trafo, millest üks mähis on ette nähtud seriaalselt ühendamiseks vooluahelaga, et muuta ja mõõta selle pinget, ja teine mähis on energiat mõõtev ja andev mähis
transformer of which one winding is intended to be connected in series with a circuit in order to alter its voltage and the other winding is an energizing winding
one which is often used towards the end of a power line to raise the voltage to the desired value
The booster transformer is used for controlling the voltage of a feeder at a point far away from the main transformer, and is used in railways for eliminating the flow of stray current.
