Measures phase voltages

With the assistance of the insertion box, it can be used to determine the total three phase power

Facilitates the insertion of different measurement devices (such

as  the ammeter, voltmeter and wattmeter) into and between the lines.

Contains three banks that will be connected to form a three phase, wye connected, resistive load

Used to vary and step down all three phases of the 230V

three phase supply by the same amount at the same time.

Steps up the output of the auto transformer in order to supply the three

phase wye connected load

Measures line currents

Determines whether a neutral current flows and its value to determine whether the load is balanced or unbalanced
