Z/ TEST
Z/ test provides capability of testing broader range of 3 Phase AC equipment for various applications
including transformer and generators. As shown below, Z/ menu is located right below “IND” menu on
the main menu
Z/ provides same functionality as IND in that the tests of contamination, insulation, resistance and
proprietary TVS are all performed, however, there are also significant differences. The IND adopts
proprietary dynamic tests which is not available in Z/ menu. On the other hand, Z/ menu can be
implemented on most of the 3 Phase AC equipment without the limit of less than 1kV rated voltage. It
also makes tests and analysis on multiple measurements including impedance, inductance, phase angle
and I/F.
Since both “IND” and “Z/” tests provide TVS, both types of test can be saved as reference record –
refer to Section “Reference Test Value Static (REF TVS)”. Therefore, either test result can be compared
to RVS.
Motor, Transformer, Motor Rotor COMP Test
When open the Z/ menu, there are three that can be selected: Motor, Transformer, or Motor Rotor
COMP. *Transformer test only available in ALL-TEST PRO 7 PROFFESIONAL.
The operation steps are the same for Motor and Transformer and the displayed results are also similar,
however, the transformer adopts a different alarm analysis algorithm from motor based on
characteristics of transformer windings.
In addition, the SAVE menu operation is also same as IND test result.
Please refer to the Section “Test Steps” under Chapter “ind/dyn/ins – ac INDuction motor test”.
Please refer to the next Section “Rotor Compensated Test” for “Motor Rotor COMP” procedure.
