There are many applications which require phase angle adjustment between voltage and current, voltage and voltage, and current and current. One example is electricity meter testing, in which the voltage and current are tested in phase and also out of phase. Another example is 3-phase (3-pole) circuit breaker testing, in which the phase angle among the poles should be 120 degrees apart.
