Could I power a "Y" stabiliser in presence of a three-phase line without neutral ?[read the answer]
Unfortunately you cannot. The neutral is essential for the correct operation of the stabiliser.
If neutral is not available, it is necessary to connect upstream the stabiliser a duly rated delta/star isolating transformer.
The isolating transformer has to be sized in consideration of the power of the stabiliser at minimum operating voltage.
The plant / equipment has some problems caused by the power supply. What do you recommend?[read the answer]
First of all it is necessary to identify the mains disturbances.
Did you carry out any mains survey ?
If so, send files with relevant data. Our technicians will examine these data and then we will send you our considerations / proposals.
If not, our catalogue will help detecting possible mains disturbances and then adopting the most suitable solution.

I need a three-phase stabiliser. Which is the most suitable type :
"T" model with voltage regulation on the average of the three phases or
"Y" model with independent regulation on the three phases ?
It depends on the load to be powered.
"T" stabilisers are suitable for three-phase loads, well balanced input lines and a maximum load unbalance among phases of 50%.
"Y" stabilisers are suitable to have in output three single-phase lines perfectly balanced even in presence of unbalanced input lines. These stabilisers withstand load unbalances up to 100%.
Practically, they are made up of three single-phase, star-connected units. The presence of neutral is essential.
Could I power a "T" stabiliser in presence of a three-phase input line with neutral ?[read the answer]
Yes, of course, neutral is not essential for the correct operation of "T" stabilisers.
The input neutral has been short-circuited to the output neutral.
Or the neutral is of the "feedthrough" type.
