True or False: A high voltage ammeter identifies phases in a three-phase system as L1, L2, and L3.

In a three-phase electrical system, a high voltage ammeter is typically used to measure the current flowing through one or more of the phases, but it does not inherently identify the phases as L1, L2, and L3. The identification of phases is usually done through labeling or in the design of the system rather than by the function of the ammeter itself.

Ammeter readings provide information on current levels but do not provide phase identification. Phases are distinguished by their voltage and frequency characteristics in relation to each other, and special phase identification tools or wiring conventions are used in actual systems. Therefore, the statement that a high voltage ammeter identifies the phases is not accurate, which justifies that the answer is false.
