The 20 KV PMT (Circuit Breaker) is an important equipment for the reliability of electricity distribution. Therefore it must be maintained so that it is always in good condition with regular maintenance. Prior to maintenance, PMT is terminated from the bus bar, which is called the rack out process. After maintenance, the PMT is reconnected with the bus bar, which is called the rack in process. Usually, 20 KV PMT rack in and rack out process in maintenance or disturbance is still using the manual method. The 20 KV PMT can only be racked in and racked out in one way, by turning the lever. The lever will rotate the bolt as a PMT rail. In the manual method, there is no system for monitoring the condition of the bus bar whether it is has electric-voltage or not. There is also no remote control that can rack in and rack out. So officers must ensure the conditions of PMT and bus bars are safe manually, before maintenance is carried out. This is quite troublesome and dangerous for officers. From these problems, in this research  designed a system that could ensure the condition of the PMT and the bus bar was safe before the rack in and rack out process was carried out and could monitor and control the system remotely using SCADA. Rack-in and rack-out automation system using VT SCADA, using Ethernet Shield that has been connected with Arduino Mega. Ethernet is connected to a mini PC. The microcontroller pins will be connected to the relays that will turn or stop the motor. The rack in and rack out commands from VT SCADA will determine the rotation of the motor so that the PMT moves. The current sensor reads the current flow and detects interference. Interference detection will automatically make PMT Rack out. System testing shows that the process of racking out in a state of maintenance or disturbance can be carried out automatically controlled by VT SCADA. Current sensor works to detect the current flowing, so that it can detect PMT interference and perform automatic rack out. The rack-in process is also capable of being remotely controlled with VT SCADA. This makes it easier for officers to also become additional reliability of PMT in the 20 KV cubicle.

Industrial Relevance

Understanding the behaviour of suspension flows continues to be a subject of great interest considering its industrial relevance, regardless of the long time and effort dedicated to it by the scientific and industrial communities. Information about several flow characteristics, such as flow regimen, relative velocity between phases, and spatial distribution of the phases, are essential for the development of exact models for description of processes involving pulp suspension. Among the diverse non-invasive techniques for flow characterisation that have been reported in the literature for obtaining experimental data about suspension flow in different processes, Electrical Tomography is one of the most interesting, since it presents perhaps the best compromise among cost, portability, and, above all, safety of handling (indeed there is no need to use radiation, which requires special care when using it). In this paper, a brief review and comparison between existing technologies for pulp suspension flow monitoring will be presented, together with their strengths and weaknesses. Emphasis is given to Electrical Tomography, because it offers the above-mentioned compromise and thus was the strategy adopted by the authors to characterise different flow processes (solid–liquid, liquid–liquid, fibres, etc.). The produced portable EIT system is described, and examples of results of its use for pulp suspension flow characterisation are reported and discussed.

The Mathematical Model

In view of the technical development requirements of digital agriculture and the requirement of operation parameter regulation in the operation process of grain harvester. An on-board grain mass flow monitoring system based on pressure sensor was developed. The mathematical model of grain mass and grain flow pressure was established, which realized the real-time measurement, display, and storage of grain dry/wet quality information during the operation of grain harvester. An indoor bench test was carried out with the independently developed grain flow monitoring test bench. The results showed that the output error of the grain mass flow monitoring system was less than 4.25% under the conditions of indoor bench test, which meets the accuracy requirements of grain flow monitoring and provides the decision basis for variable seeding and variable fertilization.

The article continues a series of papers dealing with the investigations into the strength of multi-layer beams under the action of shear [1, 2]. The results of research on the stiffness of timber reinforced beams are presented. As a result of experiments the authorial certificates of five inventions were obtained. One of them is the certificate of the invention SU 1091047 A, G 01 M5/00 “The equipment of experiment of building constructions” [3]; it is also described in the paper. The objective of the experiments was to check the new method of increasing load-bearing capacity of timber multi-layer beams: prestress of separate wooden layers across the axis of the element, described in the above-mentioned papers [1,2]. The results of investigations in stiffness of 28 timber reinforced beams of different cross-section and the way of manufacture under the action of shear are given in the paper. Sixteen beams were tested by static short-time loading and the rest twelve by static long-time loading. All beams failed because of shear. It was determined that deflections of timber reinforced beams under short-time design loads independently on the constructions are much larger (in average 1.48–1.88 times) than those calculated according to the running standards. Because of insufficient evaluation of the shear influence on the deflections the author offers to make it more precise with the help of coefficient k c in the formula (1): for timber reinforced beams without prestressing k c = 2.75, for multi-layer beams with prestressing k c = 1.75. Deflections of timber reinforced beams, of multi-layer beams with prestressing among them at the time of failure under short-time loading are in average 4.75–5.08 times and under long-time loading—5.59- 6.75 times bigger than those calculated according to the codes of practice for the same beams under design loads. Deflections at the time of timber reinforced beams, that have not failed because of longtime loading and have been tested by static short-time loading were smaller than those fixed during a long-time testing under much smaller (0.50÷0.78 V u,t ) loads, but the deflections of the same beams under design loads are close to those (f et /f e =0.97÷0.99) calculated according to the codes of practice. The efficiency of the experiments of building structures may be significantly enlarged when using the test equipment, presented in the invention SU 1091047 [3], the formula of which is as follows: the equipment of building structure test consists of the beam with support, loading and measuring devices and differs in setting of the structure loading devices on different sides of the beam for increasing the effect of the experiment (Fig 7).
