What else can I help you with?
Can you load a transformer by a pure capacitive load?
No
What is the significant relationship of the no load loss in excitation current test in transformer?
The no load losses are the losses caused by energizing the transformer. These are constant losses, regardless of loading. This in effect tells you the efficiency of the transformer. (Power in) - (no load losses) = (Power out)
What is non-inductive load?
non- inductive load is without motor and transformer loads are non-inductive load, purely resistive are capacitive loads phase angle is unity are leading PF A non-inductive load is a load whose current does not change instantaneously.
Why are distribution transformers frequently designed to develop maximum efficiency at loads that are somewhat lower than rated value?
It is always desirable to run any equipment or device at maximum efficiency for that matter, not only the power transformer. Power transformer maximum efficiency occurs when copper loss is equal to iron loss. (or no load loss equals to load loss). This does not necessariliy mean that maximum efficiency occurs at maximum or full load. Generally the maximum efficiency occurs at relatively less than full load of the transformer.
Is tube light capacitive load?
no
Can you load a transformer by a pure capacitive load?
No
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.
When is the efficiency maximum in a transformer?
the efficiency is maximum in a transformer when no load loss is equal to load loss.
What is the percentage load at which maximum efficiency occurs for the single phase transformer?
For a single-phase transformer, maximum efficiency typically occurs at around 50-70% of the rated load. Operating the transformer at this load range minimizes losses and improves efficiency. Going below or above this range can decrease efficiency and increase losses in the transformer.
Would a computer be considered a capacitive load?
No because the very first component in the power supply is a transformer, which makes for it being an inductive load.
Does low load in transformer lead to low power factor?
Power factor is determined by the nature (resistive, inductive, capacitive) of a load, not whether it is a low load or a high load.
When is a transformer closet to unity power factor?
When it supplies a resistive load.
Why the load voltage increases when the load used is capacitive?
capacitive reaction
What is the significant relationship of the no load loss in excitation current test in transformer?
The no load losses are the losses caused by energizing the transformer. These are constant losses, regardless of loading. This in effect tells you the efficiency of the transformer. (Power in) - (no load losses) = (Power out)
When a two winding transformer is connected as an autotransformer its efficiency under full load is?
remain same
What is non-inductive load?
non- inductive load is without motor and transformer loads are non-inductive load, purely resistive are capacitive loads phase angle is unity are leading PF A non-inductive load is a load whose current does not change instantaneously.
