Test cos
and resonance test
These two options must be used at the same time. The purpose is to execute the manual connection and
disconnection of capacitors while displaying the cos
or THDV and THDI of each phase. This allows you to
check that the compensation unit is working correctly and whether the connection of a certain number of
capacitors is causing resonances in the installation or not. Each test is carried out as follows:
The Test cos
φ option of Computer Plus shows the cos φ of all phases and the type (inductive or
capacitive), as well as the cos
φ III (total) and its type (Fig.115).
