27. What is a useful instrument for checking 3-phase AC motor performance by measuring possible unbalanced currents?
A clamp-on ammeter is the appropriate instrument for measuring unbalanced currents in a 3-phase AC motor because it allows for non-interrupting current measurement of each phase conductor. This method identifies imbalances that may indicate motor or supply issues.
