Hello Mr.Sanjay
To identify and solve this problem we need to know the following informations
1) Capacity of the compressor motor & its rating
2) Type of starter and overload setting
The reason for high starting current could be due to
defective contactor resulting in phase failure,voltage drop or
faulty bearings causing motor jam or
fault driven compreesor or
due to backpressure
First try to run the compressor in unload condition.If the problem remains the same check if the correct voltages reaches the coil.If it is o.k.,then it is better to separate the motor coupling to locate wether the problem is in the motor or in the subsequent stages.
Hope this could be of little use in solving your problem.
with regards
