What does it mean when a guy says feed me?
What does it mean when a guy says feed me?
An expression that someone says when they want food. It is rude to say to a guest. example: I am hungry, feed me! See a translation.
What makes someone a feeder?
Technically, Lisa displayed characteristics of both “feeder” (those who become sexually aroused by feeding their partners and encouraging them to gain weight, sometimes to a state of immobility) and “feedee” (individuals who are erotically aroused by their own weight gain or being forced to eat).
What is the difference between feeder and busbar?
feeder means power transmission at one point to another point. Busbar is like a node where different power system elements are connected like Alternators, Power Transformers etc.. while Feeder is used to feed electrical power from Busbar to distributors… we can connect more than one feeder to a Busbar.
What is busbar trunking?
Busbar Trunking System is the is a system of distributing electric power using copper or aluminium busbar with suitable enclosures and good amount of protection to prevent the cables from getting damaged due to foreign bodies. The system of cooling is much better than traditional cabling system.
When would you use a busbar?
Where are busbars used?
- Busbar systems are used to safely implement three-phase power distribution systems, often in large environments.
- They can also be used as housing for expandable track lighting which runs from one single power supply.
Why is it called a busbar?
The term busbar is derived from the Latin word omnibus, which translates into English as “for all”, indicating that a busbar carries all of the currents in a particular system.
What happens if you touch a busbar?
so the effect of touching a busbar are the same as that of touching a conductor. But you touch busbar while standing the ground, there is a contact between the line to ground and there will create a L-G fault. you will receive a heavy electric shock before the CB trip and it is enough to cause death.
What is feeder in substation?
Feeder transmits power from Generating station or substation to the distribution points. They are similar to distributors except the fact that there is no intermediate tapping done and hence the current flow remains same at the sending as well as the receiving end.
Which busbar scheme offers the lowest cost?
Which of the following bus-bar schemes has the lowest cost?
- A. Ring bus-bar scheme.
- Single bus-bar scheme.
- Breaker and a half scheme.
- Main and transfer scheme.
How is the bus bar rated?
Other organizations, including the Institute of Electrical and Electronics Engineers (IEEE), currently offer guidance. The IEEE states a busbar should be rated at the highest amperage passing through any section of the busbar, with a maximum of a 50° C rise in temperature from an ambient temperature of 50° C.
Which of the following bus bar arrangement is more reliable and flexible?
Double Bus Double Breaker Arrangement It does not require any additional equipment like bus coupler and switch. This type of arrangement provides the maximum reliability and flexibility in the supply. Because the fault and maintenance would not disturb their continuity.
Which of the following bus bar configuration have least reliability?
A single bus arrangement has the lowest reliability. Failure of a circuit breaker or a bus fault causes loss of the entire substation. Maintenance switching can complicate and disable some of the protective relay scheme and overall relay coordination.
Which distribution system is more reliable?
A _________ distribution system is more reliable than the ______ distribution system. Explanation: A parallel distribution system has two end feeding and an alternative of parallel line, so in case there is a fault, the isolator can isolate the faulty part and let the healthy system operate.
What is a breaker and a half scheme?
The breaker-and-a-half configuration, typically used at extra-high-voltage (EHV) stations, consists of two buses, each normally energized. The breaker-and-a-half configuration provides for circuit breaker maintenance, since any breaker can be removed from service and isolated without interrupting any circuit.
Which protection system is used for busbar?
Current Differential Protection. The scheme of busbar protection, involves, Kirchoff’s current law, which states that, total current entering an electrical node is exactly equal to total current leaving the node. Hence, total current entering into a bus section is equal to total current leaving the bus section.
Which relay is used for feeder?
Buchholz relay
What is the difference between busbar protection and LBB protection?
Fault occurs and say one of the Protection Relay Operates. Master Trip Relay Operates. If the Fault is cleared within 200ms, the LBB Scheme is Reset, but if the Fault is not cleared, LBB Operates. When the LBB Operates, it Trips, all the feeders on the concerned Bus with the help of Busbar Tripping Circuit.
Which is the pilotless protection method for feeder line?
Differential protection
Which relay is used at the far end of the radial feeder?
In radial feeder, the power flows in one direction only, which is from source to load. This type of feeders can easily be protected by using either definite time relays or inverse time relays.
What is meant by time graded protection?
This is a scheme in which the time setting of relays is so consecutive that in the event of a fault, the smallest possible part of the system is isolated.
What is current relay grading?
INTRODUCTION: By using the given data firstly fuse A, fuse C, relay B and relay J characteristics are plotted by taking 3.3kv as the base voltage then the grading is done with the upstream relays. For over-current relays, C.T. winding resistance=0.05Ω and one way lead resistance=0.1Ω.
What is current graded system?
In this scheme of Time Graded Overcurrent Protection, time discrimination is incorporated. In other words, the time setting of relays is so graded that in the event of fault, the smallest possible part of the system is isolated. We shall discuss a few important cases.
Why is an electrical network graded?
Protection Grading is an essential part of the electrical network, ensuring discrimination and selectivity of downstream faults.
Why is relay coordination needed?
Relay coordination is an important aspect in the protection system design as coordination schemes must guarantee fast, selective, and reliable relay operation to isolate the power system faulted sections. Thus the relay coordination problem is formulated, for a real time distribution system is simulated using ETAP.
How do you relay coordination?
Relay co-ordination can be done by selecting proper plug setting and time multiplication setting of the relay, considering maximum fault current at the relay location. After selecting the plug setting and time multiplier setting, the co-ordination can be checked graphically.
How do you calculate the operating time of a relay?
Operating Time of Relay for Long Time Inverse Curve (t) =120 / ((PSM) -1). Operating Time of Relay for Normal Inverse Curve (t) =0.14 / ((PSM) 0.02 -1). Operating Time of Previous upstream Relay = Actual operating Time of Relay+ Total Grading Time.
