What is the Line Voltage and Phase Voltage of the Transformer?
The transformer such asOil Immersed Transformeris a kind of voltage that can stabilize the voltage in the circuit and ensure the stability of the voltage and current in the circuit. For the transformer, it is a kind of electric equipment, which plays a huge role in various circuits and various kinds of circuits. A variety of advantages. Transformers have their own voltage and current. There are two kinds of transformers on the voltage, one is the line voltage and the phase voltage. They are two different voltages in a transformer. They are related and different. So what is the relationship between them?
The line voltage is the phase voltage of 3 times the root number, which is the voltage between the hot lines.
The phase voltage is the voltage between each phase and the neutral line. It is the voltage between each live line and the neutral line.
The line voltage refers to the voltage from the lead line of theThree Phase Transformer. The phase current refers to the current flowing through a phase coil of the three-phase equipment, and the phase voltage is the voltage applied to a separate set of coils. The phase voltage is the voltage between the phase line and the neutral line. For the delta connection, the line voltage is equal to the phase voltage, and the line current is equal to 3 times the root of the phase current; for the star connection, the line current is equal to the phase current, and the line voltage is equal to 3 times the root of the phase voltage. For practical three-phase equipment, such as transformers, motors, etc., measuring line current line voltage is easier to implement than measuring phase current phase voltage, so the nameplate is marked with line current and line voltage.
Transformer secondary side load current: line current = phase current, line voltage between three phases, phase and voltage of any phase of the three phases.
In the symmetrical three-phase circuit, the phase voltage or the line voltage can be used for calculation, but the formula is different.
Use the line voltage calculation formula:
P=1.732×U×I
Use the phase voltage calculation formula:
P=3×U×I
The introduction of the two voltages of the transformer and the related calculation methods will be introduced here. For the two voltages of the transformer, the functions and various advantages should be exerted to a greater extent to ensure the stability of the transformer voltage and achieve transformer safety. And stable operation!
