LaoThe question is unclear. If the answer does not address the correct issue, please restate the question with more details.
Three phase voltage can be measured in star, each leg to neutral, or in delta, each leg to a different leg. Assuming that neutral is balanced in the center of the phase triangle, the star voltage is the delta voltage divided by 1.732. 1.732 is the square root of 3, and comes from the phasor analysis of three phase power.
For instance, a typical three phase distribution line at 13.2 KV delta, is 7.62 KV star.
Another example is that if you know the winding current in delta, the phase current is 1.732 times the winding current.

How do you check a dc ammeter?
a dc ammeter is a ammeter which has three pins and it works by two wires.
What is the conclusion of the experiment 3-ammeter method of measuring single phase power and power factor?
This is too complicated to describe on this forum, but there are lots of web pages that describe the 'three-ammeter' method of measuring power, so your best plan is to visit one of those sites.
What is the three ammeter method?
I am assuming that you really want to use ammeters to measure power in a balanced 3 phase system. (hope you are not meaning 3 watt meter method) Power in Watt in a three phase system is equal to 1.73 x line voltage x line current x power factor. You need to know line voltage, power factor also in addition to current to compute the power. If the system is balanced then actually you do not need to connect ammeters in all three lines. One ammeter reading will do.
How can you connect current transformer to ammeter in three phase?
You use three CTs, one per line conductor, each feeding a separate ammeter,
What is the importance of ammeter?
An ammeter measures current, an important variable in electronics.
