how do u connect the load to obtain 230v from a star connected 3 phase transformer?

Answer 1

230v is measured between phase and neutral therefore L1 (R) N, L2 (Y) N and L3 (B) N.

Note a star connection is Y. In your house you use 230v-240v single phase, i.e phase and neutral. Phase to phase 240√3 = 415v.

Answer 2

if in star connected, the line voltage is always going to be 230V between the phase and neutral, ie/ L1 and N, L2 and N, L3 and N

Answer 3

assuming that the secondary of the transformer is star connected (or wye) and that the phases are 230v to earth or neutral or the centre point. to get 400 across the 3 phase load connect each of the 3 'loads' or coils from phase to phase ie L1-L2,L2-L3,L3-L1. to get 230v across the loads or coils connect from phase to neutral. L1-0V, L2-0V, L3-0V

Answer 4

Between any 2 phase u should have 240 V and between any phase and neutral should give u 120 V. It is called a "y" connection.

Answer 5

you could connect effectively up too ninety% of the rated kVA of any transformer. once you've any monitoring gadget then visual reveal unit ninety% of the rated contemporary of the 'call Plate of the transformer'. Transformers are commonly made to face up to overload, many a circumstances transformers are used for even 100% lots also. Please examine for ideal upkeep of the transformer,in termss of temperature of the transformer, oil element, moisture elimination from oil and so on.

Answer 6

is it wired in a delta or a wye?
