When you do a load test on a 3-phase induction motor you are checking the power factor, viz slip, and efficiency of the motor. You can test various loads with this test.
You can do that in one of three ways: 1- current on each phase, 2- phase to gnd voltage, 3- phase to phase voltage, preferably with multiple meters, the three lines has to be balanced within ~ 3%
How do you zero phase current transformer test
Using a multimeter, check the continuity of motor winding from phase to phase ( U to V, V to W , W to U ). Each phase to phase must have a continuity if winding is OK. If any particular phase fails the continuity test, your motor is probably burnt.

a test to be conduct for find the phase...
Wearing his baseball cap back to front, was just a phase he was going through.
Wearing his baseball cap back to front was just a phase he was going through.
To answer this question the voltage and the amperage of the cap must be stated. Then the termination letters can be given.
As of July 2014, the market cap for Aehr Test Systems (AEHR) is $31,342,222.96.

because y phase is y phase ...it is not b phase or R phase so it is high
