3. Insulation material: made from XLPE and isolate between the three phases, its thickness is about 5.5 mm along the cable 4. Outer semiconductor: uniformly distribute the voltage on the surface of the insulation 5. Earth layer: made from copper, used to ground the cable, in case of short circuit it protect the cable by leaking the short circuit current into the ground, its thickness is about 25mm2 area 6. Filling: synthetic fibers used to make the cable circular and to fill the gap between the phases 7. Inner layer: made from PVC, collect the phases of the cable and make the cable circular and protect the cable from the armouring 8. Armouring: Steel wire is used to wrap around the cable to protect the cable from the stresses and mechanical effect 9. Outer cover: PVC layer used to protect the cable from the external effects of the soil and the land and prevent the moisture and water from reaching the inner components of the cable Fig 32 medium voltage three phase cable isolated by XLPE Components of medium voltage single core XLPE cable: as shown in Fig 33 1. Conductor: stranded wires from copper or aluminum with a suitable cross sectional area relating to the ampere of the load 2. Inner semiconductor: uniform and distribute the electric field to prevent interference between …show more content…
• Then the fault cable is tested to determine the type of fault, 18 KV is applied on each phase for 5 minutes, if the phase can carry this voltage, so this phase is good and no fault on it, if the phase cannot withstand this value of voltage, this means that the insulation is damaged and this phase is faulty, If one or more phase cannot withstand the 18 KV then these phases are faulty and the type of fault is short circuit due to breakdown of the insulation, but if the phases withstand the 18 KV applied but the current from the sending end not reach the other end, this means that there is an open circuit fault which is may be break in the conductor or the joint connecting the
1. Planning Before you want to jump right into planning, you want to meet with your client to talk about the project, you want to obtain certain information so that it can help you learn more about the project and whether or not the project should go ahead. Once you accept doing this project, you want to make sure that the client knows the requirements you’re looking for and whether they will meet your standard. For example, your payment estimates for future stages of the project.
Measure the capacitance of the open-ended coaxial cable 3. Determine Ra and Rb to meet the amplitude and time constant specifications. 4. Measure the Gain and time constant (Tau), and compare the the measured data with the calculated data, which based on experiments. Instructions: 1.
consistent operational outcome of manufacturing facilities. The 5S system consists of “sort”, “straighten”, “shine”, “standardize” and “sustain”. Every production line in Macfood Services has own a team of HHP that consists of production line manager, executive, QA and maintenance engineer. I was assigned under production Line 6 and Line 7 HHP team.
Note that in the above equations, the $R_{sp}(b_j)$, $\forall b_j \in B$, $RB^M(u_i)$, $\forall u_i \in U$, and $RB^S(u_i)$, $\forall u_i \in U$, are unknown variables. The objective function of the above formulation is to maximize the estimated total amount of data, i.e., to maximize the network throughput. The constraint C1 restricts the split data rate $R_{sp}(b_j)$, $\forall b_j \in B^C$, should be less than $b_j$'s input data rate $R_{in}(b_j)$. The C2 demands that the $D^M_p(u_i)$ cannot be larger than the summation of (i) UE $u_i$'s input data volume at MeNB in the upcoming $I_t$, i.e., $R_{agg}^M(u_i) \times I_t$ and (ii) the remaining data located at MeNB $D_r^M(u_i)$. The C3 restricts the $D^S_p(u_i)$ on SeNBs, and the idea is similar

We have represented the data collected during our spectrum measurement by using a N $ imes$ M matrix designed by L.

It is made of scrap iron heated by means of open heart furnaces and woven. In the 1870’s Charles Wickwire began his primitive weaving of wire into screen. In the 1880’s Wickwire and his company started creating wire cloth suited for door and window screens composed of steel wire, which was either painted or galvanized. This item would have been made very cheaply depending on the price of iron.
• Ensure service members’ records were filed properly and maintained in the individual record. • Procure service member records in-order to be mailed out to other claim offices, having major effects on individuals. • Ensure all regulatory requirements pertaining to individual privacy were adhered to. • Research and obtain all necessary paperwork and relevant information regarding cases and issues pertaining to individual records. • Identify records, inconsistencies and initiated actions to correct the problems.
• Giving an orderly review of the current procedures for IDS, and the way in which these have been connected to IoT. • Exploring the future difficulties for IoT and the part that IDS can play. • Outlining the key zones where future research can enhance the utilization of IDS in IoT. Whatever is left of the paper is dealt with as takes after, Section 2 demonstrates the related works that have proposed the outline and overview about IDSs.
After compiling all of the ingredients into a numbered list, I find out that every product “purchased” at Harris Teeter would account for $116.19 over the budget. The few adjustments I made to my shopping list beforehand did not help reduce the total to a reasonable price either. While I was going through all of the products at home, I crossed out a few unnecessary items that were optional or switched to products with a lower price just to see if I could be within the budget. Eventually, after I was done “shopping” and tallying up all of the prices, the cost still exceeded the price that I calculated in my head. As I went down the aisles searching for foods on my grocery list, I kept a close eye out for products that had nutritious labels such as organic, fresh, or low in sodium so that the college student I chose could receive the right amount of nutrients needed for a healthy lifestyle.
The difference between the two and three-tier client/server configuration, are the tiers (layers) that make up the systems. In a two-tier system you have a client and a server, each has the capability of doing the processing for the application (Brown, DeHayes, Hoffer, Martin, & Perkins, 2012). The software is loaded on the client computer, and access the data server directly. In a three-tier system, there is an additional server/computer between the client and data server; this third component contains the business logic or processing for the application (Brown, DeHayes, Hoffer, Martin, & Perkins, 2012; Luke, n.d.). A three-tier configuration could be a web-enabled business application.
Unit 5’s reading section covers the various features and tools available in Microsoft’s Powerpoint application (Gambrel, 2014). The first part I found helpful was the section that taught how to create a new presentation. This taught me several things about Powerpoint including how to add, delete, and organize slides. I have used Powerpoint in the past, but everything I know about it is self-taught, so it was good to have an actual training that covered everything from scratch.
Commercially, pure copper was easily producible, making it cost effective. The downside of copper wire was the fact that was low in core strength and would soften in relatively colder climates. Even though this weakness occurred the industry alloyed copper with various materials in order to overcome the
If asked to redo the whole exercise there are quite a few areas which could be improved upon. Our team believed that we could achieve more if the tasks are judicially divided amongst all of us as per individual strengths. However, we should have invested quality time on the integration part where all the individual efforts were merged. Our collective work must have been thoroughly proofread but we forgot to allocate sufficient time for it.
