explain why reduced voltage starters are required for large
tree phase inudction motor
Answer Posted / kj
The main reason for using reduced voltage starters is to
limit the starting current drawn by the motor. This current
can be in excess of 7 times the full load current.
If the current is not limited during starting excessively
large cables must be used and larger transformers etc. to
provide the extra current.
