Will dielectric prevent water from getting in a connection on a transmitter antenna?
The best material to use on these types of connections is a rubber amalgamation tape. This can be purchased at any electrical supply house. After applying the rubber tape overlay it with ordinary electrical tape. The electrical tape has UV protection that will stand up under the sunshine and protect the rubber tape. When the electrical tape starts to look dried out and starts to crack just re install new electrical tape, the rubber tape will be alright and not need to be replaced.
Why npo before paracentesis?
to prevent aspiration to prevent aspiration
Does sound go through acoustic panels?
Yes. Acoustic panels are meant to reduce echoing, not stop sound for passing through. To stop sound from passing through, you need 1 of 3 things: 1. A wall that is heavy. conrete block walls are good for this. You can also use double layers of gypsum wallboard on each side of the wall. 2. Offset wall studs. Your side of the wall is on one set of studs, and the other side of the wall is on an entirely different set of studs. This way, there is no direct path for sound waves to pass through. 3. Mount the wallboard on both sides of the wall on spring clips. The spring clips prevent a direct transfer of sound through hard materials.
When trying death metal growls after a couple minouts your voice gets gurgly from phlem spit in your throat how can you prevent it?
i don't believe you can prevent it... just do it alot and your voice should get used to it... like mine =]
What is the name for a metal cap or band placed on a stick to prevent it from splitting?
ferrule or ferule
Why do secondaries kept short in current transformer?
To prevent the appearance of a dangerously-high secondary voltage across its terminals.
How does a transformer prevent shock?
Transformers don't prevent shock
What are the bushing in the current transformer?
The bushing acts as an insulator to prevent a short circuit. In large distribution transformers, the voltages used are so high that it the wires cannot be allowed to come too close to each other, or too close to the metal casing of the transformer. If they do get too close, then the voltage can actually jump through the air (electrical breakdown), and create a short circuit. The bushings are made longer than they need to be because things like rain, and sharp points on a transformer terminal can make it easier for the voltage to jump through the air.
What is the need of lamination in transformer?
The laminated plates prevent eddy currents from forming and thus creating unwanted magnetic flux which would counter the flux needed to induce the electric current in the secondary coil
Differentiate delta to delta connection of the transformer to delta to Y connection?
In delta to delta there will be no ground on both primary and secondary sides. Leave the primary side but we take care on secondary side. If there any fault occurs on the secondary then there will be unbalanced voltages between the phases results in the flow of current through the secondary windings so only we are using star on the secondary side while having neutral to prevent such a current flow.
To prevent accidental electrical shock most electrical equipment is?
Grounded.
What is the job of an insulator?
Thermal insulator, prevent heat loss and protect human or machine from heat. Electrical insulator, prevent human and machine from electrical hazard and prevent short circuit that would damage electrical appliance.
What is the use for an electrical fuse?
To prevent overloading in case of an electrical fault in the equipment.
Difference between isolation transformer and Scott-T transformer?
The Scott-T transformer was used to run 2-phase equipment from a 3-phase source. Older power distribution systems (and equipment) were 2-phase. An isolation transformer usually has the same input and output voltages (120:120, 240:240, etc) and is used to isolate the source from the load. Isolation transformers are used in medical equipment, for instance, to prevent a patient hooked up to a monitor from being electrocuted during an electrical fault.
Why the stator is not laminated in DC machines?
The stator is not laminated in DC machines because it does not need to be laminated. Lamination is used in AC machines to prevent eddy currents from generating excess power due to the transformer effect of having a one-turn secondary that is short circuited. There is more to it than just the laminations - the laminations are insulated from each other, and interleaved, so that they have poor electrical connection while having good magnetic coupling.
How do you prevent electric shock?
using high quality insulation for all electrical and electrical equipment.
How do you prevent a ground from happening in an electrical circuit?
insulation
