Lecon commissioned Neutral side FCMA+ soft starters for compressors efficiently and time bounded at AGI Glaspac. There were 5 compressors rated at 650KW,11KV. These compressors are for the new plant in AGI Glaspac as part of expansion of AGI Glaspac.
Starting current of the motor should be limited to 3-3.5 times full load current and power factor should be improved from 0.875 to 0.97 for better efficiency of the motors.
Lecon came out with a very practical solution for AGI Glaspac’s specific requirements as customer need very reliable operation from soft starter side. Lecon came out with a eccentric design which reduced the starting current to less than 3.5 times of full load current during staring and the power factor was improved to 0.95 with the help of capacitors. For increased safety of capacitor bank vacuum contactor was given instead of LBS. The market leader in motor protection ABB’s REM601 was also included in the soft starter panel for motor protection. An extra digital ammeter was given to know the reactive current supplied by the capacitors specifically. The soft starter had all the standard protections such as CPR trip, control supply failure trip, long start trip FCMA high temperature trip programmed through PLC and the program was slightly customized for customer specific requirement.
Lecon successfully designed, manufactured, and commissioned FCMA+ soft starter panel with starting current of 3.175 times of Full load current and power factor was improved to 0.95.The voltage drop was reduced to 2.76%. All the parameters came under the value committed to the customer resulting in a satisfied customer.
