Which is the minimum absolute error tolerance for quadgk?
For pure relative error control use ‘RelTol’ > 0 and ‘AbsTol’ = 0. Except when using pure absolute error control, the minimum relative tolerance is ‘RelTol’ >= 100*eps (class (q)). Example: quadgk (fun,a,b,’AbsTol’,1e-12) sets the absolute error tolerance to approximately 12 decimal places of accuracy.
Why do I have a dipped headlight fault?
IF YOU HAVE A “DIPPED HEADLIGHT” FAULT ON YOUR DASH SCREEN… This is either because you have a faulty ballast (different issue entirely, but will require these steps after replacement), or your adaptation/adjustment as not been set.
How does adaptive meshing help reduce global error?
Adaptive mesh refinement settings to reduce the global error in the model. Relevant settings are highlighted. The result of this adaptive mesh refinement is shown below. Note how the mesh is quite uniformly refined throughout the domain. The stress field is clearly smoother than on our original mesh.
Why does differential protection have a higher sensitivity?
Another attribute of differential protection is that it has generally higher sensitivity relative to the other three types of fault detection elements because it responds to the difference current in the zone of protection. It does not need reduced sensitivity to accommodate load flow, natural system unbalances, or out-of-zone faults.
What are the symptoms of a bad front differential?
There are a few noticeable signs that will present themselves if your front and/or rear differentials start to wear out or get damaged. Here are the most common symptoms that you can expect to happen if your differential goes bad. Whining noises are one of the most common and noticeable symptoms of a bad differential.
How is percentage restrained differential related to false differential?
high levels of current are flowing and false differential current due to current transformer (CT) saturation is more likely. The percentage restraint characteristic operates on the ratio of operate-to-restraint current in the zone of protection. The operate quantity is universally defined as the magnitude of the
How does differential protection work in a power system?
Differential protection works on Kirchoff’s current law that states that the currents flowing into a node of the power system must sum to zero, as shown in Fig. 1. The differential zone is defined by the location of current transformers (CTs) on the primary circuits around a power system bus or apparatus. If the currents sum to
