What is a breakdown current of a 50kva transformer?
I depends on the voltage.
What the BDV stands for the transformer oil?
Blowdown Valves In case of Transformer oil the meaning of BDV is break down voltage. It refers to the one of the tests of the oil.
What is a transformer that increases voltage?
A transformer that increases voltage is a step-up transformer.
What is the breakdown voltages of 100KVA transformer bushing and arcing horns?
The question isn't correct, you have to define the voltage level not the power rating.
What is the main different between the power transformer and voltage transformer?
Voltage Tarnsformer transforms only voltage. While power transformer transforms both voltage and current.
How can transformer oil be used in transformers with voltage rating above its breakdown voltage?
In this circumstance, the clearance between components at different potential must be increased.
What is a breakdown current of a 50kva transformer?
I depends on the voltage.
What is difference between breakdown voltage and dielectric strength of transformer?
The dielectric strenght of a transformer represents the maximum voltage permissible to apply across the transformer insulation i.e. between the transformer winding to another part of the transformer, normally the chassis or another winding and without break-down of the insulation ocurring (e.g. arcing). The breakdown voltage of a transformer represents a voltage that exceeds its dielectric strenght and that causes breakdown e.g. arcing across the insulation.
What are the types of power transformer test?
open circuit & short circuit test, insulation resistance test, turns ratio, efficiency, if it is oil cooled then breakdown voltage of oil, voltage regulation and definitely visual inpection...
Can infinite voltage be given at transformer primary?
no, infinite voltage can't be given to the primary of the transformer....if the secondary is connected to the load, then over voltage will damage the load, if secondary is open circuited, then the infinite voltage can breakdown the transformer internal insulation,
What the BDV stands for the transformer oil?
Blowdown Valves In case of Transformer oil the meaning of BDV is break down voltage. It refers to the one of the tests of the oil.
How high can a transformer be rated?
The limiting feature of a transformer is the thermal breakdown of the insulating varnish on the wire. Once this breaks down, some of the windings will short circuit, which will lead to rapid breakdown of the transformer. For small high voltage transformers, the windings are carefully laid down with insulating foils between adjacent windings so as to limit dielectric breakdown.
What happens when a transformer is operated at no load with high voltage?
It depends on how much voltage you have applied. If you apply rated voltage nothing happens only core losses will be there on the transformer nothing will happen apart from that. If you go on increase the voltage core losses will increase and transformer will get heated up. After attaining the breakdown voltage of insulation, insulation in the primary and secondary will fail and the coils will get short circuited then the coils will burn.
WHAT will happen if you run oil transformer with out oil?
As well as providing a cooling medium, transformer oil is also used to insulate a transformer. As its dielectric strength (how well it insulates) is much higher than air, it means that components within a transformer that are at different potentials can be placed much closer together if they are immersed in oil. So, operating an oil-filled transformer without oil will likely cause insulation breakdown within the transformer.
What is a transformer that increases voltage?
A transformer that increases voltage is a step-up transformer.
What is the breakdown voltages of 100KVA transformer bushing and arcing horns?
The question isn't correct, you have to define the voltage level not the power rating.
What is an oil-insulated transformer?
Di-Electric oil to cool the windings inside the transformer, There is a primary winding(high voltage) and a secondary winding(Lower Voltage), Usually stepping down the voltage to about 170 Volts for residential houses, It about 120 Volt by the time it gets to your panel.
