current of the distance protection installation portion fault line are obtained through Fourier transform; according to the operation state of the parallel double-circuit line, single-phase earth fault impedance Z of the parallel double-circuit line is calculated; according to the single-phase earth ...
Since relays measure voltage and current values, the power factor can also be calculated. As a result, apparent (S), real (P) and reactive (Q) power can be derived from current and voltage measurements. The three phase and per phase relationships between the voltage (V), current (I), ...
Before power on the system, using insulation test to verify if it is good to improve system performance. Insulation test is to find manufacturing process problems and equipment fault which can not be found before failure happened.In EU,this test is compulsory,even to civil system.Fea...
This might the business world, this would be analogous to knowing indicate that healthcare is not performing as well as what resources are available and what the support center's education in general; however, healthcare is taking over baseline level of performance is. In regards to resources,...
target equilibrium temperature as a target effective power corresponding to the periodic voltage, wherein the program compares a stored allowable power of the capacitor with the target effective power corresponding to the periodic voltage in order to determine whether or not the capacitor is available....
The GUI 1300 also preferably includes a text area 1314 that includes a description of the currently-selected node in the HS tree, along with available child nodes. For example, if the selected node corresponds to HS code “8524.99.10,” and the current country is Canada, the description may...
three phase to earth. By convention, the “Peak” is the maximum current value achieved in the early asymmetrical period and it is at this point that the highest instantaneous force between the cables occurs.Where the system peak fault current and the cable diameter are known, BS EN 61914:...
Before executing the transaction, a check is made of the remaining On Demand environment to determine if the environment has sufficient available capacity for processing the transaction. This environment capacity consists of such things as but not limited to network bandwidth, processor memory, storage...
For the fourth and last part of landing, the pilots have the option to either use the braking system manually or use the autobrakes in one of the four available settings, 1, 2, 3, or MAX. The static calculations have to be done based on an expected behavior, so there is an input ...
An unforeseen error is then a physical state that does not correspond to the current active control system state. Moreover, the actions required when correcting the error may force an operator to further corrupt the physical state during the error correction phase, such as moving a robot to a...
