Can HT coil of a distribution transformer damaged due to load on LT coil?

Yes. For any problem or short circuit on LT side there are lot of chances for HT winding to get affected.
Usaually the weakest point gets affected, it may be tap changer or the HV Windings.

A coil of wire with a current is called a?
A coil of current carrying wire wrapped around an iron core, with at least two taps (one including the entire winding, and one including only part of the winding) is a transformer, or more specifically an auto transformer.
Why there is an induced current in a coil when a bar magnet is thrust into the coil?
photons are trapped in the magnetic field when the photon hits the electron of the copper coil the photon take the spot of the electron , its free to move.Answer2: The induced current is a consequence of the conservation of the magnetic field.AnswerCurrent isn't induced into a coil -it's voltagethat is induced. Any current flows as a consequence of this induced voltage only if there is a load connected to the coil.
What is a tansformer?
The generator transformer is the first essential component for energy transmission, allowing energy supplied by the generator to be transferred to the network at the required voltage.The generator transformer is the first essential component for energy transmission, allowing energy supplied by the generator to be transferred to the network at the required voltage.This is a type of Power Transformer where the LV winding is connected to the generator through the bus duct and HV winding to the transmission system. In addition to the features of Power Transformer, our Generator Transformer is designed to withstand over voltage caused by sudden load throw off from the generator. It is built as a single or three phase unit and located in power stations.
Why there is an induce current in a coil when a coil is compressed in a magnetic field?
compressing a coil in a magnetic field means that there is a relative movement of the the said coil existing in a magnetic field, hence current will be induced. induction law.Another Answer'Current' is not induced into a coil. It's voltagethat's induced; if the coil forms a closed loop, then current will flow; if there is no closed loop, then no current will flow.The induced voltage results from either a change in current through the coil, or from the relative movement between the coil and an external magnetic field.
Spring under twisting moment?
spring are subjected to torque or twisting moment when they subjected to load.As the load is applied both tensile or compressive the coil is subjected to twisting moment which is max at the centre and min at the circumference just opposite to the shaft.
When current in primary coil decreases current in the secondary coil also decreases?
It is reverse. when load current in the secondary changes the primary current also changes directly. Load current is dependent on the load. I am assuming that the question is related to a normal distribution transformer.
When secondary coil is open there is no current in the primary coil WHY?
I am assuming the question is about the power / distribution transformer and not the current transformer. The primary current is a function of load connected on secondary. With the open secondary, there is no load, no current, it is open circuit. Hence no primary current. However there is always some small amount of no load current in the primary winding.
What is the secondry side of distibution transformer?
There's very little point in having a distribution transformer if its secondary winding isn't connected to a load! So, to answer your question, a 'secondary system' (by which you, presumably, mean 'load'), isn't 'essential' to a distribution transformer, it could just sit there doing nothing!
How do you solve low voltage in electricity problems?
low voltage problem may arise due to unbalancing of distribution transformer in your area. please ask your electricity provider to balance load on distribution transformer.
What happens when transformer is overloaded?
it trips the breakerAnswerThe transformer will overheat. But this is not necessarily a bad thing, providing the transformer is also allowed to operated below load, during which time it can then cool down. This cycle of overload/below load operation is quite usual for distribution transformers.
Is a transformer load inductive or capacitive?
A transformer is fundamentally a set of coils; therefore, a transformer is an inductive load. However, by "transformer load", you seem to mean "the load that is connected to a transformer". Whether that load is inductive or capacitive depends mostly on what is hooked up to the transformer.
What Device used to select amount of voltage in primary coil of step up transformer?
There is no selective device to determine the amount of voltage. A transformer is selected by the voltage available at the site for the primary and the load on the secondary side of the transformer.
Difference between off load transformer and on load transformer?
Hope this helpsAn "OFF-Load tap transformer" can only have it's tap adjusted when it is De-energized,while the "On-Load tap transformer" can adjust its tap under load conditions.Kind RegardsHammad KhanUniversity of Western AustraliaAnswerAn 'off load' transformer is one whose secondary is open circuited, and not supplying a load. An 'on load' (not 'load') transformer is one that is connected to a load.
Why on load or off load tap changer is always connected in the primary side of a power or distribution transformer. And why distribution and power transformer are rated MVA?
The size of any switch depends on current it carries. Your statement is true for step down transformers. The primary is HV hence less current, so the tap changer is on primary side.
How do you load a transformer?
Anything that draws energy from a supply is a load. So you 'load' a transformer by attaching a lamp, a motor, etc., to the transformer's secondary windings.
What is the full load loss of a 630 kilo volt ampere and primary voltage is 11000 VOLT and secondary voltage is 440 VOLT of a distribution transformer?
That type of transformer normally has about 99% efficiency so the full-load loss would be 1% or 6 kW.
Can i Over load an oil filled transformer?
Any transformer can be overloaded by applying a load above the capacity rating of the transformer.
