After Replacement MS 2406 with new motor JonoJakarta

History: MS 2406 is 225 kW, I FL : 423 amp, 400 V, 4 poles, 50 Hz Result of new motor Insulation Resistance between phase to ground, > 40 GΩ Winding resistance each phase is 7.06 mΩ Replacement MS2406 with new motor on 31 January 2017 Replace Power cable between MCCB to Busbar Line (before size 3x1x120 mm2 to 3x2x120mm2) on 1st February 2017 Replace Contactor with new one on 8 February 2017 Measure resistance of power cable (6 cores) from motor terminal to Contactor terminal output, result : all are good (0.278Ω)

Tightening all bolt and nut at terminal. Solo run new motor without pulley on 31 January 2017. Result : R phase = 201.8 Ampere S phase = 202.4 Ampere T phase = 199.3 Ampere On 7 February 2017, took current of motor. Result: R phase = 365.4 Ampere S phase = 360.1 Ampere T phase = 386.8 Ampere

On 8 February 2017, took current and voltage. Result: R phase = 382 Ampere S phase = 380 ampere T phase = 403 Ampere R-S = 389 Volt S-T = 390.1 Volt R-T = 392 Volt On 13 February 2017, took current and result: R phase = 406 Ampere S phase = 398 Ampere T phase = 428 Ampere On 24 February 2017, took current 2 times, R phase = 416 ampere S phase = 392 ampere On 13:30 T phase = 400 ampere R phase = 403 ampere S phase = 379 ampere On13:40, adjust the underflow T phase = 386 ampere valve

On 26 February 2017, took current and result: R phase = 419 Ampere S phase = 394 ampere T phase = 405 ampere

Summary: After replace with new motor, new power cable and new contactor, and 6 times measurement of motor current, the current of motor always change, it is not high only one phase (before T phase) but the other phase also (R or S phase) On 24 February 2017, 2 times measurement. 1st condition is took on 13:30 and 2nd condition with a little adjustment of Underflow valve on 13:40. The current motor decrease while the valve little bit open.

Why do peak of current always moving between phase Why do peak of current always moving between phase? (sometimes R phase highest, sometimes T phase) Is it possible induction motor have high discrepancy (>20 amp) between phases?
