To test 415V across phases using a test meter, first ensure the meter is rated for the voltage you are measuring. Set the meter to the appropriate AC voltage range and connect the probes to two of the three phase conductors. Ensure proper safety precautions are followed, such as wearing personal protective equipment (PPE) and verifying that the area is safe for testing. Read the voltage displayed on the meter to assess the voltage between the selected phases.
How do you zero phase current transformer test
415V commonly available wire is 300V or 600V so that would need to be 600V wire to use a megger or a hipot tester (2* operating voltage +1000V) 2000 volt megger or hipot should verify the wiring in this instance 2500v megger will be necessary for 600V wire and wiring devices you also must look and ambient temperature and humidity a test after some operation time can verify this
Voltage is checked with a volt meter. It doesn't have to be 3 phase. It is used to test any potentials across phase to phase, line to neutral, line to ground or across resistances. Be careful when testing live voltages as a misplace of the meter probes could cause an arc flash that could give you three degree burns to any exposed skin.
a test to be conduct for find the phase...
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.
because y phase is y phase ...it is not b phase or R phase so it is high

Procedure for sumpners test is the single phase transformer. This is a back to back 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.
