In addition, digital technology provides a transient monitor function that enables the BE1 CDS2. CT saturation to ride through the condition to further enhance security from misoperation caused by poorly performing CTs. This is illustrated in Figure 1 3. BE1 CDS2. 40 Solution The BE1 CDS2. CT ratio and voltage bases by converting the currents to per unit quantities on a common base. It can be seen that the primary currents flowing into the zone of protection when tap is adjusted for magnitude mismatch still do not sum to zero as shown in Figure 1 4, Illustrations B and C. Ashampoo Winoptimizer 10 License Key. BE1 CDS2. 40 General Information 9. Rev F. 1. 80 out of phase with each other. They will always sum to zero after tap adjust for magnitude mismatch under all conditions of balance or unbalance except when there is a fault inside the zone of protection. Rev F BE1 CDS2. 40 General Information 1 1. CT performance calculation. The BE1 CDS2. 40 relays support the traditional solution so that they may be used in retrofitmodernization projects. However, in a numerical relay, it is possible to connect all of the CTs in wye as shown in Figure 1 6 so that the drawbacks mentioned above are not a consideration. NOTE The BE1 CDS2. It is not possible to reliably determine the phase compensation settings based simply upon phase angle shift information because the phase shift from high to low side is dependent upon the phase sequence of the power system phasors. CT delta just as they circulate in the delta of the power transformer on the delta side. The BE1 CDS2. 40 selects the proper phase shift compensation settings to not only provide the correct phase shift but also to block zero sequence currents as appropriate. This application is greatly simplified with the BE1 CDS2. The user can connect all CTs in wye and specify that the delta transformer winding has a ground source. The BE1 CDS2. 40 will apply delta compensation to the wye winding to obtain phase shift and zero sequence compensation for that current input. Finally, the can compensate to maintain accuracy at off nominal frequency. The BE1 CDS2. 40 uses frequency tracking to adjust the sampling interval to maintain full accuracy across a wide frequency range so that it is both secure and dependable in all applications. For example, tripping of important transformers during a disturbance that causes the system to go unstable can have a catastrophic affect on an already over stressed power system.

Recovering VMware snapshot after parent changed drive activatedarchive. UPDATE 2. 10. 52. Ive been alerted to the ridiculous amount of comment spam this page has gotten apologies to those who were further spammed by the email notifications. I have therefore disabled the email and commenting features, and all future comments will be moderated. Damn spammers have to ruin everything, grrrr. Scroll down to the problem or solution section below if you want to cut to the chase. I upgraded my Kubuntu installation to Gutsy today of course, it wasnt as smooth as it shouldve been. First I had to work out how to do it the instructions were brief, screenshots confusing, and the process just didnt feel natural. The version upgrade button only appears after you have satisfied certain conditions, conditions that you dont know. It just magically appears when it wants to, after pressing a special sequence of buttons. Then the distribution upgrade process crashed, packages wont install. Ended up working after a few tries. For some stupid reason, they still havent fixed the failed to set xfermode bug that heaps of people have encountered and really cripples the system because the system doesnt boot at all. In fact, it removes the fix for it too adding irqpoll to the end of the kernel line for the appropriate entry in bootgrubmenu. Plus they introduced a new bug by adding tablet settings into etcX1. And did I mention that the network connection is flaky and standbyhibernate still doesnt workLinux is still Linux it seems. Anyway, it all worked out in the end after some googling so I went to install VMware Server on it so I could run my virtual machines on it as well as in Windows. There is no package install available for it, so follow the instructions here, however, use this patch instead. Once all that was working, I ran the VMware Console, about to run my Windows Server 2. Standard Edition virtual machine, when I thought, hmm., I dont want this VMware instance fudging with the Windows VMware instance, so Ill create a new virtual machine, and link it to the existing virtual hard disk. Problem. All sounded cool, until I accidentally linked to the base parent hard disk, and not the latest snapshot. So once I booted it, not only did I not have the latest changes, but when I re linked it to the latest snapshot, it wouldnt boot anymore. Instead I got the error message, Cannot open the disk. Reason The parent virtual disk has been modified since the child was created. Did I mention that the virtual machine housed the test instance for this website, including the changes I had been working on all weekend, and I had no other backupAfter a few minutes of cursing and swearing, banging on tables, wondering wtf I had done, and pondering redoing all those changes again, I did what every self respecting nerd does when theyre stuck turn to google. Solution. I found these links Here is my solution, which is basically a rewrite of the process in the last link above, with a few more details. I used Linux to do the recovery, mainly because it had commands that I needed. I assume you have some Linux command line knowledge, as all this will be performed in the terminal. Make a copy of the virtual machine folder in case you screw up. Look at the size of the snapshot virtual hard disk. If it is more than 2. GB and youre running a 3. OS, or it is more than the amount of memory that you have available, the following method will probably not work. Youre welcome to try though. The virtual hard disk files all end in. The snapshot one has xxxxxx on the end of the file name, indicating the snapshot number. For example, if my virtual machine was called Windows Server 2. Standard Edition, my base parent virtual disk will be named Windows Server 2. Standard Edition. Windows Server 2. Standard Edition 0. Find out the CID of the base parent virtual hard disk. Because this virtual hard disk will most likely be larger than 2. GB, you wont be able to open it in nano, vi etc. As we only need to read from it, we can use a linux command to print out only the first 2. Replace vmdk path with the path to the base parent virtual hard disk file, e. Virtual MachinesWindows Server 2. Standard EditionWindows Server 2. Standard Edition. The CID is the 8 character random string on the line starting with CID. Write this down somewhere. Now open up the snapshot virtual hard disk in a text editor, and change the parent. CID not CID to the CID you recorded in the previous step. Then save. You can use nano, vi or some other Linux editor, e. Make sure to sudo the command, and also be patient it could take a few minutes, during which the console may remain black it is loading. I chose to do this in Windows instead, using Editpad Lite which is amazingly fast. Thats it, your virtual machine should now start up again. Further explanation. If youre interested, heres a deeper look into what you just did. At the beginning of each vmdk file is a disk descriptor section, which contains the properties of that virtual hard disk in text. The CID is a random unique identifier that identifies a particular state of the virtual disk each time a change is made to the virtual hard disk, the CID changes. In normal operation, the CID property of the base parent virtual hard disk is synced with the parent. CID property of the snapshot virtual hard disk to show that the two files work together. The snapshot has to work with the base parent to be useful, as it only contains the differences from the base parent virtual hard disk. It is important to note that it is the snapshots parent. CID property that is synced with the base parents CID property, not just the two CID properties in the virtual hard disks the two virtual hard disks are in a parent child relationship. When you startup the base parent virtual hard disk on its own however, changes are made to that virtual hard disk without being in sync with the snapshot, so the CIDs no longer match. And when the CIDs no longer match, VMware complains because the snapshot is out of sync and the changes in the snapshot may not apply properly to the base parent anymore, possibly resulting in data corruption. By forcing the CIDs to match again, you effectively trick VMware into thinking it was never out of sync. Depending on how complex your virtual machine is though, it may be worth recreating your virtual machine after recovering your data because it wont be known where the corruption is, if any. If you did anything to the base parent virtual hard disk before realising and shutting down, e. Tagged with. driveactivatedrecoveryvirtual machinesvmwarepublished 6th November 2.
