Measurements on 10 HP AC 3 phase Electric Motor

Measurements on 10 HP AC 3 phase Electric Motor

Measurements on 10 HP AC 3 phase Electric Motor

(OP)
I made measurements on a 10 hp AC Motor 3 phase 220 volts. The motor can be connected either 220 v or 400 v. This motor is 220 v. I used Amprobe DMII PRO. I connected current probes to the load on the following sequence: Black, Red, Blue. Then I connected voltage probe to the load on the following sequence: Black, Yellow, Blue Here are the results I obtained first time:
 242 V phase to Phase Voltage
 10 Amps
 2.08 kW
 2.31 kVA
 1.18 kVAR
 PF = 0.9

Then I switched between the two voltage probes (Yellow, Blue) so the sequence becomes Black, yellow, Blue and the current probes sequence was the same. Here are the results I got:

 242 V phase to Phase Voltage
 10 Amps
 4.04 kW
 5.01 kVA
 2.86 kVAR
 PF = 0.83

Question 1: Are these readings reasonable?
Question 2: Which one is correct?

Thanks

A1. No.   A2. RTFM on the tester cover-to-cover.  Figure out proper testing on a 1ø 2W load until you get that down.  Then carefully advance to 3ø 3W measurements.  
 

RE: Measurements on 10 HP AC 3 phase Electric Motor

Suggestion:
1. Both readings are somewhat inaccurate.
2. 242 V phase to Phase Voltage
 10 Amps
 4.04 kW
 5.01 kVA
 2.86 kVAR
 PF = 0.83
appear to be more consistent/correct.
