What is the significance of vector-grouping in Power Transformers?
Vector group of Transformer: a.)The three stage transformer windings can be joined a few ways. In light of the windings' association, the vector gathering of the transformer is resolved. b.)The transformer vector gathering is shown on the Name Plate of transformer by the producer. c.)The vector gathering shows the stage contrast between the essential and auxiliary sides, acquainted due with that specific setup of transformer windings association. d.)The Determination of vector gathering of transformers is imperative before uniting two or more transformers in parallel. On the off chance that two transformers of diverse vector gatherings are associated in parallel then stage distinction exist between the optional of the transformers and huge coursing current streams between the two transformers which is extremely impeding.
Write a program in C language to find out the dot product of two vector quantities in Cartesian?
#include <stdio.h> #include <ctype.h> #define n[] int main() { int n, result , answer; int a[n], b[n]; printf("Enter number of terms you would like to use :"); scanf("%d", &n); printf("Enter first vector:\n"); scanf("%d", &a[n]); printf("Enter second vector:\n"); scanf("%d", &b[n]); printf("The dot product is \n" ); return 0; }
How do you write a c plus plus program to sort a vector of strings using MSD radix sort?
The standard library sort algorithm automatically uses MSD radix to sort strings: std::vector<std::string> vs = {"a", "b", "c" "d", "ab"}; std::sort(vs.begin(), vs.end()); After sorting, the order will be: {"a", "ab", "b", "c", "d"}
MOV D IN Microprocessor means?
MOV D,reg means: move content of the specified register (or M=memory addressed with HL) into register D
Is there any priority between logical and logical or operators in c language?
Yes, a&b|c&d means (a&b)|(c&d), just like a&&bc&&d means (a&&b)(c&&d)
The figure shows two vector B and C along with magnitude and direction . D is given by D =B -C. What is the magnitude of vector of D What angle does vector D make with the +x-axis?
Nothing
Prove that if magnitude of vector A is constant then d by dt of vector A is perpendicular to vector A.?
That is not even true!
What is the direction of the vector product when finding the direction of the vector product a x d?
The direction of the vector product a x d is perpendicular to both vectors a and d, following the right-hand rule.
What has the author C D Collinson written?
C. D. Collinson has written: 'Introductory vector analysis' -- subject(s): Vector analysis
How do you find a normal vector?
A normal vector is a vector that is perpendicular or orthogonal to another vector. That means the angle between them is 90 degrees which also means their dot product if zero. I will denote (a,b) to mean the vector from (0,0) to (a,b) So let' look at the case of a vector in R2 first. To make it general, call the vector, V=(a,b) and to find a vector perpendicular to v, i.e a normal vector, which we call (c,d) we need ac+bd=0 So say (a,b)=(1,0), then (c,d) could equal (0,1) since their dot product is 0 Now say (a,b)=(1,1) we need c=-d so there are an infinite number of vectors that work, say (2,-2) In fact when we had (1,0) we could have pick the vector (0,100) and it is also normal So there is always an infinite number of vectors normal to any other vector. We use the term normal because the vector is perpendicular to a surface. so now we could find a vector in Rn normal to any other. There is another way to do this using the cross product. Given two vectors in a plane, their cross product is a vector normal to that plane. Which one to use? Depends on the context and sometimes both can be used!
Which of the vectors in the graph below is the negative of the vector ?
D
Why is identification of the vector group of transformer important?
Vector group means it defines the primary & secondary side connection type of the transformer.For example DY says D for the delta connections (windings connected between two phases) & Y for the star connections (windings connected between two phases). That's why identification of the vector group of transformer is important.AnswerVector groups specify whether two or more three-phase transformers can be paralleled with each other. In order to do so, their angular displacements must be the same. Transformer connections listed in the Vector Group tables, categorise transformer connections in terms of their angular displacements.
Is power scalar quantity?
Power can be scalar or vector, e.g d/dt torque = vector power; d/dt mcV = mcA a vector power.

Where is the area vector for a sphere?
R^2sin(theta)d(theta)d(phi)(r-hat)
What is the meaning of DY 11 on a transformer nameplate?
there is no specification of Dy11.. it will be Dyn11.. it is the vector group of the transformer. capital d means primary winding is delta secondary winding is star(y) and the secondary current lags voltage by 30degree this angle when shown in clock will be looking like 11 o clock
What is vector group of power transformer?
Hi first of all Vector group used to determine the PHASE shift of the TRANSFORMER as well as the PRIMARY and SECONDARY connection information. Let taken an example:- YNyn0d1 It means CAPITAL LETTERS indicates the primary side of winding detail's small letters for secondary side detail's DELTA CONNECTION Symbol D OR d is used and connection WYE used Y OR y for PRIMARY and SECONDARY. If WYE connection is their neutral always come so we used suffix N OR n. Now check PHASE angle Difference (PHASE ANGLE) see the last NUMERIC VALUE give correct information. Suppose we connect/compare two TRANSFORMER we first see its VECTOR GROUP if they matched then we do move to any connection. If any quarries fill-free to ask ajay.sahu099@gmail.com
