After installation, place the pk42mvdR.dll file in the software installation folder (usually not in the C drive). Then click on CYMGRD inside the installation folder to run the software. If no error message appears, the software is installed correctly. If an error about missing SC32W file appears, copy the contents of the REQUIRED FILE folder to the installation folder. This will resolve the issue. The following modules enable realistic and practical cable studies: Power Cable Ampacity Duct Bank Optimizer Module Multiple Duct Bank Module Short Circuit Rating Real Time Temperature Rating CYMCAP/MDB, Multiple Duct Banks module CYMCAP Software: CYMCAP software is used for precise calculation of the capacity and heat rating of power cables. Its accuracy increases confidence during cable upgrades and new cable designs. It also enhances system reliability and supports proper use of installed equipment. CYMCAP performs thermal capacity and temperature rise calculations for power cable installations. Determining the maximum current that power cables can carry without damaging their electrical properties is crucial for electrical facility design. This software was jointly developed by Ontario Hydro (Hydro One), McMaster University, and CYME International under the Canadian Electricity Association. Selecting the appropriate cable size is one of the most important engineering tasks, often done manually. If the chosen size is smaller than required, cable damage or system malfunction may occur; if larger, despite proper function, economic design considerations are neglected. In most projects, designers calculate cable size based on voltage drop and short circuit criteria, often ignoring thermal sizing. For thermal sizing, especially for MV and HV cables, cable construction and layer specifications must be accurately modeled, and allowable current calculated based on installation environments such as underground, air, tunnels, ducts, trenches, etc. In this course, using the professional cable sizing software CYMCAP, we introduce various cable aspects, steady-state sizing, transient sizing considering current profiles, temperature field estimation around cables, magnetic flux density calculation around cables, induced voltage on shields, optimizing cable arrangement in duct banks, cable impedance matrix calculation, etc., based on IEC60853, IEC 60287, and Neher-McGrath methods.

Control of the temperature and humidity of the server room
The temperature and humidity control devices of the server room are very numerous in Iran, some manufacturers and others are just the product seller, but what is more important is which system at the cost of it really works and the impression does not happen that it was wrong to buy from the beginning. \r\n\r\n1- If the server intelligent control that is purchased is unstable or gives false warnings\r\n2. If the server room intelligent system is purchased, send a warning late or delayed \r\n3. If the intelligent monitoring of the server room that is purchased is abolished in times of danger and cannot be able to send alerts.\r\n4. If the intelligent controller the server room temperature is purchased does not have the quality needed to protect the server room\r\n5. If the intelligent automation of the server room is purchased is provided by a company that has little experience in control and automation.\r\n6. If the intelligent control of the server room is not interior design and we have to spend a lot of time repaired \r\n\r\n[Types of Server Room Sensors] (https://pishrans.com/%25d9%2585%25d9%2582%25d8%25A7%2584%25d8%25A7%25d8%25aaa/174-sever-room-sensorsors)\r\nThe above and other things can cause irreparable problems for the server room manager, so the employer ultimately concludes that the choice is made, but this choice is no longer reversible and cannot offset the damage to the server room or the server room data and cannot retrieve the intelligent control system.\r\nTherefore, the solution to these events is to scrutinize and select the correct and secure intelligent system.\r\n \r\nhttps://pishrans.com/src2-2\r\nResume \r\nhttps://pishrans.com/projects1\r\nPhoto of projects\r\nhttps://pishrans.com/photo-project
