What is different between feeder breaker and motor breaker?
You have to be careful with terms in the electrical field, Example: Main Feeder Circuits will feed a Transformer for distribution and each of those main circuits might feed numbeous Motor control centers. However each of those circuits could be called a main feeder for the motor control center. Confusing. We have High Voltage Transmittion tansformered down for Distribution. So normally a Feeder Breaker will feed Main circuits that will be used for distribution. Example Your home panel will have a main feeder circuit to the whole panel and distribution breakers to you home.
How many amps do you need to supply a 150kva transformer to get 118amps 480 volts?
Rephrase your question, as it doesn't make any sense. If the primary side of the transformer is 480 volts 3 phase, this transformer can be supplied from a breaker as big as 180 amps. If 480 volts 3 phase is your secondary then you can supply up to 180 amps to your loads.
Why supply circuit breaker should be 4poles?
Because it has neutral with 3 phases. A supply circuit breaker is used on the lv side of the transformer to protect the equipment connecting to it.
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.
The primary winding in a transformer is connected to the what?
The primary winding of a transformer is connected to the supply, while the secondary winding is connected to the load.
What happen if the secondary side of step down transformer supply a bigger voltage?
it would be called a step up transformer
Why keep a voltage transformer secondary open?
it is keep open so as to supply voltage to the loadAnswerThe secondary winding of a transformer is NOT necessarily kept open, unless you want to disconnect its load.
What are possible uses of a single phase 30VA transformer?
To continuously supply a load of up to 30-V.A at the rated secondary voltage of the transformer.
What are the primary winding and secondary winding of a transformer?
The primary winding is the winding connected to the supply, while the secondary winding is the winding connected to the load. The terms, 'primary' and 'secondary' are unrelated to voltage levels.
What is stepup transformer?
A step-up transformer produces a voltage across its secondary winding which is higher than its primary winding. The secondary winding is connected to the load, while the primary winding is connected to the supply.
What happens if a dc supply is given to a transformer under no load?
when dc supply is given to transformer at primary winding , the output at secondary winding will be zero.Because to induce voltage ,countnie changing flux is required ,that can not be obtained from dc supply...........
What is winding transformer?
A winding is the name given each of the coils wound around the transformer's core. A basic transformer has two windings, termed the primary winding (connected to the supply) and the secondary winding (connected to the load).
