What does common coupling mean?
Point of Common Coupling means the point where the electrical conductors of the distribution system are connected to the customer’s conductors and where any transfer of electric power between the customer and the distribution system takes place. Typically, this is the customer side of the Public Utility’s meter.
What is coupling in a relationship?
1. There exists a coupling relationship between objects a and b if object a (or b ) has an influence on object b (or a ) or they interact with each other.
What is the meaning and purpose of coupling?
A coupling is a device used to connect two shafts together at their ends for the purpose of transmitting power. The primary purpose of couplings is to join two pieces of rotating equipment while permitting some degree of misalignment or end movement or both.
How do you use coupling in a sentence?
Coupling sentence example. There were no coupling rods. In these the central bar which connects the two end links has screw threads cut upon it,;and by means of a lever can be turned so as either to shorten the coupling and bring the vehicles together till their buffers .
What is modularity explain cohesion and coupling in detail?
Coupling shows the relationships between modules. Cohesion shows the relationship within the module. Coupling shows the relative independence between the modules. Cohesion shows the module’s relative functional strength. While creating, you should aim for low coupling, i.e., dependency among modules should be less.
What is communicational cohesion?
Communicational cohesion is when parts of a module are grouped because they operate on the same data (e.g., a module which operates on the same record of information).
What is conscious coupling?
Reading Time: 5 minutes. My definition of conscious coupling means choosing to enter into and commit to a relationship from a space of complete openness and vulnerability with a goal of safely co-creating a fulfilling life together.
What is the purpose of a coupling?
The basic function of all couplings is to transmit power, accommodate misalignment and compensate for axial movement (end movement of shafts). Sometimes, a coupling is asked to absorb shock or vibration. Selecting the right coupling depends on four basic conditions of shaft misalignment or movement.
What coupling means?
Definition of coupling 1 : the act of bringing or coming together : pairing specifically : sexual union. 2 : a device that serves to connect the ends of adjacent parts or objects. 3 : the joining of or the part of the body that joins the hindquarters to the forequarters of a quadruped.
What do you mean by coupling in sad?
Coupling: Coupling is the measure of the degree of interdependence between the modules. A good software will have low coupling. Data Coupling: If the dependency between the modules is based on the fact that they communicate by passing only data, then the modules are said to be data coupled.
What is the relationship between coupling and cohesion?
Coupling and cohesion are terms which occur together very frequently. Coupling refers to the interdependencies between modules, while cohesion describes how related the functions within a single module are.
Why is the point of common coupling important?
Point of Common Coupling (PCC) In other words, the PCC is the point on the network, nearest to the generator, at which other customers are, or could be, connected. Thus, the exact location of the PCC can depend on who owns the line between the generator and the rest of the network. The importance of the PCC is that it is the point on…
How does harmonic current affect point of common coupling?
Figure 2.18. Harmonic current from customer 1 to point of common coupling (PCC). The distorted voltage at the PCC affects other customers connected to the same PCC by supplying a distorted voltage supply, i.e., distorted voltage is supplied to customer 2 connected to the same PCC.
Which is the point of common coupling in microgrids?
Points of common coupling of Microgrids #1, #2, and #3 are PCC1, PCC2, and PCC3, respectively. Points of common coupling are configured with the same grid connection interface devices, which are designed in low voltage switch cabinets. Refer to Figs. 6.4 and 6.6 for details.
