The current connection with triangle three-phase motor clamp meter measured the phase current and line current
The line current is measured. The phase current is not measured. It is in the motor.
General with the alternating current wires are respectively connected to two different phase line, clamp meter from the root voltage of 380V wire on the measured phase current, wire line end is the other side is the wire clamp ammeters from the voltage of 220V wires measured for the line current.
Current clamp meter measuring three-phase motor delta connection is phase current, current, it from one phase to another phase from the back, not as light from the phase from the zero line back, so you are measured by the phase current.
