What is directional mutation?
one which changes the characteristics of an organism so it moves in a direction. Like if stin colour mutated so it was darker the mutation was directional to make skin colour darker not lighter.
What is a directional group?
A directional group is a term used in geology to describe a group of rocks that have a common orientation or alignment. This alignment is typically caused by tectonic forces or geological processes that have affected the rocks over time. Directional groups are important for understanding the history of deformation in a region.
What is used in an electrical circuit to prevent a short current?
A Fuse or a circuit breaker can be used to protect an electric circuit from over loads. A surge arrestor / over voltage relay can be provided for voltage protection An ELCB/ Earth fault Relay may be provided for earth fault protection. Electrix Chennai, India.
How do directional selections and stabilizing selection differ and do they tend to increase or decrease diversity?
Well, Directional Selections and Stabilizing selections are different because in Directional Selection, the frequency of a particular trait moves in one direction in a range, while in Stabilizing Selection, the distribution becomes narrower, tending to "stabilize" the average by increasing the proportion of similar individual. Also, I'm not sure about this but I think the continued gene flow tends to decrease the diversity between populations.
Which form of natural selection is shown on the chart stabilizing disruptive or directional?
To determine which form of natural selection is represented on the chart, it would be essential to examine the characteristics of the population depicted. Stabilizing selection favors average traits, disruptive selection favors extreme traits, and directional selection favors one extreme over the other. Without seeing the chart, it’s impossible to specify which type is shown, but you can identify the type by looking for these patterns in trait distribution.
Non-directional over current relay?
The synchronous generator when act as a motor that relay is operated. or reverse power relay is acted. mainly it sence thet direction of power flow direction
What is the difference between an earth fault relay and an over current relay?
earth fault relay is also a type of over current relay but the set value of current or relay sensing current is much less than the maximum load current.in over current relay relay sensing current ise than maximum load current mor
What the three types of over current protection relay and describe the principles of operation?
over current protection relay
Is a current relay same as potential relay?
current relay are using for over current low state & high state.but potential relay are related to voltage.
How does an over current relay work?
An over current relay will operate when current exceeds its design rating. This application is intended protect loads or circuits from excessive current.
Over current relay?
in electrical circuit current will increase specific level (full load current).its call over current
What is the difference between directional and non directional over current protection?
The directional part. Directional relays will operate for events "in front of" them, but will not operate for events "behind" them. Typically directional relays are used in non radial situations such as on the bulk electric system. Non-directional overcurrents are commonly used on radial lines.
What is ocr efr uvr referred to in air blast circuit breaker?
ocr-over current relay(senses the over current in the circuits) efr-earth fault relay uvr-under voltage relay
What are time delay relay characteristics?
Time delay protective relays used in the power industry can be time over current or voltage, or definite time over / under voltage / over current.Definite time type relays use an over / under voltage / current element that picks up when voltage / current reach a specified level. When this picks up, a timer is started. If current / voltage stays above / below the pickup value for long enough to allow the timer to expire, the relay trip contacts are closed.Time over current elements use an inverse time - current curve to define speed of operation, so the more current is present, the faster the relay will operate.
What is instantaneous over current relay?
Instantaneous over current relay, which operates very fast with no intentional time delay and the operating time of these relay can be as low as 0.01sec . These relay operates only when the impedance between the relay and the source zsis very small compared to the impedance to the impedance of the protected section zl .
How does time inverse over current relay work?
Over Current (Inverse Time) Over current relay function monitors the general balanced overloading and has current/time settings. This is determined by the overall protective discrimination scheme. There advantage over definite time relays is that they can have much shorter tripping times can be obtained without any risk to the protection selection process. These are classified in accordance with there characteristic curves, this indicates the speed of the operation. Based on this they are defined as being inverse, very inverse or extremely inverse. The typical settings for these relays are 0.7-2In (normal or rated generator current) in 1-10 second. Inducing a calibrated test current through the normal load current tests this relay.
