the time window of changes in load of IMs, the signal of stator current becomes non-stationary. Otherwise, it is stationary. The changes of stationarity of the signal could be the alarm of overload of induction motor. The advantage of this method is improved response time of detector due to changes in the stator current. Software solution of proposed method is relatively simple: time series of the stator current is mapped according to the action of the moving average filter in different time series, suitable for use in real-time. &nbsp;</p> 2020-04-03T15:33:10-04:00 Copyright (c) 2020 Goran Kekovic, Negovan Stamenkovic
